I feel like such an amateur asking this question, but I have a 1995 Dodge Ram 1500 with 5.2L 2wd, with a GVWR of 6400. I put Mastercraft Courser A/T2's on it last November. I noticed the tire was wearing in the middle (overinflation, I know) from the amount of pressure that the shop put in them. I can't go by my door sticker, because it's for a smaller tire. So what pressure do I need to run in these tires? Is there a calculator out there somewhere? Thanks.

 

Start with 35 pounds and adjust as needed, by inspecting tire wear. I run 2 different psi's . Rear less. Front more. I also rotate every oil change.

 

I run 70 lbs in my hankook dynapros

 

I have load e 265/75/16. I haul, tow, and plow. I run 50psi.

 

look on the side of the tire for the max tire pressure and don't exceed that.

load range C can run max psi of 50
load range D can run max psi of 65
load range E can run max psi of 80.

I've got D (max 65). I run about 45 for everyday unloaded driving, and air up to 60-65 if i'm going to haul wood or a heavy *** trailer.

too much psi will give you a light and skatey feeling. i don't like that.

 

I have always went with 36PSI cold. That way it would get to about 40 PSI when they get warm from the friction of the road.

There is a difference in tire pressure after only 60 minutes of driving.
