Hi, I have made use of the search button but couldn`t find nothing useful. What tire pressure would you guys recommend for an autocross event with laps lasting 1:15 - 1:30 (current ambient temp is around 60-70).

The car is almost stock except for whiteline rear subframe inserts. I ve been using the car with the stock primacys for about 7 autox events. On the last two i got great results thanks to a imho optimal tire temp pressure (39F - 37R) hot.

Got two 2nd places and top 30 on over 110 cars. Now, last week i used yokohamas A048 but i didnt feel quiet confident with the rear. The front was great, really inmediate response and pointed towards i wanted to place the car.

The rear on the other hand was all lose. Tire temp pressure at the end of the event was 35F - 31R hot. I am thinking about going to 34F and 28-29R. What do you think?

Thanks a lot in advanced!!
