I ran dura's on both my 01 duallys . Weighed in about 18k lbs daily gcvw. Got about 35k out of them. Not bad for the price. But they don't come close to the wear of the Michelin LTX. Averaged 50-55k on 2 different sets of them. They just cost alot more. I have heard excellent reports on the toyo m55(?) although I'm about certain they don't come in the size you are wanting
