Up to temp/grip in two corners... They jump from 26 psi cold to 31-32psi hot on the first run of the day. they are very easy to heat cycle compared to my hankook mediums which were like blocks of wood until the end of the first lap - 245*40*18 are my size.

Speak with John Fowler mate, he can answer any questions you have about tyres.
