Tire Inflation

LWP427 · May 18, 2012

When i was taking delivery of my R/T i noted the in dash tire inflation was 39 front and 42 rear. I asked about that being so high and was told that is what the factory recommends. The truck was cold and not driven.

I looked on the door post and it says proper inflation is 35 PSI front and rear.

Anybody have any recommendations? The wheel and tires are stock 22"

Thanks, Larry

id go with what the recommendations on the tire or on the door say, but look on the tire for what it says

Don't they normally run the psi high from factory for a break in period on the tires. And then you're supposed to drop it down?

Wrong. Sidewall says max psi. Don't run max unless you need to (like towing). Door jam is where you need to look (for everyday driving and normal conditions). Service techs are suppose to adjust pressure upon you buying the vehicle.

i run 42 in my stock 20's all the way around. it rides smoother and wears better in my opinion

Mine had 40+ in them when I brought it home from dealer. Set it at 34 - 35 all around. 40 psi is just too high on stock tires IMO
