Tires/max wear

Just My Opinion Ron but those new ones won't last either with that pressure. Your center belts are taking a beating from over inflation. Pretty sure I know tires, ask Chris where he bought his Duravis R250's tires from for his RV. :W
And you didn't mention male baldness pattern :B so I assume I struck a nerve :E

Well we will have to just disagree here.

HA, no nerve struck! Full head of hair here. I was tired from working on one of my Son's Dental Clinics he is building and was just concentrating on the tire issue.

Ok you say the new ones "won't last either". Not sure what you mean. Comparing the new tires to the ones with 40K I would say I was getting great mileage out of the MS2's especially with the heavy RV I tow and being a Dually.

You say they are overinflated. My door sticker says 80psi on the fronts. I am not a lot under the front axle rating with or without a load.

My 98 2500 4X4 RAM/Cummins I easily got 120K out of Michelins running 72 front and 45 rear solo. My front axle on the 15 Dually weighs a lot more then the 98 did.

If you l;look at most peoples pickups the front tires are very worn on the outside edge and the centers are worn on the rears. If you rotate front to back then the tires will equalize but will result in low mileage out of a set of tires.

I base my tire inflation on well over a million miles on my vehicles. I always get more than the average bear with my tires.

I would love to run less air in the fronts to improve the ride but I want the best tire life.

Just looked up my tire inflation chart. 65psi (15# lower as you said) gives 2,680# single application. My front axle weighs 5,440# that's 2,720 per tire. with 150# pin weight off that puts me exactly at tire rating. That would be fine if I rotated the tires. But I don't and I also account for braking and turning with my inflations.
