I ran a set on my 2500 for about 20k miles. Two of them started seperating so I finally got 4 new tires. I wouldn't run recaps again! They didn't ride as good as new, we very far off balance, didn't last. The tire shop who convinced me to cap my tires sells a lot of caps to guys running in the forest and off road. They work really good for them on gravel roads and not running high speed. I did all the bad things to my caps, drove down the freeway at 83 mph for mile after mile, loaded or empty. Good luck, Paul
