My suspension is tuned for corner carving performance and these tires are TERRIBLE! It felt as I was driving an old land boat! My stock truck felt safer than my car. These tires felt dangerous to drive on in corners and any speed on the highway. Enroute to work I take a curve at 85mph safely with good tires and I could barely drive 60mph with these on the same curve.

The size is 275/40 17 on my car. Different size tires might have a better performance.

Road noise is virtually not there. Didn't drive in snow or rain.

These do have a 30 day return policy which I took advantage of.

Good luck in choosing the correct tire.

I replaced a NEW set of Continental DWS tires as I had the feeling that they were just a bit to soft for the suspension set-up on the Mazda3 GT which for anybody out there that dosent know Mazda -this suspension is very very firm .in 2010 it was revised to be more ameniable to regular driving yet still has its roots in a performance setup .
Given that the DWS are great tires but fro the right car/ and proabably Truck/ Minivan even better . They were all-around dry-wet-snow hence DWS so I saw that Bridgestone had a new tire the S-04 and the metamorphisis was immediatly noticeable and I cringed while waiting to hit my first road imperfection or pothole because the car is unforgiving with performance tires , alas --I hit road damage and it ate it up without a jarring hit as if I had rolled over a small grenade . My pervious experience with some Yokos that were very hard gave me to blowouts from pothole hits while relatively new ......but these S-04s have been prerforming far beyond my expectations ---gripping like a cat in panic mode and forgiving enough to let you drive in urban enviroments without constant fear of that imminent pothole from -------- that leaves you wondering how much damage that did to the bushings , alignment or tires? These hold like glue and make me pine to get out and just drive even to work ---It makes the car handle like I believe it was engineered to by the Mazda techs . Many may laugh that have thier "bmws" or audis or other cars that people just assume are the best handling cars out there , but those that know Mazda know what I talking about .
I had a chase thru a nasty set of chacanes near the ocean with a Lambo G and the guy could not shake me as he clearly forced me to yield and let him pass as I did --but he never got away from me til we hit the straights where the extra 450hp made the diffirence ,,,but in the twistys he was sweating bullets in amazment or shock ? great tires.

Tire very quiet for off-road tire. Excellent handling tire (Beefed-up suspension on Tundra). Highway and around town handling is great. They got me through the snow/ice in Sequoia, sandy beaches in Mexico and off roads in Arizona, Baja California, Utah and Southern California; I broke tires in for first 500 miles as recommended. Rotated and checked pressure regularly, I think this has paid off (very important). I've put them through some fairly aggressive driving and tires have handled extremely well. Truck drives and handles like a dream with these tires! If you have the money, buy these tires. Highly recommend. Tundra has153K and tires 107K!!! I am replacing with the same tires.

These were great overall. My truck only has 15 inch wheels so the profile is a bit tall, despite this the steering on curvy highways felt very sharp and controlled. Off road, they never let me down, even in deep mud or on steep hills. In snow they did well, and I never felt hydroplaning until the tread got pretty low. My only complaint about ride comfort is that in very cold weather I felt a bit of vibration, though this could also be the bushings in the suspension. Aside from that they are pretty smooth as far as off road tires go. I've put about 50,000 miles on them so far and still have some to go, probably going with these again.

Replacement Trailer Tires

Friday, May 4, 2012 by Hunter Leffel

Recently, we added the Power King Towmax STR to our trailer tire line-up that also includes the Goodyear Marathon Radial. By adding the Towmax STR tire, we now have more sizes and load ratings available for customers looking for Trailer Service tires.

Both tires are similar in their exterior features. A rounded shoulder with an internal polyester cord body provides a smooth and stable ride. Circumferential grooves provide ample water evacuation. Constant and consistent contact with the road is achieved through the solid center rib and symmetric tread design.

Goodyear Marathon Radial

Both the Goodyear Marathon Radial and Power King Towmax STR are radial construction. We don't offer bias ply lines. Additionally, Tire Rack only offers modern tire sizing in the form "ST205/75R15."  If you have an older tire with a classic size such as 6.50-15, you'll need to convert to a modern size first. To make the conversion simple, take a look at this table.

Special purpose trailer tires aren't intended to be used on cars or light trucks and are not UTQG rated. Your trailer will be more stable and pull better on tires designed specifically for trailer use. Since Special Trailer tires are constructed with heavier duty materials, they are tougher than typical passenger vehicle tires. This is a plus because trailer suspension systems are generally stiffer and less sophisticated than automotive suspension systems. For more information on a trailer tire's design, read "Trailer Tires vs. Passenger Vehicle Tires."

Unfortunately, the truck these tires were put on was totaled in an accident less than 9 months after getting the tires. But, they performed well in the short time they were in service, excellent snow and wet traction! Low noise for an all terrain tire - major surprise. Bottom line: even though my Ranger was 2wd, it had 4wd suspension and ride height and performed better with these tires than with even the OEM Firestone tires!

How to Choose a Suspension Upgrade

Wednesday, November 30, 2011 by Logan Woodworth

Coil-Over Kits The most popular upgrade for cars and trucks is new custom wheels and tires. After that, suspension upgrades are very common on both late model and older vehicles. Typically, drivers will want to simply raise or lower their car or truck for aesthetic reasons, but there are often performance reasons for suspension upgrades, as well.

Raising, often referred to as lifting, is most common on trucks and jeeps. In addition to creating a taller ride height, this is regularly done for performance reasons such as allowing for larger wheels and tires than what the factory (O.E.) suspension will allow.

There are two primary ways for lowering a vehicle: lowering springs or an adjustable coil-over suspension kit. Both of these options will give the car a lower center of gravity and stiffen the car's chassis, which will allow for less body roll in corners and improved handling and cornering. Coil-overs give the added advantage of ride-height adjustability and with certain models, dampening adjustability for fine tuning the balance of ride quality and handling.
Coil-Over Kits
Whether you're looking for performance shocks, gas shocks or other products to upgrade your suspension, it's important to consult with an expert. Changing a car's suspension will require alignment adjustments and may create fitment challenges with your custom rims (wheels) and tires.

Which Shocks Are Right for My Car?

Monday, October 17, 2011 by Alex Mouroulis
KYB Gas-A-JustHave you ever felt that your car bounces more after you go over a bump? It just doesn't feel as connected to the road as it did when it was new? Shock absorbers are an expendable item that has a big effect on your ride quality. When it comes time to replace shocks, you're going to have access to your springs. This is a great time to add lowering springs.

Not every shock is designed for all driving circumstances. There are two major categories for aftermarket shocks: performance and touring.
  • Performance shocks give the firmer ride, and help reduce body roll. They are often combined with lowering springs for the ultimate handling combination.
  • Touring shocks are more focused on a soft, compliant and comfortable ride. Touring shocks add to that supple, luxurious ride by soaking up more impacts and road imperfections.
Listed below are a few terms that will help you better understand the characteristics of a shock adjustment:
  • Compression - The collapsing stroke of a shock, directly correlated to the movement of your axle.
  • Rebound - The return stroke of a shock, directly tied to vehicle pitch and ride quality. To learn more about shocks check out, "Damper Dynamics."

Take a look at a few of the shocks available at Tire Rack:
  • KYB Gas-A-Just: An Original Equipment replacement shock.These are your excellent-value option, as they are self adjusting.
  • KYB Monomax: Increased load control, and a firm planted feel for your light truck or SUV. These shocks have been known to offer a firmer ride, but the trade off is better control. These shocks are self adjusting. They completely transformed my Chevy Blazer back to the consistent like-new handling I missed.
  • Koni STR-T:  A cost-effective performance shock, designed to offer better handling, without a harsh ride.
  • Bilstein 5100 : Designed with the lifted truck or SUV in mind. These are ideal for your Jeep or pickup truck with mild body and suspension lifts. The articulation in off-road circumstances is superb.

Off-Road Maximum Traction vs. On-/Off-Road All-Terrain Tires

Tuesday, October 11, 2011 by Logan Woodworth
When searching for an aggressive looking tire for their truck, Jeep or SUV, many customers also want good ride quality and low noise from their set. Off-Road Maximum Traction tires, which are often referred to as "mud-terrain" or "mudders", have very aggressive tread designs and look great on vehicles with an aftermarket lifted suspension. However, tires in this category are certainly louder and ride rougher than On-/Off-Road All-Terrain tires. Some of the more popular choices in the Off-Road Maximum Traction category include the Goodyear Wrangler MT/R with Kevlar, BFGoodrich Mud-Terrain T/A KM2 and Kumho Road Venture MT KL71.

For many drivers, ride and noise comfort are a small price to pay as they truly are looking for the most aggressive look and best off-road traction. For others not willing to sacrifice as much ride and noise comfort, an On-/Off-Road All-Terrain tire may be the best choice.

On-/Off-Road All-Terrain tires are a practical compromise between Off-Road Maximum Traction and Highway All-Season tires. These tires are great for drivers who find themselves on unimproved roads or long gravel driveways. Even within this category, there are some options that are more aggressive than others and tend to perform closer to a Off-Road Maximum Traction tire. A few of the tires include the BFGoodrich All-Terrain T/A KO, General Grabber AT2 and the Dick Cepek Radial F-C II.

Justice for Your Truck, Jeep or SUV: Closeout Pricing on the ATX Justice

Friday, September 23, 2011 by Cy Chowattukunnel
BorATX Justice Machined With Flat Black Accentsed with the look of your truck, Jeep or SUV? Well, how about spiffing it up with the Justice wheel from ATX.

For example, most 2008 Jeep Wrangler X's come with 29.3" diameter 225/75-16 tires from the factory. The ATX Justice is a lower offset wheel which is ideal for a lifted Wrangler running an over-sized, custom fit tire size.

An ideal set up would be the 31.9" 275/55-20 Pirelli Scorpion ATR's on 20x9" -12mm offset ATX Justices at $1276* (excluding TPMS sensors) plus shipping. The ATX Justice will upgrade the look of your vehicle, while the Scorpion ATR offers a unique combination of aggressive looks with great on-road handling.

Keep in mind that the above sizes are custom fit options that you can test but may not be able to drive on because whether or not you rub depends on a number of factors:
Pirelli Scorpion ATR
1) Suspension modifications and/or suspension wear
2) Alignment, specifically camber setting

How Do I Change Tire Sizes on My Car Safely?

Monday, September 19, 2011 by Doc Horvath

Tire and Wheel MeasurementWhile the wheels and tires that are equipped on new cars have been designed to compliment the car and provide an acceptable level of comfort and handling, many of our customers feel that they are not necessarily the best "fit" for their individual taste. In most cases, changing the wheels and/or tires is a great way to personalize your vehicle quickly and safely. However, how do you know which sizes will fit your vehicle? Leave that to us!

When a new model of car or truck is released, we will bring the vehicle in to our facility for evaluation and measurements. When verifying wheel measurements for each application, we measure:

  • Bolt pattern
  • Centerbore
  • Hub interference
  • Load capacity
  • Lug hardware
  • Suspension components
For more information on how we measure critical components of your vehicle, read "How We Know What Fits." Performing these tests guarantees that the tires and wheels we sell you are going to fit your vehicle. These measurements also ensure that there will be no issues with the accuracy of your speedometer/odometer which could also affect the ABS or traction control system the vehicle may have. A tire that is too small (or too tall) can confuse the electronics of the car and cause these systems to malfunction when needed.

Shop by vehicle to find the tires and wheels that are sure to fit your vehicle!

On the Level

Friday, June 24, 2011 by Jonas Paeplow
Pickup trucks are some of the most popular vehicles on the road today, but many people don't use their trucks for what they were originally intended... hauling a load.


On many pickups, especially 3/4 and 1 ton applications, using the vehicle as a daily driver with little or no load in the rear creates a rear end high, front end low configuration or "positive frame angle".

Positive Frame AngleSpecific vehicles like 1999-2006 Chevrolet/GMC trucks have alignment specifications that require frame angle to be added or subtracted to the caster reading. Basically this means the specifications for these vehicles are written to a zero frame angle.


Illustration courtesy of SPC Performance

Caster is the angle to which the steering pivot axis is tilted forward or rearward from vertical, as viewed from the side. If the pivot axis is tilted backward (that is, the top pivot is positioned farther rearward than the bottom pivot), then the caster is positive; if it's tilted forward, then the caster is negative.


Caster angleCaster is affected mostly when a vehicle has a large front to back difference in ride height. This may also be because of heavy loading in the rear of the vehicle or "negative frame angle". The frame angle will directly affect the caster in a one to one relationship. That means for each degree of frame angle change the caster will change one degree. Positive frame angle will be added to the caster reading whereas negative frame angle would be subtracted from the caster reading.

Illustration courtesy of Grassroots Motorsports Magazine

Caster does not affect tire wear but it can affect how well the vehicle steers. Excessive positive caster will cause an increase in steering effort, especially for low speed maneuvers, such as parking. Negative caster can cause the truck to have poor directional stability, make it tend wander and not return to center. The addition of larger than stock tires or 4WD only compounds these conditions.

If you don't carry heavy loads, a leveling kit can help with steering issues, even if you don't want to put larger tires on your truck. If you do want larger tires, installation of lift and level kits will allow for the use of up to 35" tall tires with 17"-26" wheels and near stock offset, without rubbing, depending on the application.

When shopping for a lift kit for your pickup truck, it is important to keep in mind that there are just a few ways that a lift can be performed. Some systems relocate the suspension brackets and require the removal of all suspension components to do so. Others increase spring pressure and result in a stiffer ride. Tire Rack carries lift and leveling systems by Traxda and Bilstein. Each have their own method of lifting or leveling your vehicle.


Traxda's method relocates the mounting point of the spring that holds the truck up without changing the location of the stock suspension arms. Install is simpler and easier and doesn't compromise the stock ride. Each application is designed to ensure stock compatibility and quality. For example, with a coil-over shock style suspension the strut length is extended while retaining the stock spring pressure. This keeps the smooth ride of a stock truck, with no increase in harshness. For a torsion bar style suspension a re-indexed torsion key and shock relocator brackets are included to change the location of the torsion spring mount without changing the spring tension.

Truxx Lift and Level KitTraxda Lift and Level Kits raise the front of the truck 1.5" to 3" (depending on the vehicle) to eliminate positive frame angle and provide the clearance necessary to run larger wheels and tires. For some applications, the rear of the truck can be raised 1"-2" as well leveling the truck and compensating for the heavy loads used in a working environment (negative frame angle).

Most kits are a direct bolt-in style, simple and easy to install with nothing more than common hand tools and require no modifications to your vehicle. The kits retain stock ride quality. All Traxda kits come complete with hardware, full instructions, alignment specs and dedicated technical support.

Bilstein's ride height adjustable 5100 Series replacement shocks for coil-over design front suspensionBilstein 5100 pickups utilize the vehicle's existing stock coil spring.

The 5100 Series (Ride Height Adjustable) shocks feature multiple snap-ring grooves on the body of the shock to accommodate different spring seat positions, allowing height adjustments from 0" to 2.5", depending on the application. By raising the spring seat position, the factory rake (positive frame angle) can be altered to achieve a level front to rear ride height while accommodating up to 33" diameter tires. Bilstein's self-adjusting valving delivers improved damping control and a smooth ride on all road surfaces at any speed.

You don't have to live with poor steering, tire binding, steering wander and rough ride, just keep it....
"on the level."

Looking for a Lift?

Wednesday, September 15, 2010 by Porter Pryde

Thinking about a suspension lift for your truck, but you don't want an overly stiff ride?

Consider the Traxda Lift and Level Kits.

Traxda kits lift your ride by relocating the mounting point of the spring that holds the truck up without changing the location of the stock suspension arms. Installation is simple and does not require the removal of all suspension components like many kits. Because spring pressure is not increased, it doesn't compromise the stock ride.
Each Traxda kit is fine-tuned to your vehicle to ensure stock compatibility and quality. 

With a coil-over style suspension, the strut length is extended while retaining the stock spring pressure. This keeps the smooth ride of a stock truck, with no increase in harshness. For a torsion bar style suspension, a re-indexed torsion key and shock relocator brackets are included to change the location of the torsion spring mount without changing the spring tension. 

All Traxda kits come complete with hardware, full instructions, alignment specs and dedicated technical support. Most kits are a direct bolt-in style, simple and easy to install with nothing more than common hand tools and require no modifications to your vehicle.

Ever get that uneasy feeling?

Saturday, July 24, 2010 by Doug Moore
Worn out shocks and struts can not only give your vehicle that unstable feeling, but can also contribute to abnormal tire wear, pre-mature suspension wear and can affect your car's ability to handle in an emergency situation. Typical life expectancy is about 50,000 to 60,000 miles. Your shocks may look fine, but internally the components have worn and are not operating efficiently.

Shocks and struts are made for all types of vehicles and performance needs.

In the performance category, we have products from Bilstein, KONI and KYB. Each is engineered to provide excellent control and improve the responsiveness of your vehicle.

If comfort is more of a priority, Bilstein and KYB have replacement shocks engineered to bring back that new car feel.

For the off-road entusiast, or if you just need something heavy duty for towing or load carrying on your truck, the KYB Monomax will provide that higher level of control that you require.

As always, you can shop by vehicle to see products sorted by performance category.

At Tire Rack, we offer the Superlift Level-It Kit that works with Original Equipment suspension components to achieve modest ride height gains. And by modest, we mean 1.5 to 3.5 inches of additional height.

All components of the kit are engineered to provide a precise fit, and you'll use one of three methods depending on your vehicle's existing suspension system: strut extensions, torsion keys or coil spacers. All install in a relatively short amount of time. too. Of course, you'll want to shop by vehicle to make sure this kit is right for you.

Looking to lower your vehicle?

Monday, June 21, 2010 by Tire Rack Team
Tire Rack offers a number of high-quality suspension products that can take your vehicle down a notch, but first, make note that you shouldn't go any lower than 1.5 inches below stock settings. We'd hate for you to negatively affect ride and drive performance.

That said, we're big fans of H&R Springs. They're made in Germany and precision-wound with the highest quality spring steel available. You can choose from Sport and Race springs depending on your vehicle and how you drive it (H&R Springs Comparison Chart).

We also like Hotchkis Springs. Sport Suspension, a leader in the suspension industry, engineers high quality products for domestic muscle cars, SUVs, and pickup trucks, plus European performance vehicles and Japanese sport compact vehicles. Their Sport Springs are popular among our consumers, and we think you'll like them, too.

Of course, choosing aftermarket suspension products has everything to do with your specific vehicle. You'll want to shop by vehicle, after which Tire Rack will create a detailed list of options that you can choose from.

Not sure you want to lower your vehicle? Take a look at lowering to get a better understanding of what your vehicle would look like sitting a little lower to the ground.

Need a little lift?

Wednesday, June 9, 2010 by Austin Martin

See a tire or wheel package you would like to put on your truck or SUV but you do not have enough clearance for them to fit properly? Superlift and Traxda makes suspension lift kit or sometime it's called a leveling kit that will give you a little more clearance that you are looking for. These kits are designed to lift the front suspension to level the vehicle. On most trucks or SUV the clearance problem is the front, the rear usually have plenty of clearance. The kits work with factory suspension components to achieve modest ride height gains. Installation is straight forward and normally inexpensive. If you only need 1"-3' of clearance these kit will do the job. The Superlift and Traxda lift systems utilize one of three methods to achieve increased ride height depending on the vehicle’s suspension design. With the Coil Spacers system it allowed me to be able to put 33" tires on my Toyota 4Runner and I was able to install the kit in my own garage. Note that some special tools are required and this should only be attempted by a qualified person with experience.



Strut Extension - Most late-model 1/2-ton trucks and SUVs utilize a coilover strut for the front suspension; the shock and coil spring are together in one compact unit. A simple strut extension is utilized on these applications. This involves adding an application-specific spacer to the top of the factory strut assembly. This method does not preload the factory coil spring (which would degrade ride quality) or over-extend the factory shock. No modifications to factory-installed parts are required and no time-consuming dis-assembly of the factory strut is needed. The strut extension is easily removable should the vehicle need to be returned to stock, and some applications include modified extension stops if needed. Level-It strut extensions are the most cost-effective and efficient way to level the stance of your late-model truck.




  • Mounts on top of the factory strut assembly
  • Allows the use of plus-size wheels / tires
  • Easy installation and removal – no strut dis-assembly required
  • Ideal for restoring height lost from heavy front bumper / winch combos
  • Enhances appearance by leveling the stance of the vehicle
  • 10.9 grade metric hardware included
  • Limited Lifetime Warranty


Torsion Keys - Vehicles equipped with torsion bars have a certain amount of adjustment built into the factory system. This suspension height adjustment takes place via a bolt that indexes on a torsion key attached to each torsion bar. Simply “cranking up” the factory system is not the right way to go about gaining minor amounts of lift due to a number of factors. Level-It torsion keys are direct replacements for the factory pieces but feature different torsion bar indexing. The forged-steel keys are 25% stronger than the cast factory pieces, and when necessary new metric hardware is supplied to prevent “over-cranking” the bars. Shock extension and mounting tool adapters are also included with some applications.


  • Heavy-duty forged steel construction is 25% stronger than OEM keys
  • Provided 1.5” to 2.5” of adjustable lift height
  • Designed to grab the “flat” of the torsion bar for a tighter fit
  • High-gloss powder coated finish
  • Shock extensions included with some applications
  • 10.9 grade metric hardware included
  • Limited Lifetime Warranty



Coil Spring Spacers / Block Kits - Applications that utilize a coil spring front suspension utilize a coil-spring spacer to achieve lift. In most 4WD applications, this spacer is constructed from laser-cut steel and mounts on top of the factory coil. Most 2WD vehicles utilize a steel-encased urethane spacer that will not deteriorate or decrease ride height over time. Both designs ensure silent operation as the suspension cycles. When necessary, shock extensions are also included.

With some of the taller lift heights (3" to 3-1/2"), the amount of lift exceeds the factory rake. This results in a slightly rear-low stance that is popular in some areas. However, for those that want to maintain a level stance, or the traditional rear-high stance, a variety of different block kits are available to suit every taste or preference. All block kits are sold separately.



  • Steel-encased urethane spacer construction will not deteriorate or decrease ride height over time
  • Urethane provides a smooth and quiet ride
  • Some spacer kits include shock extensions
  • Lift blocks include OEM features for proper spring pad engagement and bump stop function
  • Block kits include U-bolts and hardware
  • Limited Lifetime Warranty


High performance tires and "tramlining;" how does that affect me?

Tuesday, June 8, 2010 by Doc Horvath

The term "tramlining" is being used to describe when directional control is disrupted by the vehicle's tendency to follow the longitudinal ruts and/or grooves in the road. Its name could be compared to the tram or trolley driver who does not steer because his vehicle follows the path established by the tracks.

On the road!Any vehicle can exhibit tramlining on certain areas of the highway because of uneven pavement or severe rutting. And all vehicles tramline to some degree rather than obediently following the driver's steering input. For example, there's usually at least a small change in steering resistance felt through the wheel when crossing an uneven expansion joint or asphalt junction during lane changes.

Many high performance tires feature a directional tread pattern, and that pattern can make tramlining a stronger possibility. With a wider treaded tire, you may encounter more longitudinal ruts and/or grooves in the road than a narrow treaded tire. A tire with large tread blocks that transmits the driver's input to the road with great precision will also transmit the road's imperfections back to the vehicle's suspension. And because tires become more responsive as their tread depth wears away (which is why tires are shaved for competition and track use), a tire will become more likely to tramline as it wears.

When looking at high performance tires, take a moment to consider the roads you encounter every day. If you travel the highway quite a bit, and if the roads are well worn from heavy truck travel, then you may want to steer away from a directional tire!
