    Race tyre heat cycles

    Hi Guys, can anyone tell me about tyre durability for a race tyre, how many heat cycles can they go through before they are fucked, Im currently thinking if it isnt worn out its still good but Im not so sure this is correct.
    Can I get some reasonably qualified answers on this please.

    cheers

    Subscribes to this thread !
    A girlfriend once asked " Why is it you seem to prefer to race, than spend time with me ?"
    The answer was simple ! "I'll prolly get bored with racing too, once i've nailed it !"

    Bowls can wait !

    I run supercorsas on the bandit and have noticed when they've had enough they really stop, I mean , just no grip at all ! But that is usually when the tread had almost gone. There is a gradual decline, but when its over you really notice.
    But as far as heat cycles , I do heaps. If that helps at all ? Gaz.

    Proper race tyres are at their peak for one race. Not meeting or series. One single race. That's why you'll see guys picking up track day tyres from racers for next to nothing. They're better than anything Johnny Trackday has used, but for a 10/10ths racer they're shagged.
    If a man is alone in the woods and there isn't a woke Hollywood around to call him racist, is he still white?

    JD has it in a nutshell. If you're racing for fractions of a second then one race they've lost that last 1/100th of grip.
    If you arent finding the limits of the tyres then so their theoretical lifespan increases
    To see a life newly created.To watch it grow and prosper. Isn't that the greatest gift a human being can be given?

    Oh thats nice if you have a factory sponsor package but in the real world the question remians, how many heat cycles are they good for ??

    One. They're only designed to be used once. If you want to use tyres over and over, buy top end sticky road tyres.

    8 to 10 heat cycles maximum. Peter Goddard describes it very well, ''tyres are like cakes'' Dont heat them beyond 75 degrees max on your warmers otherwise you will change their chemical composition. Dont let them cool down too quickly after a race / practice, place the warmers back on them to let them cool down slowly.

    Are heat cycles counted each time you take the warmers off or per day?


    My pirelli superbike slicks seem to last forever. Maybe I'm doing something wrong?

    6 to 8 is about the sensible limit for good behaviour, anything more than that can end up with poor grip, and worsening predictibility. This relies on the heat up and cool down being well controlled - warmers back on to cool the tyre down slowly. Most 'race ' tyres suck real quickly if you don't look after them, although some are worse behaved than others.
    The best behaviour a Race tyre (treaded or not) will ever do is the first hot one straight off warmers. Anything after that is second best, and the fast guys can pick a tyre that has been cycled more than a couple of times.
