How much pressure (PSI) should I run in these tires?
#48
My 01 Ex v10 2wd GVWR is 8600lbs. GAWR Front is 4600lbs, GAWR Rear is 5250 lbs.
5250-4600 = 1250 tongue weight.
I could be be wrong Brent, but I think it's heavier in the front. Now don't tell me the 4x4 diesel is heavier in the rear.
Disclaimer: If I am wrong Brent, this is the first time I am wrong in my entire life.

Or you could NOT ignore all of the science and calculations of the numerous engineers who actually have some background in this. If 60-70 PSI were needed then that's what would have been put on the door sticker that the truck and tire manufacturers are legally responsible for.
My '07 Kenworth work truck I used to have was fitted with 275/85R22.5 tires, and those needed 100 PSI to support the 12,000 lb front axle. No reason in the world an Excursion needs 70% of that pressure to support a 4,000 lb axle.
That's just wrong, bud.
You are wrong.

I tow fairly often and don't want to worry about having enough air when I hitch up. Therefore, I run 80 psig rear and 75 psig front nearly all the time. If it is icy/snowy out, I'll reduce pressures to 65 psig all around just to get a slightly bigger tire patch down.
I really don't mind this truck riding like a truck. I'm not concerned whether the air pressure is too high. I've never experienced abnormal center wear with Michelins (I just installed my 2nd set on 2005, had 3 sets on 2003).

@Tom, the fulcrum determines the weight distribution.
A little off topic, but an Excursion is not a truck. It's an SUV that rides like a truck. Rough and uncomfortable. If you're not careful kids spill their drinks when going over bumps and potholes. Or you spill hot coffee, whiskey, jack daniel's, vodka on your lap. Waste of good booze, "UNACCEPTABLE!!"
I wonder how many F250 owners with camper-shell call their truck an Excursion. At least they can take off the camper-shell and hook up 5th wheel, haul manure, and other big items that don't fit in the Excursion(oops, truck.)
Try hauling manure in the Ex and then take your 7 wives (8 wives if you have the 9 seater) to dinner. I bet they'll divorce you and get with the F250 guy with the camper-shell. Of course they will have sit on each other's lap because the crew cab can seat only 5 and surely you don't want any of them to sit on the goose neck hitch. Or maybe you do want them to sit on the goose neck hitch. After all, you don't mind the rough ride.
Back on topic, OP just do the chalk test for optimal wear and ride comfort.

Yup, and the axles are the fulcrums.
I'm gonna quote Art:
Of course this isn't one of those times.
