Tire Pressures
I was wondering if you guys are running the recommended tire pressures when you're towing or if you're running something different. I'm towing a 10k toy hauler with about a 1k tongue weight. The 1996 Suburban I was towing with was running 80psi in the rear tires, but the X only says 55psi? Should I be upping the pressure in the rear when towing?

look at the weight rating on your tires...I have E rated tires and I pull about the same weight as you..towing I inflate to 70frt / 80rear, unloaded around 50frt / 60rear psi..
you don't want to be underinflated when towing..it heats the tires up and can lead to failure..

I do have E rated tires and that's why I questioned it. The tires say 80psi on the sidewall for the maximum load. I thought the rear end felt a little soft and wallowy, and that's why I asked. Did the X's come with D rated tires as OEM fitment?

Yes they came with D's. I would run the max; 80lbs with that trailer.

I still have my recalled tires on it. They were changed every winter to studs.

Do you not use your Excursion often? I went through an entire set (including the spare) with those D rated Firestones. All of them at some point blew out. The E rated Firestones that replaced the recalled ones though were great tires. I got about 65,000 miles out of those with zero flats or blow outs. When I got the recalled tires replaced with the E rated Firestones I got five tires and I still have that fifth tire as my spare which has never been used. Right now I have Pirelli STRs on the Excursion.
