I need new tires on my 3rd gen t4r. Looking at the Cooper AT3 in 235/85/16 E or 265/75/16 C. From what I understand, the C load rating matches the GVWR best, but I see a lot of guys running the 235 on the same weight rig. This is my DD, so a good amount of highway use. Also, being in the UP they'll see a lot of ice and snow. Any comments or suggestions? Thanks, Ian
