I've decided that I'm going to start buying this wheel and tire setup so I'll be ready when the OEM tires are toast. At 40,000 miles a year I think I'll get my monies worth out of them and they're suppose to also help the MPG on the highway which at $3.39 a gallon and two tanks a week would sure come in handy, not to mention they look tough and will fit a stock 3500 4x4. I'm going to call them Monday and see if I can't get some more info.
Here' a link to the Technical Info about this upgrade.
