I have a 2002 Ram 1500 van conversion high top. I put 255/70/15 on it.

I had a set of General Grabber HTS 60 on it that were decent. Lasted for about 40k. As you know these vans eat tires.

Now have a set of Yokohama Geolanders on it that I like a little better, but they were a little more expensive.
