35" tire pressure - Dodge Diesel

chopper698 · 06-08-2012, 04:11 AM

For those that are running 35" on stock
rims what air pressure are you running
unloaded?

I don't run 35s but the tire shop I use to work at , it was policy to inflate over size tires to the same psi as indicated on the door sticker. Justification: tire pressure is based on the best wear for the weight of the vehicle, among other factors. The weight of the vehicle didn't change much. We never had trucks/suv's coming back due to under inflating or over inflating causing the tire to wear out quicker on the sides (under inflate) or down the middle (over inflate). When customers came in for tire rotations, tires always wore evenly. Just my thoughts.

I run my 33"s at 50-55psi in the winter* for better traction and 60-65psi in the summer for better fuel economy, 70psi when towing. They seem to be wearing evenly.

*Just don't forget to air them up to at least 60psi when towing or the EVIC will give you a tire PSI warning message.

65 is the max for my 35"s, I went with
what it says on the inside of the door
60 front 45 rear for light load. I disabled
the TPS through the mini max. I found
it more comfortable with 50lbs in the front.

60/45 here, I like the assistance in turning more air pressure provides. I have 9" wide wheels so I get more tread contact area w road surface and while they will wear the center faster I like the turning ease 60+ psi provides.

At 50lbs just check the sag in the tire by stepping back and looking at them front to back. Not an exact science but good enough for me and my truck.

I believe I ran 55-60 fronts and 40-45 rears on both my E and D rated 35's. On the D rated if I recall correctly it was like almost 60 front and around 40 rear to keep the sag even. Not the right tire for the application though and went with E rated to be proper.

I'd probably stay in the parameters of the pressure listed on the tire and not on the door if you change from factory tires.

I've run the following pressures in every set of MT's I've owned. Unloaded, 45 in the fronts and 35 in the rears. This is on stock wheels. I keep about 300 lbs of playsand in the bed during the winter and air up to 45 in the rear then. I averaged over 65k on every set of MT's so far, and installing my 3rd set next week. It would take a lot for me to consider changing.
