Tires heat cycled out
I'm running my first set of R comp tires, 315/30/18 nitto NT01s. I have 8 track days on these tires, there is still tread life remaining on them. At Laguna on Saturday towards the end of the day the tires were losing grip. The last two sessions started off fine but around half way through the grip was noticeably declining.
My question is, is that the telltale sign a tire has heat cycled out? Or was the decline in grip a product of the track? Temps? Air pressure? It was about 80 degrees, tire temps about 180-190 after the session. Is it time to swap these out? |

NT01's are known to heat cycle before they cord.
