what PSI in tires?

Odd question I know - but I have 305/50 x 20" tires and was wondering if the proper PSI is 32? I have to admit I have NEVER checked, added or removed air from my tires in 18K miles. I run the factory 18s in the Winter. Any help would be appreciated.

it is different with every make/model of tire. It should say right on the side-wall. My toyo open countries are maxed out at 40psi where as my buddy has toyo m/ts and they max out at 50psi. Check your tires and if you still have trouble, take your rig to your local lube shop. Be nice, they'll help you out.
good luck.

thanks for tip - I always thought the sidewall number was MAX pressure.

just remember to keep all tires at the same psi. max psi is ideal for regular driving. If you live above 3000 ft, check your tire pressure more often.

The side wall listing is the max pressure, don't run that. It is not the ideal pressure. 35-38 is a good starting point. Check with the maker of your tires for the proper pressure.

I have been misinformed and in turn I have misinformed. For this I am sorry>

I run 40psi in my Nitto terra grappler 305/50/20's. If you air them up you will decrease rolling resistance, but not too much because you'll cause improper wear.

They are supposed to be run at 39PSI according to Discount Tire. Larger rims = higher pressures to stop rim damage. The makers design the tires to wear at these pressures so if you run them light you will have poor wear and be buying loads of extra tires. MAX pressure is for towing Max loads. This keeps the tires inflated instead of squished under heavy loads.
