Initial Review, 250 Miles on Tires
April 20, 2013

I just got back today from using these for auto-x on my 93 Corvette with Z07 suspension and aggressive alignment. These tires just plain work, even on a heavy car in cold/wet/dry conditions. It was actually snowing and later got up around 45 or a little less. I kept pace (within a couple tenths or so) with near FTD C5Z06 (Hoosiers, not good at all in those conditions). I was impressed, dry grip is excellent. Breaks away predictably and smoothly. Tires do perform in cold/wet/dry conditions, with due caution exercised.

Quick warm up on tires, only 3 runs and they were warm. Grip got better as I went.

Excellent tire and works well on my Corvette.

Bought a complete set of these for my 98" C5 Corvette, manual 6spd. & Z51 Suspension.
What a diffence these tires made in the ease of steering at slow speeds when navigating parking lots. Put a little over a thousand miles on these during our trip up to Lake Tahoe. These tires are by far quieter than any other tire I've had on this car since I bought it new. The OEM Goodyear Eagle EMT's that came with the car were by far the worst. I had them replace in the first six months after spinning out on the freeway. I switched over to the non EMT Eagles and they were better but didn't last-13K miles. For my 3rd set of tires I switched over to a complete set of Bridgestone S03 Pole Positions which were an excellant set of tires, but no longer available. I managed to get 23K out of them and they still had tread left on them. Replaced them due to age, 9yrs and hard. These new Michelin Pilot Sport A/S Plus tires are an excellant fit for the Corvette. I had them mounted and balanced at Corvette Mike's in Tustin,California. The tech their was telling me that I could have bought the EMT version of this tire as well, and that their is very little diffence in the ride and handling performance between the two. He also said that I could expect to get twice the milage out of them over the S03' that I had taken off.

New 18" Lightweight Rear Wheels for the C6 Z06

Friday, August 5, 2011 by Cy Chowattukunnel
With summer timOZ Allegerita Anthracitee here, it's time to get your Corvette out and go! Of all the cool sport cars that we get to work with, the Corvette is among my favorites because so many Corvette drivers drive their cars daily. What's the point of having a great car if you're not going to drive it? 

For C6 Z06 drivers that drive on the street and the track, rear 18" lightweight wheel availability has been limited until now. O.Z. Racing has introduced an 18x12 57mm offset Alleggerita HLT that's ideal for track use.

The anthracite painted (pictured above) and black painted finishes are currently available, while other painted finishes can be special ordered for delivery in approximately 60 days include blue, gold, orange, red and white.

Since the C6 Z06 typically comes with 18" front and 19" rear Original Equipment sizes, it's not possible to display the 18" wheels on our Upgrade Garage, so contact a sales specialist for assistance.

Combined with the 18x10 40mm offset front size ($399* Anthracite, $414* Black and $429* other finishes) you can run the following custom fit track fitments of 345/35-18 Hoosier R6 or A6 in the rear and either 295/30-18 or 315/30-18 in the front.  These custom fit track fitments are aggressive fitments where the edge of the tire will be further out towards the fender. Suspension modification may be required to clear the fender lips.

This 18" combination weighs 3.8 lbs. less per rear wheel compared to the 345/30-19 Hoosier R6 on 19x12" O.Z. Racing Ultraleggera HLTs. 3.8 lbs. Less rotational weight will significantly improve braking and accelerating at the track. Read "Road Wheel Weights Can Affect Your Vehicle's Show...and Go" to see how lighter wheels can affect a vehicle's ability to accelerate, brake and corner.

Keep in mind that the above tire sizes are custom fit options, so whether or not you rub depends on a number of factors:

1) Suspension modifications and/or suspension wear
2) Alignment, specifically camber setting
2) Road conditions
3) Tire tread width
4) Amount of load the vehicle is carrying  
 
A custom fit is a size or part that you can test fit but not drive on. I would also recommend getting anecdotal feedback from other drivers with the same vehicle before making your purchase.

Autocrossing with Bridgestone, Dunlop and Hoosier!

Saturday, May 14, 2011 by Hunter Leffel
Here in the Midwest, the temps are rising, the sun is out and drivers are bringing out the toys. Lets go racing! Tires are what makes it all happen. All the power and suspension in the world is for naught if the tires don't deliver the goods. Tire Rack has test results and reviews on Extreme Performance and R-compound tires.

Bridgestone RE-11
Bridgestone Potenza RE-11
Dunlop Direzza Sport Z1 Star Spec

Hoosier R6
Hoosier R6

Extreme Performance tires deliver the most dry traction you can obtain without going to an all out dedicated track set up. These are completely useable in street applications while providing ample grip for weekend track events and serious auto crossing. While encompassing both street and track use, our latest test results favored the Bridgestone Potenza RE-11 as the best all-around tire. It was the easiest tire to drive at the limit while also providing the most comfortable ride on the street. Read the full test report.

When you are ready to take the next step, you will want to look at Track aka R-compound options. Even though the tires are street legal, they are not recommended for street use. This is due to soft compounds and other track specialty features that make them less than ideal for daily driving.

Take a look at what consumers had to say about their experience with each tire:

"[The Bridgestone Potenza RE-11] is a perfect street tire for occasional track use." -- Tire Rack Consumer Review, 2008 BMW M3 Coupe 

"[The Dunlop Direzza Sport Z1 Star Spec] is an amazing tire, overall grip is very close to an R-compound tire." -- Tire Rack Consumer Review, 2003 Porsche Boxster S

"...Hoosier track tires are my favorite. I can depend on them for maximum grip."

Coil-Over Kit Basics

Tuesday, August 17, 2010 by Logan Woodworth
Bilstein PSS10 Coil-Over KitCoil-Over: an automotive suspension device which refers to a spring or "coil" mounted over the damper (shock or strut).

There are advantages to the coil-over versus a conventional spring and damper system that include ease of installation and simplified height and stiffness adjustment. Many coil-overs offer easy fine-tuning that's not available from conventional suspension systems.

Coil-Over Kits are available for many German vehicles such as Porsche, BMW, Audi, and Mercedes-Benz. There are also many domestic and Japanese fitments for cars such as Corvette, Mazda Miata and RX7, Nissan GT-R, 350/370Z, and many others.

Suspension Upgrade 101

Thursday, June 3, 2010 by Brandon Lorenc
When upgrading your car's suspension, it is important to remember that you're going to be the person doing the driving and will have to deal with the ride quality on a daily basis. Whether it is MINI Cooper Suspension, Corvette Suspension, Mustang Suspension or WRX Suspension there is usually a trade-off in ride quality for performance.

Personally when I upgraded the suspension on my 2005 Saab 9-2X Aero (essentially a WRX) I wanted a good balance of ride quality and improved handling. I used the H&R Sport Springs which gave an excellent improvement in cornering and steering response and a more aggressive look, but still retained a decent ride quality. It lowered the car slightly more then an inch in my case which was just perfect for me. Many people go more aggressive, but remember you're driving down the road casually much more often then when your cornering and will have to deal with the ride quality on a permamenent basis.

Have fun!

Mac at the Rack!

Thursday, February 25, 2010 by Mac McNabb
I love to drive! Fast, off-road, track.....back roads, you name it. Soon after getting my license I realized that gasoline flowed through my veins and driving would always be a priority in my life. 

I have owned Camaros, Mustangs, 04 Mazda RX-8, 1969 Ford Galaxie Convertible, Hondas of all varieties, lifted 1985 Toyota off road truck; you name it. All of which I enjoyed driving for one reason or another.

Now that I have a family, it has been harder for me to have the sports cars but the Honda Odyssey is great....kinda..... and the Galaxy still is cool.

We have used car shows for family time in the summer and really miss all the opportunities to see car shows from the earlier family days in the suburbs of Chicago. My boys could recognize at 2-3 yrs old every generation of Corvette, Mustang and Camaro from the tail lights alone in the dark....that makes Dad feel pretty special.

Here at Tire Rack I get to share my love for driving and cars/trucks with each person I speak with. I know that positive attitude and excitement help communicate just how important tires are to your driving experience. Feel free to call me with your brake, suspension, wheel and tire needs for sure! I am here to help!

Michelin pulls off a historic upset

Thursday, July 23, 2009 by Luke Pavlick
Can you really use the term historic when talking about a tire?
Some say "yes" some say "no". 

    If you look at the way in which a tire achieves such status you can make a valid argument for either answer. I think the issue is not, if a tire is 'historic' but, the circumstances which lead a given tire to be placed in a historic position.

   Goodyear is the 'SPEC' tire company for NASCAR, which is the most popular race series in the world right now. Does that make the Goodyear Racing Eagle historic or is it just good product placement?

You may have heard comments on the tires that were at the 2008 Brickyard 400 from the likes of Tony Stewart and other NASCAR drivers. Tires which basically turned the whole race into a pitstop competition which was eventually won by Jimmie Johnson.

    Not the kind of history I would want to be associated with but,it is said that "any press is good press". Anybody want to ask a Goodyear exec if that still holds true?










Much like Goodyear & NASCAR, Firestone is the spec tire for the Indy Racing League races.









while over at Formula 1 Bridgestone is the tire of choice









and Dunlop has won at 24 Hours of LeMans more than 30 times.

    This years classic 24 hour endurance race saw 41 of the 55 entries on Michelin tires. The Michelin shod entries completed 11944 laps which adds up to an astounding 101,153 miles.

   




All great marketing moves, which lead to equally great achievements but, in my opinion  not really 'historic'.

Here's something I believe could be considered 'historic' to a car guy like me.
   
    The Chevrolet Corvette has been THE American Sportscar since 1953. The automotive press has repeatedly called it an iconic car for the ages. Yes, times have changed, GM management has cycled through and designers have come and gone but, the Corvette has survived and some say even thrived regardless of the happenings around the world. Over the years 6 different generations have left the assembly plant.

    The one thing every Corvette has shared is the Goodyear tires which were installed at the factory. That's right for 56 years every Corvette built came with Goodyear performance tires. 

    In 2009 Chevrolet introduced the King of all Corvettes. the ZR1 which sports 600+ horsepower and can legitimately compete with any supercar in the world.
 
 
 
    True to it's heritage, The ZR1 delivers world class handling and performance but, there's something different about the newly crowned King. Unlike the 56 years of Corvettes that came before it, it doesn't have Goodyear Performance tires. 

    The engineers at, the french tire company, Michelin developed a tire which was so finely tuned and mated to the ZR1's suspension, chassis and dynamics they were able to gain the OE application with their new Pilot Sport PS2 ZP. The relationship between Goodyear and the Corvette was not strong enough to stop the advancement of a better performing product. 


The Pilot Sport PS2 ZP is the first non-Goodyear Corvette OE fitment ever!

    The tire is designed to combine world class traction, handling and cornering with an advanced tread rubber compound which is molded into an asymmetric tread design featuring Michelin’s Variable Contact Patch to keep more tread rubber on the road during a variety of maneuvers. The tread design features large outboard shoulder blocks and continuous intermediate and center ribs to provide a solid connection to the ground for control during cornering, braking and acceleration in dry conditions. According, to what I have read and what I have witnessed, it is the first runflat tire I have ever seen which can and does out-perform it's non-runflat counterpart.

    What can you do after a coup like that? The engineers from Michelin went back to the drawing board and re-engineered the Pilot Sport PS2 ZP and came up with specific versions for the C5 and C6 Chassis Corvettes. Since then, the tire has proven itself to be the top choice for Corvette owners who want the most out of their driving experience.
