Correct Tire pressure 35 and 45 profile

Coldduk · 11-13-2006, 02:07 AM

I know I should know this but with $200 tires I want to be sure. The tires say max psi 50lbs but the yshould run between 32-35 psi right? Thanks guys.

In the owner's manual, it says that for factory approved tires it should be 30 psi for the front and 35 psi for the rear.

when you open your drivers door it has the tire sizes and whether its a winter or summer tire and the pressures for the front and back, I believe for 15" it says 29psi for front and 32 for the back, just check it out either there and in the owners manual as said already

If you really wanna find out... Go get a crayon or grease pen and draw a line across each tire... Inflate to 35 psi and drive it for a bit... If the line wears off evenly then there yea go.. If the center wears out first let air out... If the outside wears off first then inflate...

Do that till you get even wear and you will have the correct air pressure for each tire...

Very cool! Thanks for that...

And yes, 32-35 is ideal.
