Do Toyo Proxes RA-1 race tires need to be heat cycled?

I was told that after you shave them, they do not need to be heat cycled like Hoosiers and Kumho's do. Is this true? If so...does anyone know why?

Thanks!

According to AIM who sellls all the RA1s at Infineon, and supplies 80% of the NASA road racers in NorCal, RA1s do not benefit particularly from heat cycling. Carl

They do not benefit as greatly from a heat cycle, because they are much more durable than a hoosier or Kumho. They are good until you hit the very hard rubber right be fore they cord. These are very economical and long lasting tires*..


*The Spec Pinata boys are starting to complain and it seems that Toyo might have had a bad batch as Rumor suggests the wear rates incresed substantially late in the year. This was not proven out during the 25 hours of Thunderhill...
YMMV,

Welllllllllllllllll...............

I still believe in heat cycling - including Toyos. Rumor has it that in many cases the shaving creates enough heat to do this, so it's kind of a two for one. I've seen a couple differenct types of shaving. One that looks like the tire was cut, or almost like it was turned on a lathe. On the other it looked like it had been run on a grinder. Either way, it seems like that would probably do the trick as far as heat cycling goes.

I wouldn't particularly recommend putting on a brand new set of shave tires and going and running a 6 hour enduro, but you don't need to do the 2-hard-laps-then-pit routine that you do with other "race" tires. One thing to keep in mind is that the Toyo's do drop off after so many heat cycles, but I don't have much of a problem with my tires that have an 01 date stamp on them...
