I think it is either 35 or 36 all the way around.

EDIT: just went outside and looked real quick - it's 36.

 

That's what I thought but they looked slightly underinflated.
Thanks LTrain:thumbsup:

 

They handle/wear better at 38-40 psi, I prefer 40. Factory runs them at 36 because most people are whiners who find properly inflated tires to be too bumpy of a ride.

 

I was having the shimmy problem, so the dealer was working on that issue...when I got the truck back, they were all set to 38. Prior to that it had been set to 36 since day1.

 

Gentlemen

Wanted to dig up this old thread

My stock 20" Forteras..... what is your subzero winter PSI ? I am at 34 right now (yes I know that is too low) and I am going air them up today

Thinking up to 38

My Jeep dealer recommended cold (undriven) pressure of 40psi with the current daytime temps in the teens to 20's Farenheit.

 

I just set mine to 38 last night

Holy delay on our tire pressure sensors !

 

Reminds me to air mine up, I noticed mine dropped to 29 in the cold NY air.
