I've never gotten good mileage out of oem tires. I would suggest it's not the name of the company but rather the grade of tires on the truck.
I agree with the same statement. My buddy with his new 3500 HD had the same issue on Michelin OEM tires. 30K miles and they are gone when carrying close to full weight.
What I have heard is, and it was confirmed by a Firestone rep trying to find new tires for a friend on a 2500 HD. The auto makers go to the tire companies and want their standard tires tweaked to the auto maker OEM tire requirements. Things like load capacity, nice ride, good brand, traction and then there is mileage. In order to get better ride to sell a new truck, they tweak the tire compounds to get better ride and this is offset by lower mileage wear when at the load rating. Something has to give, and mileage looses on an OEM tires. If you get the same tire in the aftermarket not OEM tweaked, then it can get to the mileage warranty the tire manufacture states at full load, but the tire may ride rougher.
I'm in the same boat on my F350, this spring I need new tires due to age. This will be my 4th set of tires on this truck. Something in the tire industry changed about 6 years ago where the truck is real squirmy when the tires are brand new. Many state this wears off in 500 miles, but in may case it took 3,500 miles then the truck handled the way it use to. There is no rating for tire squirm or side wall flex I know of. Choosing a good brand thinking it will work on your truck is a shot in the dark some times when towing.
Hope this helps
