When I bought the Jeep and saw the Duelers, I asked the dealer if they would swap them for the Goodyear Wranglers, on another vehicle. They wouldn't, and I was extremely skeptical, of the tires. This was due to my experience with the Dueler D684s that came on my wifes 04 Suzuki XL-7. They were terrible, and wore out at 15K.
These however have been outstanding. I'm replacing a 65K tire at 65K. I didn't think it was possible to get the actual mileage they were rated for, from ANY tire. I'm putting new Dueler A/T RH-S on this week.
