i know that i shouldnt run Sumitomo's on the track, but they are already on the car and i decided to do a track day tomorrow...what tire pressure should i run in them on the track ??

thanks for any advice

 

My street tires increased +6psi during 20 min. session from cold to hot.

 

One member (JCB-Memphis) recommended 32F and 35R cold, 38F and 41R hot. Been using the same tires at the track in the past, and going to try these pressures this weekend at Buttonwillow where the temps are supposed to be 102 degrees. Been experimenting myself with different tire pressures. Will see how it goes.
