35 lbs is standard on that combo. I have the same ones.

 

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

 

Instead of going to the deal you could just pick up a phone and call.

 

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.

 

I have the very same tires and wheel size oem on my truck, 35 psi for all 4 wheels is on the door.

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.

 

The pressure listed on the tire is the max it can handle, not the pressure you should inflate it to!

Plus do a test at 40-44psi compared to 30-35psi... you'll see that the ride will get extra bumpy and rough!!!!

My Eagle LS2 came at 44psi when I purchased the truck, the ride was bad and rough.... until I noticed the sticker on the door said 30psi... lowered the pressure in the tires and wow...what a difference...

thats exactly right. the psi listed on the tire is the max or pressure. just trying to let everyone know that some tires (especially truck tires) have a minimum pressure as well. so you cant go by the door every time.

 

[the psi listed on the tire is the max or pressure.

Now here's a related question, are those max pressures max hot or max cold? :ugeek:

It doesn't matter if it's hot or cold. It's still above what it can handle.

Don't think you're getting it. Let's say the marked max is 44, checked in the morning when it's 60F outside (cool). A few hours later and some driving the tire pressure reads 48. So if it were 44 max cold, it would allow for some heat range, if it was 44 max hot they should inflated to no more than 38-40 and should be labled as such. But it just makes me question as it appears some people set their pressures pretty high.

Mine have so far never increased more than 3 while in use but it really depends on the tire how much that will vary.

 

@ Gorecki

It's not the tire manufacturer's concern to determine what "your" weather and driving conditions are. The max this tire can operate safely is 44PSI. The owner needs to be responsible for his/her driving conditions.
