I have P275 / 65R18 Goodyear tires. Treadware 500, Traction A, and Temp B.....and they only have 35,000 miles on them. We took a long 2,500 mile trip last year and it took a huge toll on tread ware...
Just dropped on a set of Toyo Open Country A/T II's Toyo Open Country A/T II 50k mile warranty on LT's with a load capacity of 3400# ea. We'll see how well they last.
