Hi Chuck, I don't know what the best tire is but I can tell you what has worked best for my Trucks. My 2012 Chevy 3500HD DRW's came with Michelin's, I have also run Toyo's because the Toyo's were much cheaper than the Michelins. I ran the Toyo's on my Frieghtliner and they gave excellent service. I also ran a set of Toyo's on my 2008 Chevy Silverado 1500. I really like the Michelins but they have gotten so expensive so I tried the Toyo's, I will go with Toyo's on the 3500HD when I replace them. I also will put a set of Toyo's on my 5th wheel next spring. I try to replace the 5th wheel tires ever 3 years. I have Goodyears G114's on the 5er now and they are wearing great. But again they are very expensive? Good Luck with your choice... Happy Trails......
