I have a set of 265-70-17 Toyo AT II's on my Dodge 3500. I carry a camper most of the time. They have only about 25000 KM (Canada) and appear to be about half worn out. At this rate, they will be worn out by 50000 KM, (31000 Miles) Not happy with them at all nor the warranty. They carry an 80000 km warranty, but now I am told that the pro-rated price on a new set under warranty is based on suggested retail, and since they were discounted quite a bit, a replacement set would cost almost the original price anyway. Would not buy these again.
