I used one on mine a couple years ago. I liked the ride & extra clearance but didn't get great mileage from it. Only about 8,000 miles. But then I haven't been getting exceptional mileage from any tires. My best mileage has been about 10,000 miles on the D250's. I'm running Bridgestones now and only got about 8,000 miles on the rear. 5,000 was on my trip this summer pulling the trailer on every crooked road I could find at Shady Valley and Deals Gap.
Running 41 psi front and rear.
