Safe Tire Pressure Questions
My 2008 truck has a GRAWR of 6,084 lbs, and the front and back tire size is LT265/70R17 E (3195lbs). The door sticker states tire pressure should be 72 lbs on the rear. I weighed the truck and trailer the other day and my rear axel weight was 5610 lbs, or 2,805 lbs per tire. According to the Bridgestone tire guide:
3005 lbs = 70 PSI
3100 lbs = 75 PSI
3195 lbs = 80 PSI
So, being that I try to keep my Maxxis trailer tires set at 80 PSI (per Maxxis) I thought I should keep the rear truck tires at 80 PSI as well (which is the max PSI for the tire).
Being that at 5610 lbs I'm under the max tire weight (2,805 lbs/tire) and under the GRAWR am I safe using the 72 PSI recommended by the GM sticker, or would I be better off going to 75 or 80 PSI?
I want to avoid tire problems, therefore I would appreciate your thoughts.
