Tire Rack Heat Cycled Tires

[22BMWPiloti]

Has anyone bought tires from the Tire Rack and had them heat cycled by the Tire Rack prior to shipping. It sounds like a good idea due to limited track opportunities to break in new tires. I would be purchasing Hoosier R6's. I appreciate answers to previous questions on this forum; racers helping racers.

I have once, but honestly can't say if they lasted any longer because of it.

I buy all my hoosiers from tire rack (im friends with a distributor so i get a good price) and i always get them heat cyled. I have never run on a hoosier not heat cycled so i cant truley compare, yet i hear of many high budget teams getting a new set every 2 weekends, I on the otherhand ran my last set for 8 events last season and am gonna use them for a the first few events this season!

I believe that they use a machine to cycle the tires. the machine gradually adds pressure to increase heat and then the tires are shipped. by the time they arrive they are fully cured and ready to go. I like this because no tread is lost by taking them out for a heat cycle on the track, and like i said i believe they really do last a good while

but again i have never tried the alternative.

I bought a set of 710's, had them done, at the price, I felt it could not hurt.
And I cannot afford to juggle three or more sets to heat cycle on track.
I EXPECTED THE kUMHOS TO WEAR QUICKLY, BUT HAVE 8 HOURS OF TRACK TIME ON THEM, AND STILL HAVE TREAD LINES.
of course, I rotate constantly.

heat cycling has nothing to do with tread life. it cures the tread material so that it theoretically keeps it's grip longer.

race tires are dead long before the tread is gone. hoosier r6's seem to be good for about 8 heat cycles (not weekends) before they noticably fall off in grip. after a dozen cycles, they have lots of tread left, but aren't even worth practiciing on.

ymmv...

Yes not about physical wear, But.

How many heat cycles are those same R6s good for if you start their life by qualifying hard and racing hard on them, rather than just heating up and letting them 'rest' for 24hrs (or 2 weeks if you can)? More importantly, can the mechanism at play really be duplicated by loading the tires on a rig, rather than exposing them to some good old fasioned slip angle?
