All terrain tires for half ton towing

Recommended Posts

I recently bought a '20 Silverado 1500 with the duramax engine. I want to upgrade the tires and I'm looking for some help deciding between the top competitors. I'm not planning on lifts or many suspension mods outside airbags for the back so I would like to stick to the stock wheel size of 275/60/20 (33x10.5"). My truck came with 18" wheels so I'll be replacing wheels likely with 20x9 KMC KM722 technic which have a load rating of 2500# each. This  will require a reflash of the system to adjust for added tire size but that should be possible with my dealer.


All this is to say I don't need to go with a monster load rating. Something around 115/D rated tires should be fine for my half ton. I would like an all terrain tire for the traction. I will tow in snow going camping at the local ski areas and when I'm not towing I would like enough traction for fire roads and driving on the beach. Wet traction is really important since I'm in the Seattle area and drive in rain allot. My last rig I ran highway tires and a separate set of winter tires but I never took it up trails or on the beach with those highway tires and I would like the added capability with this truck. In the future I may still run a dedicated winter tire. Fuel mileage is always of some concern, I can't find much data on the full impact of AT tires vs highway tires outside of a general 3% loss in mpg. I'm very interested in any feedback related to mpg differences. 



My top tires are below. I'm looking for feedback on these or others that have good wet traction, snow/ice traction, good mpg (relatively) and least concerning decent dry road handling and noise. Any of the tires listed should have plenty of traction for my level of off road use.
