Help on proper tire pressure for 245/45ZR/17
 

Called America's Tire Co. and guy said should be 35 Psi. Does anyone know what the proper tire pressure is for Raptor Riken 245x45x17?

Thanks!

Tire pressure is mainly based on weight. And it is clearly marked in side the drivers door sill. you may as an option increase that designated psi by 1 or 2 lbs if you like.

Its on the sidewall on all tires isnt it?

Re: Help on proper tire pressure for 245/45ZR/17
 

^no. the sidewalls tell you the MAXIMUM pressure allowed to safely operate the tire.

our pressure is somewhere along the lines of 30-32psi

^^^^^^^ that is correct... just run 33 or 34 with a tire like that running 32 might be a little to soft and then you run the risk of a nice blowout off a pot-hole well actually reguardless a tire like that will suffer from anything but smooth ass roads. good luck

i like 35 psi in the summer its not too harsh. in winter tho everything is very stiff.
