Tire pressure when towing

c5hd · October 21, 2003

I have a 2003 2500HD CC D/A. I am towing a 20' race trailer and Corvette. They way about 7000lbs. I have the stock bridgestone 245x75x16 E load tires?

Any recommendations are appreciated.

Thanks

when towing i set mine at 55ft and 80r. of course depending on the size of yoiu load you wouldnt have to go so high.

I run about 50psi in the front and 60psi in the rear when I know I'm going to do some towing. Otherwise I run about 50 psi all the way around. My 265/75/16 Michelins (load range E) don't seem to require as much air as the stock tires did...

I am running the factory Firestones on my truck and run with 55lbs of pressure in all 4 for everyday use. I run 65lbs in the rear when towing a 5000lb trailer and a full bed of camping gear and fire wood.

I tow a car trailer close to your setup and weight with the same truck. I've experimented a bit with different pressures but usually go with 55 lbs in front and 65 in the rear with the stock tires.

In addition to the weight distributing hitch the thing I've found that makes the biggest difference is a dual cam sway control.

I run 50 in thr front and 70 in the rear. Now that the camping season is winding down, I may decrease the rear ones to soften the ride. I pull a 5200 pound travel trailer.
