DieselFan, the MICHELIN LTX A/S in oem 265/70-17 is a 121-factor Load Range E, LRR tire. The stock wheels can carry no more, and the RAWR is less than the combined tire weight capacity. The M/S may be LRR rated, but the highway rib A/S is superior from the standpoint of FE (where the M/S is likely better on wet pavement and non-solid surfaces).

I got 120k miles with 4/32's remaining on the original set, and will come close to 250k miles when the first replacement set is ready to be replaced. Expensive up front, but cheap considering the lifespan. My experience is not unique, nor are all miles on highway.
