Tire Rack Heat Cycled Tires

[seckerich]

Telemetry shows about .2 G's more grip with first few laps on stickers. They will give up after that and get greasy for a few and come back. Stickers that are raced first heat cycle will never maintain the same level of grip after they cool. I tend to trust the actual data rather than guess. This is on a 2680# Mazda. You might get away with it on lighter cars.

Thanks for all the feed back, sounds like the on track break in is still probably the most preferred.

If you talk to a Hoosier Engineer about "other companies" heat cycling procedures you get that strange look with a dissatisfied grin.......
