I have used nothing but Michelin LT tires on my TV's until this camping season. My Michelins that I have used are LT265/70R/17E M/S2 tires rated at 3195 @80 PSI. These run quite and have provided good service on my 2008 Ram through all type of weather conditions.
I am changing to LT285/70R/17-125R Nitto Dural Grapplers with Mickey Thompson Sidebiter II wheels. Since I am going to be towing a heavier 5th wheel this year a CC34RL; and want the extra support of a 10 PLY tire. These are rated for 3638 LBS at maximum air pressure which I will not be using but what the axle loads are per a certified weight scale.
2016 34RL CC; 2008 Ram Mega Cab 2500HD, 6.7L, 68RFE 6 speed, 4X4, Smarty S67
