The key to the heat cycling process, whether it be on a car or a machine (like we do also), is that the tire is allowed to cool SLOWLY to ambient temperature. We cover all our heat cycled tires with thermal blankets so that they slowly cool to ambient temp before they are shipped. The reason we have such great success with our heat cycled tires.

Based upon my experiences at Palm Beach, I found that SM7s did not fall off during a race like the SM6s did.

 

I did an initial heat cycle during warm up on Saturday by scrubbing (back and forth) the tires at relatively slow speed and intermittently braking hard to raise temps. I ran faster and faster laps (about 8/10s) for about 4 laps and 1 lap at 9/10s and stopped and put the tires away until Sunday (24 hours). Danny Steyn and Forrest Landy also did this so they can report their experiences.

 

During the Sunday 40 minute race, the tires held their grip much better than my experience with SM6s. This was particularly good because the Palm Beach track usually eats tires up fast. I look forward to using the SM7s the rest of the year.

 

Sebring's Sunday race only had a few hot laps (see forum posts and videos elsewhere) and I used those tires for the Saturday Palm Beach (30 Minute) race because they had cured all week. They held up OK but still fell off a bit more than I thought the SM7s did during the 40 minute race the next day. Also, FWIW, I pushed the tires harder Sunday because I ran faster.
