Hi Forum. Noticed that my Michelin LTX M/S2 265/70R17E tires on stock wheel of my '04 Cummins were wearing unevenly ( I've not been good about rotating ) so I went for an alignment and rotation today. I like these tires from a performance standpoint, wet weather performance seems good to me, don't yet know about longevity. The gold standard for me are the original Michelin ( don't remember model but they were 245s ) that lasted almost 70k. The Toyo Open Country A/T that came next lasted about 40k. Anyways, I've been playing with pressures and lately I've settled on 50psi front and 35psi rear unloaded. Seems to make a big difference from the sticker 65psi front and 80psi rear. What pressures are others with 2500 owners running ? Below is a link to another tire pressure post that is relevant:

45/40

 

50/40

 

I run 52 in the front, and 45 unloaded in the rear.

 

I run around 55psi front and rear with 35" tires loaded as well as unloaded

 

There might be another sticker on the door or door jamb, listing light load pressures. Mine says 50/40.

I use the same tire, in a slightly different size. I use 50/45, since I carry a fiberglass cap and some other stuff in the bed. Based on tire tread temperatures, that's just about perfect.
