I have had a lot of different popular tires on my Dodge Ram 2500 while pulling my TT but the Bridgestone Duravis m700 are by far the best tire I have ever put on my truck. They are a commercial grade tire that have great traction for a mild AT tire. They come factory on GM products. There are claims of over 50-60k towing heavy loads on the web. I have never got more than 20-25k out of any tire with regular rotations every 3k and rebalance every 6k. I have 5k on them now and I have no measurable wear. They are awesome in the snow. No more need to put in 4wd every snow storm here in Colorado. I really like these tires. Good luck.
