I have 18's on my car... what how much psi should I be running?

 

What size/make/model of tires?

Generally inflation should be around 32-34 psi, even with non-OEM tire wheel combos, but not sure if your setup has any special issues involved.

 

Should say on ur tires...

 

Actually, tires show the MAXIMUM pressure, not the recommended driving pressure.

 

it depends on the type of tire....


max psi on my nitto's are 42.lb

I have my front tires at 33psi and my rears at 34

 

i wouldn't put 34 on the rears...the rear part of the maximas on a bumpy road(cities) is the worst part. the suspension is just way too harsh back there and you i think that its better if you don't go over 30PSI in the rears
i put 33 on the fronts and 30 on the rears
