You need to look at the tread depth... if you have 20" tires and buy "P-metric" (which is what most half tons come with), the starting tread depth is terrible (like 12/32"). I finally bought Falken Wild Peak AT3 in "LT" rated. Same size, but the starting tread depth is 18/32". They ride a bit more rough, but I can tell you they're the best wearing tire I've had. They hold great in the snow pulling a trailer. No hydroplaning.
Goodyear, General, Michelin LTX M/S, Michelin LTX AT2, Hankook Dynapro, Cooper, etc. were ALL JUNK! Never got more than 25,000 out of any of them. Granted, all were P-rated tires... You can't have the best of both... it's all about compromise.
Good luck - but I'd start by looking at tread depths and wear ratings.
