What is your tire pressure?
I have 20's 245/35/20 front 275/30/20 rears and currently running anywhere between 34 to 37 psi. I feel that's too low but the shop that installed my rims put them to that pressure... Is that a good tire pressure? I would think I should be between 40 to 45... Thoughts??

Thanks for your input... I kinda feel the steering wheel a bit heavy that's why I feel the pressure is low. I am going to see what the door and tires say.

During the spring and summer it is typical for the tire pressure to increase 6 psi or more from overnight 'cold' pressure. The day's temperature warms up 20° (≥2 psi), plus driving on them (≥2 psi), and the sun's radiation heats them up (≥2 psi) can easily add up to 6 psi or more.
I cannot imagine why anyone would set their tire pressure when 'cold' so high that the tire pressure would reach 40 psi or higher at peak.

I really cannot imagine why the recommended cold tire pressure would be that high. The tires must give a nice boing sound every time it runs over the tiniest crack.

Now you disagree with the engineers who designed and built the car.....it's a line you have stood firmly on in the past
