I run 40psi in mine with Racestar 15x3.75 with Nexen 165/80's. My tires say max of 36psi. Tires don't ride, look, or feel any different then they did at 35psi.

No matter what brand I used to always run 45 psi on my '77 Camaro. I ran 165/r-15's on 15 x 3.5 Cragar Superlite II's. Only once did I have a bubble on the tire, but that was from a manufacturer defect. Got that replaced quick before I had a blowout.

It depends on how much weight you put on them. If you look at that 37 psi on the sidewall it should say 37@x-amount of lbs. I have a v8 87 rx7 and i run 35 psi.

I think its 37psi at 1250lb

Now take what ever your front of your car weighs and do the math. At 37lbs it will carry 2500 with 2 tires. If your car weighs lets say 2000 lbs in the front then you would be safe around 34-35psi.
