    Truck Tire Air Pressure

    Just put a new set of tires in my truck. Had a leveling kit installed so went with bigger tires. They are 35x12.50x20. What air pressure should I be running? I know on the sidewall it says up to 80psi cold, but I know it’d ride like an old logging truck if I put that much.

    Open your door and read the tag on proper psi for truck

      Mine call for 80 and I run 60 until I load it down, then I bump up the pressure. Not the same size tire though. Hopefully you got a front alignment done after the lift, if not do it now.

        The tag on the inside of door is for the stock tires. These new ones are bigger.

          Yes an alignment was done.

            That only applies if you want to use the truck to its capacity.

              What kind of truck ie: make/model, and what is it primarily being used for?

              Model and use is more important than the make, but others might have done the same to a similar truck and can offer first hand advice.

                It doesn't apply at all if you change the tires.

                  I typically run all my trucks at 40 unless I’m loading them down. 55-60 towing/hauling normal 5-10K loads with minimal weight applied to the truck. 10K+ with a gooseneck and I’m running the recommended 80 psi. 60+ rides like a tank with an unloaded truck.

                    Still want to run the recommended (sidewall not truck) psi to maintain capacity

                          Hell, I have two of those. A 2014 and a stock 2022.

                          My 2014 is leveled and running E range tires. I never put more than 50 in them, 39 is the recommended minimum pressure. The first set of Cooper STT Pro’s I put on it got a little over 67k out of them. They were a bit rough when I had them changed, but they could’ve hit 70k if I wanted.

                          Keep them balanced and rotated every 4K-ish miles and run them at 45-50 PSI, unless towing a heavier load. You should be fine.

                            39 for me. No and/or limited towing

                              I run 20s on my 2500HD and I keep my tires at 65-70. Ride is smooth
