Michelin LTX M/S Load Range E -
Have had two sets on my 2500 and they lasted about 90k miles each. Towing about 1/4 of the time. Last set was dry rotting when replaced. Cost was about $0. 01/mile.
Had three sets on my 3500 and they lasted about 155k miles each. Towing 1/2 of the time. Lot of highway miles. Cost was about $0. 01/mile (dually).
Nexen Roadian HT Load Range E-
Currently have these cheap S Korean tires on my 2500. Needed some cheap tires at the time and let tire dealer talk me into these. He told me they were made in USA, but later noticed that they were not. They have been surprisingly pretty good as far as traction. Ride is not as good as with the Michelins, but is okay. I don't expect to get high miles out of these tires, but they should last about 30k miles based on wear so far. Cost was about $500. Will have to see how the cost/mile turns out when they get worn out.
I have the procomp at , love them. I got 46,000 and still more room. the fronts wore a little funny, but it was my fault, I didn't catch the wheel bearings fast enough. now i have to do all the steering linkage, before I buy a new set. the only thing i didn't like, and it may be normal is that the inside side walls show a little bit of checking. I don't drive the truck much. mostly weekends and vacations, and maybe not every weekend.
the procomps are good in the snow, rain, on the beach and the road. blows away the BFG's I used to run on a Bronco.
Next set is going to be a set of goodyear Duratrac, though. ONLY because of the weight rating.
