I'm running 18" PS4s, 275 in the rear and 235 in the front. What's a good pressure to run? This is my DD with occasional spirited drives, no track. But I do have around 500 rwhp so traction can be difficult at times.

With the stock 245 rear 215 front I was running the 42psi in the rear and 38 in the front, this what the manual recommends for fully loaded 100+ mph.

I figure I should run a bit less pressure to improve straight line traction. I never go over 100mph and rarely do I carry passengers.

Inferred thermometer, read the tire. It will tell you what pressure it wants for the conditions.
