I am sold on the Michelin LTX (not sure if it superseded now) had them on (3) different Cummins 5.9 all 4x4's 03 Std Cab 2500, 06 Quad 2500 and 06 Quad Dually 3500 - 150,000 miles in 5 years - great in the wet, good in the snow and light ice, terrible in mud - all loaded towing from 8,000 to 14,000 lb trailers in the Pacific Northwest hauling horses. Super quiet, smooth, durable, long lasting, good MPG. Hands down the best tires I ever owned for all around variable towing and long hauls year around never had an issue with any.
Also have run Cooper Discoverer's on 1978 F250 4x4 gasser. Good tires, excellent traction wet or snow, faster wearing, noisier, way less money than the LTX but a good tire.
