I rotate every 5K miles and run front and back at 80psi. I have been doing this for the last 18 years with this truck with zero problems. I tried once with 65psi in the front and it was kind of sloppy going down the freeway.

Rig: 2006 GMC 2500HD with 2001 Lance 845 camper. Tires are Michelin LT265/75R16.

My door jam plate says:
Front 53 psi
Rear 80 psi

I have been airing up to:
Front 60 psi
Rear 80 psi

My axle weights with camper and loaded for long term travel are:
Front 3350 lb
Rear 5800 lb

That's just under my GVWR of 9200 lb.

Last summer I had my tires rotated when traveling and the shop said I had wear on the front (cupping IIRC) indicating not enough pressure. So they boosted the front to 70 psi (or more).

I'm getting ready to hit the road again for several months. What is the consensus on proper front tire pressure?

Thanks,
According to these numbers you have more than enough air in the tires . My 03 diesel calls for 60psi with 245's . With 265's they only need 50psi for the same weight. Something else is causing the cupping . It could be the roads , front end wear / alignment , or even just the nature of the particular tires .

I agree cupping could be tires. I changed my fronts (stock size 19.5 225) from Hankook DH01s to Bridgestone M724Fs and no more cupping even though I’ve used the Bridgestones longer. No alignment or additional shock changes either.

BTW, the Bridgestones are also all position whereas the Hankooks were drive tires. My SRW also cupped the Hankook DH01s in 245 size. Not a huge problem since I still had 40K on them when I traded, but I switched to the Bridgestones because we were doing a lot more highway driving. I just saved the Hankooks for spares that I took off the F450.

Tread design and where you drive has everything to do with how tires wear.
Best case, closed shoulder tread and straight roads. Worst case open lug shoulders with large void ratio and hairpin turns.
This is a case of understanding what you're doing with your rig and how it's reacting.

just noticed you have Bilstein shocks , so do I . The earlier model 4600 had a problem with the lower mounting bushing on the fronts wearing out. They replaced mine free . Might be worth checking yours . It would affect the shocks performance . Have fun camping .

Thanks for the heads up. Same thing happened to mine years ago. Had them replaced, but don't remember taking the warranty route. [emoticon]

Have the same size tires as yours with a ~ 3,200 lb. TC unit and a diesel motor. I run 65 psi on the front and 80 at back when loaded. No unusual tire weat and I rotate them annually.
