I recently retired, and my 2008 Everest is my first RV. In July my cousin and I drove to within about 100 miles of the Arctic Ocean, on the tire - eating Dempster Highway.
See photo of my new factory supplied Firestone tire with a puncture in the sidewall.
Interestingly, my Tireminder TM66 didn't respond to the rapid air loss until I was almost stopped. I was alerted by the sound of the tire flapping and wasn't going more than about 30 mph, so it wasn't a big deal. We did about 800 more miles of rough and sharp gravel road with no spare for the truck and no cell service. I had expected to be able to find a replacement tire for a spare in Eagle Plains, Yukon, so we continued on. There was no tire in the required size neither there nor in Inuvik. It was a relief to get back out without any further tire issues.
The Sailuns performed flawlessly, as they have since I put them on the Everest when I bought it in the spring. I have towed about 12,000 miles with them so far, and am very impressed. And they are much less expensive than tires that are far inferior.
