I asked a friend once about tire pressures when towing and empty. He told me that to find the correct pressure for my vehicle and trailers as to set the pressure at the suggested amount, take some chalk and mark a line across the tread , then drive a short way. If the chalk wore off in the centre, then reduce pressure, if it wore off the edges add more. If it wore evenly across the tread, then that was the correct pressure.

Thanks everyone for all the replies. My truck calls for 60 in the front and 80 in the rear. I guess that is what I will run. Happy camping all!

My OnStar tell me when every month when my GMC 2500 tire pressure is off. They tell me 75 front & 80 rear and that's what I follow.

Rubbernail what tires do you have that can take 85psi? You should never go over maximum on the sidewall.

Tire issues

I am glad you read the tire sticker in the door jam to see that pick ups have a different pressure for ft and rear. No you should NOT run the same pressure when towing (unless the trailer is that light to you truck it does not matter) BUT VERY FEW DO THIS, so you are correct you run a higher amount in the rears when towing, Most gm. models are 50/55 fronts, and 80 rears. Now if you are towing a tag type trailer you might need to adjust the rear tire pressure as the tough weight might not need to much, but only time and driving will tell you that.

And yes you need to then take the air out when you are not towing for a length of time (the center of the tire will wear out quickly) and then just air them back up when you need to tow again.

Hope this helps you out and Happy Camping

When I had my older 2001, 3/4 Ton Chevy before TPMS was mandated on vehicles less than 8,000 LB. You were always told to run the front tires at one pressure level reading and the rear with no payload or trailer towing at lower setting (nothing less than 45 PSI). You were than instructed to raise the air pressure to a higher setting when loaded to support the load.

Now with my 2008 Ram 3/4 ton diesel truck; I am using Nitto Dura Grappler tires (126R rating) and the front is set to 50 PSI all of the time and the rear are either 50 or set to 70 PSI depending on the load. I have also removed the TPMS senders in the wheels and tires. Don't tell big brother!

My 2011 F250 calls for 60 psi in front and 70 psi in the rear and that is what I put in them.

My '15 F250 calls for 65 all around, and I use that when not towing or towing very short distances. On long towing trips, I run max cold pressure (80) all around.
