Just curious what's working for everyone with these tires on track. @Moto and I ran 38-38.5 hot as Sonoma last week. @Black Boss was running 39-40 with his and @JAJ has been running 34. Last Friday at Thunderhill it got up into the low 90's and the tires still felt good at 38 hot. These tires are pretty grippy but after two days I'm not sure I'll get more than four days out of a set.
