ok, i've got 18" x 7.5 rims with 245/45/r18 tires
my tire pressure reads 29psi and the tire says it can take 50psi
the pressure in all of the tires are the same so i'm guessing that the place that did it set them at 29-30psi
my question is this... What psi should i put them at and still have it safe (50psi sounds like way too much)

 

anyone?

The general rule is +1psi for each +1 size. I'm doing this from memory so double check my stock numbers (inside the armrest). On stock 15" rims it's 33 psi front and 32 psi rear, so with 18" rims you'd want 36 psi front and 35 psi rear.
