If you run 80 psi with an empty bed you will wear your tires in the middle and have unsafe handling. In my diesel F350's with utility beds and a full complement of tools and parts I run about 60 psi in the rear and 50 in the front with load range E tires. At about 8500 lbs total weight this seems to give good tire wear and as good a ride as can be expected from an F350 4x4. If I am going to get a load of firewood or something heavy I will air up the rears to 80 psi for the duration, then back to 60 psi. I have never found much reason to vary the pressure in the front tires as the pretty much carry a constant load. Aklim- I don't know how you can stand 80 psi all the way around in an Excursion!! On mine I go 50 all the way around and it still bounces on the slightest bump. You must have smooth roads where you live!
