I just picked up 20" wheels with a combo of 245/30/20 front and 275/30/20 rear. I wanted to know what's the tire pressure should be set to? Any help would be appreciated.

I have a 04 coupe sports package.

 

It dpends on preference. I'd say anywhere between 35-40PSI.

 

I would try factory specs at 35...then pay attention to the wearing and adjust accordingly. Such as, I ran 38 in my 245/275 35 19s and the middle was wearing faster than the outsides so i let it out to 35 and now they are wearing evenly again...

Good luck!

 

i have the same setup runing about 30-34 just depends i ran 32 on my first set of wheels lasted forever!

 

Are the tire pressure setting everyone has when the tires are cool? Haven't measured my cool tire temperature for a while, but just checked it hot (after freeway driving) to be 38psi. I'm always paranoid about the tire pressure because the tires look dangerously flat (stretched low profile tires that came with the rims).

 

I stay between 33-35 psi on nitrogen filled depending on the tires. I get very fluctuation in pressure and decent wear.
