Want the Best Traction and Longer Treadlife from Competition Tires? Heat Cycling Delivers

Tuesday, March 27, 2012 by Zig Ziegler

The first run of a competition tire's life is the most important. If we look at tire construction from a microscopic level the tire is made up of many weak and strong molecular bonds. During any run a tire will stretch and flex which breaks the weaker bonds and generates heat. However, if you take your new tires that have never been driven on to the track and push them too hard and too long, you'll also break some of those stronger bonds. Breaking down these stronger bonds compromises the tire's ultimate grip.
 

In order to get the most life and best traction from your competition tires it's recommended to heat cycle them before competitive use. Tire Rack uses a heat cycling process which puts an inflated tire between rollers and applies pressure while the tire is brought up to speed. The natural deflection of the tire will build up heat within the tire's normal operating range. There's no artificial heat needed. The roller process allows the most even heat distribution across the entire tread of the tire which gives a more precise heat cycle than can be attained on the track.
 

Once the proper temperature is confirmed with a pyrometer, the tire is stamped to designate it's been "Tire Rack Heat Cycled." It's recommended that the tire not be driven on for 24-48 hours after heat cycling so the bonds broken during the process can reform in a more uniformed and stronger orientation. Hoosier racing tires, as well as competition tires from Yokohama and Kumho should be heat cycled before they're used in competition.  
 

Tire Rack's heat cycling service can be added to your order for $15 per tire. Take a look at our competition tires to see how Tire Rack can help you have a more successful racing season.

This is the OEM summer tire on the 2012 Nissan GT-R. Daily driven, these are fantastic in the dry and light rain. With half-tread left, they like to hydroplane in standing water.

I used these tires to place 7th in the 2011 Spectre 341, better than many people with modified cars and Hoosier A6/R6 race rubber. They are great, if not a little expensive.

Been R6 fan but they are very sensitive to alignment (uneven wear). Just came back from VIR event and have all good things to say about this tire (C51). Takes a couple laps to warm up when stone cold but no different than R6's. In terms of grip, unless back to back, wouldn't be able to tell difference between these and Hoosiers. Seems to be more tolerant of alignment changes. Will need to report back next season regarding how much longer they last vs. Hoosiers. I have 10 30 min sessions in instructor group on these and they seem to be in much better shape vs. my R6 experience. They also hold their pressure better than R6's on my OZ allegeritta's - R6's randomly lose pressure over time - sometimes does, sometimes not depending on the rim. I would definitely use these moving forward...even for races. if they last longer, grip just as well, and are cheaper, I really dont see any reason to go back to the hoosiers. Sorry, want to buy american but not with that big of a value difference! Only issue is that it is not always available so need to plan ahead and order a backup set before you really need them.

These are racing tires. I used them on my IT-C Renault at Mid Ohio two weeks ago and won all three races and set a new track record by over half a second! Their wear seems better than the Hoosiers that I have been using and the price is much better. They are a little heavier than the Hoosier, but not too bad for my class. The pressures and setup are the same.

November 17, 2011

My 2006 Mazda MX-5 (3rd generation Miata) is prepped for C Street Prepared class autocross competition, where I compete against the smaller & much lighter 1st and 2nd gen Miatas. My drivetrain/suspension mods include AST 5220 coilovers, Hyperco springs, Hotchkis RX-8 front swaybar (no rear bar), full polyurethane bushings, and Mazdaspeed LSD. The engine is producing close to 200 hp and 170 tq (crank). It weighed 2360 at Nats this year, or nearly 400 lbs more than my competition. My best finish was 11th in 2010, although the car does have a National Championship title (Juliann Pokorny won the CSP Ladies class in 2009, in the rain on Day 2, on Hoosier Wets).

As a matter of fact, I've never been to Lincoln NE for a National-level event when it didn't rain! This past May, I was there for a 4-day combined SCCA National Tour & ProSolo, and it rained for the Tour. We finished mid-pack on my street Dunlop Direzza Star Specs, so I vowed to be prepared for rain at Nats.

I bought some "insurance" for Lincoln and installed a fresh set of the brand new Hoosier Wet H2O racing rain tire (275/35R18 on Enkei RPF1 18x9.5" 45ET wheels) just before the 2011 Tire Rack SCCA Solo National Championships. I also had a fresh set of Hoosier A6s for my dry race tires. We were in the first heat, and it had rained all night so there was not just standing water, but small rivers flowing across the course. After 1st runs, we were way ahead of our competition, and stayed on the H2Os as everyone else switched from rain tires to dry and back again, trying to find the edge. On my last run, with drying conditions accentuated by standing puddles, I layed down an astonishing run and finished Day 1 in 1st place, .6 seconds ahead of the field (including multi-time National Champions Matt McCabe, Scott Fraser, and eventual winner Tim Aro). I finished in 4th after Day 2 in the dry, so I give all the credit to the fantastic Hoosier Wet H2O tires for helping me achieve my first Nationals trophy!

Project STR races in C Street Prepared at the Solo Nationals

Wednesday, August 31, 2011 by Tire Rack Motorsports
 Following the fun of our R-compound tire test, we thought it would be an interesting experiment to run the car in the C Street Prepared class at the Tire Rack SCCA Solo Championship event in Lincoln, Nebraska. Since our regular drivers can’t compete in more than one class we drafted GRM’s newest editor and long-time Miata owner Alan Cesar to make his first trip to Nationals and drive in CSP. We also twisted the arm of SCCA’s VP of Rally/Solo Howard Duncan to take a turn at the wheel, too. Just to keep things interesting neither driver had an opportunity to practice in the car prior to their first run. To make matters even more challenging, the morning dawned with pouring rain soaking the course.

Alan Cesar runs through a soaked courseThe rain stopped as runs got underway, with plenty of water still on the course. All the competitors had bolted on their racing rain tires, so we rolled up our STR “wet” tires of choice, the Dunlop Direzza Sport Z1 Star Spec. Conditions continued to dry out so we installed the Hoosier A6 radials for the 2nd and 3rd runs, figuring it was going to all come down to the final run, anyway.

Alan was the first driver, and had to live with lingering damp and puddles, which made driving at the limit on the virtually-slick Hoosiers a real challenge. A spin and several big slides on his first two runs left Alan playing it safe to get a clean run in the bank heading into day 2. Duncan took maximum advantage of a rerun and the continually improving conditions to lay down the 6th fastest time of the class!

Day two was a different story, with warm, humid and most importantly dry conditions. Alan adapted to the sticky Hoosiers, showing no fear as he attacked the course. Cone trouble on his first two runs again forced Alan into safe mode to get a good one in the books. Howard is no stranger to R-compound tires, also driving hard right out of the gate. His scratch times were solid, but cone trouble penalties on all three runs pushed Howard down to 11th spot, just out of the trophies.

The car showed good speed in CSP, despite the relatively mild prep level (for the STR class). It would be an interesting experiment to d a little more development and try the car in CSP. Hmmm. Back to the matters at hand, the next stop for Project STR during Nationals week in Lincoln is in the Street Tire Roadster class with project drivers Chris Harvey and John Rogers at the wheel. 

At the Track with Hoosier Tires

Wednesday, August 17, 2011 by Tire Rack Team

Hoosier A6The A6 Radial from Hoosier is a Dry Racetrack & Autocross Only tire developed for drivers who compete in autocross, time trial and hillclimb events in dry conditions where responsiveness and high levels of grip are desirable. This particular Hoosier tire begins with a tread depth of 4.5/32" and does not require shaving for competition. However, it will benefit from a minimal scuff-in prior to its first run. It is important to note that Hoosier Racing Tires meet Department of Transportation requirements for marking and performance only and are not intended for highway use.

We tackle installing an aftermarket limited slip differential to help solve our wheelspin issues.

Monday, August 1, 2011 by Tire Rack Motorsports
As we look through our comments in the log book, one that stands out is rear wheel spin as we try to accelerate to the next corner. We’ve worked on the KW coil-over suspension to try and increase rear end grip, and even tried different tires, settling on the Hankook Ventus R-S3. And while this has helped, at most event sites we can still slide the rear exiting medium to high speed corners, resulting in sideways motion without forward progress. A look at the data stream from our onboard Race Technology data logger shows the OE Mazda diff still allows some single wheel spin, and we’re getting inside wheelspin and not just sliding both rears.

So we turned to the guys at OS Giken, makers of some tricky driveline parts and the OS Super Lock LSD. This tunable limited slip diff allows the rear end to lock smoothly with power application, and can be tuned to have different lock rates during acceleration and deceleration.

To simplify our installation and allow us the opportunity to try some back to back testing, we sourced a separate diff carrier to install the Giken unit in. This allowed us to simply swap out the pre-loaded diff housing in about 2.5 hours, with the help of a co-worker’s lift. Some things shouldn’t be done on the garage floor.

Project STR waits for another turn at the Windy City Miata Club eventAfter a few break in miles, Project STR driver Chris Harvey joined the fun with the Windy City Miata Club to get an initial read on how the freshly installed OS Giken limited slip differential works. The competitors enjoyed great courses and lots of runs as they battled to reduce time throughout the day. Chris piloted the Project STR MX5 to the quickest time of the day for all Mazda's entered and 2nd overall for the event, just a few tenths behind a well prepped and driven BMW M3 running on ultra-grippy Hoosier autocross tires.

Next up for Project STR will be the SCCA Great Lakes Division Championship event held at Grissom AFB in Peru, IN, August 6th and 7th.

Project STR Competes in 4 Events in 3 Weeks

Tuesday, June 7, 2011 by Tire Rack Motorsports
It's been a busy few weeks for Project STR as the summer race season has finally made its way to the Midwest with three back-to-back weekends of competition.

First up was an outing to the Tri-State Sports Car Club event at the Sears Centre in Hoffman Estates, IL for a shake down on the installation of our new KW Clubsport suspension. Coil Spring rubs against the shock body creating a bind in the suspensio ntravel.Installation went well, but during the event driver Chris Harvey noticed some unusual handling characteristics. Investigation revealed that machining on one of the prototype rear shock mounts allowed the spring coils to come in contact with the shock body, creating a significant bind. Once back home, shimming the angle of the top mount canted the spring enough to clear the shock body, and solved the problem. We’re using the first prototype, so the final production piece will be corrected to prevent this from happening.

The KW Clubsport suspension was put to the ultimate test over the Memorial Day weekend as Harvey and co-driver John Rogers drove the car 600 miles to Lincoln, NE for the Tire Rack SCCA Spring Double Nationals with back-to-back Pro Solo and National Tour events. At the Pro, Rogers was quick early on, but faded on day two, slipping back to 7th, one out of the trophies. Harvey was able to capitalize on his day-two runs, jumping up to the 3rd spot, right behind the S2000s of Robert Thorne and James Yom.

Here’s a video look at the right side course on day two.     

Chris Harvey makes a rear shock adjustment on our new KW Clubsport Coil-Over suspensionAt the National Tour event, rain was the story on day one, as the first two heats were run in soaked to just wet conditions. A drying course for our heat meant it would come down to the third and final run to get it done. Adding to the challenge was the sheer size of the course, lasting 75 seconds per run and covering the entire area normally devoted to two courses. Rogers struggled to find his rhythm in several of the four long slaloms on the course, slotting into the 16th spot out of 26 drivers. Harvey fared better, posting the 7th fastest time in the class, and the quickest for a 3rd gen Mazda MX-5 as the field tried to chase down the gaggle of Honda S2000s that lead the pack. Hot temperatures and high winds greeted our drivers on day two. In the end, our team wasn’t able to find enough speed to catch the leaders, with Harvey taking the 8th and final trophy spot and Rogers moving up one to 15th overall.

Back home in Indiana, Chris Harvey took some time to compete in the 19th annual Yokohama/Tire Rack/Windy City BMW Club Charity Challenge held at the Tire Rack test track. All non-BMWs are lumped together in the “everything else” class competing heads up with no index factor. Harvey put his local track knowledge to good use as he drove his way through the tight and tricky course set-up by the Windy City crew. When the dust settled Chris had the 3rd fastest non-BMW and the 4th fastest time of the event. Not too bad considering the cars ahead of him were rolling on sticky Hoosier R-compound tires, versus the Hankook Ventus R-S3 street tires currently on our MX-5.

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

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."

Looking for Your Next Set of R Compound Track Tires?

Wednesday, July 21, 2010 by Chad Hocker
Hoosier Racing TiresTire Rack is a Hoosier Tire Dealer offering the Hoosier R6 in over 50 sizes from 13-inch up to 19-inch.  The Hoosier R6 comes with 4.5/32 tread depth, so no tire shaving is needed. A quick heat cycle by Tire Rack would benefit the R6. Heat cycling can be added at time of check out at $15 each.

Take a look at some of the recent user reviews on the R6.

"I've used these on my Porsche 968 race car in PRC racing and open track days for years, and have always loved them. They hook-up very well, the steering response is nice, and the tire is very predictable. The optimum tire pressures are easy to figure out, and I've found they work well after a lap or two warm up all the way to the end. Overall, a real nice reliable track tire with good stick." -- Tire Rack Consumer Review, Porsche 968, CA

A good reminder on mounting these tires. They need at least 36-48 hours to cure once mounted on your track wheels. If you order just tires make sure you allow for enough time to let the tire cure on the wheel after installation.

Lightweight, Track-Proven Wheels

Saturday, July 10, 2010 by Jim Holloman
So you’ll be doing some autocrossing or track days and you’re looking for some lightweight wheels for your BMW 3 Series or Mazda.

Take a look at the Kosei K1 Racing or the Enkei RPF1. Both of these wheels will reduce unsprung weight and make your car stop faster and accelerate quicker. Both are goals of every track and autocross racer.

Next Generation Motorsports is just one of numerous teams running the K1 Racing wheel from Tire Rack. The BMW 330i (shown here) looks really good with the orange and white paint scheme but is also a true race car. With a wheel that can hold up to track abuse of Pro Racing you know it is going to hold up to whatever comes your way on the street.
 
Match them with some R compound tires from BFGoodrich or Hoosier and you are ready to go. If you are not quite ready for the R compounds, a set of Bridgestone Potenza RE-11 tires will do the trick for track and street.
