Correct Tire Pressure?

Correct Tire Pressure?

Postby Mr. Horsepower [OP] » Dec 22 2011, 7:15pm

Hi there. I recently purchased a 2011 Silverado and decided to change out the stock 20" rims with some 18" Z71 rims (not a big fan of chrome, but it was the only one the dealer had on the lot :D ).

The problem is, I'm not sure what the correct tire pressure should be on the new tires. Obviously I can't go by the door sticker because it's set for the stock 20's. Does anyone know where I can find this information? The tires are Bridgestone Dueler AT's 265/65/18. I've currently got the front at 35 cold and the rear at 33.

Thanks in advance!

Go to a dealer and check what pressure they recommend for the 18" wheels and those tires....


My 20" require 30psi, my spare in 17" require 35psi

call the tire company. most tires will have their own pressure guide lines. if you know the weight of your truck they can tell you the exact pressure you should be running.

for example the Michelin's i have, state that with my truck they need to be at a minimum of 40psi.

Ditto, ditto. Dealer puts them at 35 all the way around though they did ship with 33 in the rear for some reason. :?

Thanks for all the replies. Puts my mind at ease knowing I'm not burning those tires up too quickly

Go with what's written on the sidewall of your tire. Consider your driving condition, how far is your commute and if you are towing or not. Mine says 50PSI max. I don't tow, weather her is in the 60's to 70's. And I don't drive more than 15 miles to work. I keep my tires about 42PSI. It handles better, body doesn't roll as much and it saves a little bit of gas i guess.

again go with what the tire manufacturer says, the door sticker is listing the stock factory tire specifications and recommendations.

yes 35psi is good for most tires but play it safe, you just invested hundreds of dollars into them why not do what the tire builder says to get the most miles possible.
