This is the first time with a set of these M/T 275/60/15 ET Streets S/S. They are on a GMC S-15 with a 377 Hyd Roller stroker motor with a glide and a 3.70 Ford 9 inch. What is a good air pressure to run them at. I have them at 15 psi. now and as the sun hits them the psi. will go up.

Here is Mickey Thompsons ballpark suggestions. If you scroll down it shows they recommend 1# change at a time with radials.

I found more is better. I run 18 with my 27.5 " 255 60 x 15 ET R. my car weighs 3500 with me in it running mid 12s w a 1.8, 60 . That is at my track in cooler weather.

I forgot . You need to check and adjust in the staging lanes.
