Hey bud. I'd say they're about as good as the Baja Claws I had. They absolutely sucked in the mud. They wouldn't clean, no matter how much I spun them. I say they're probably not good because the tread pattern is very similar. Now in the sand, you couldn't shake a stick at them. I pulled a 1-ton dually loaded with the utility bed, full of tools, a bed crane, and a 50 gallon accessory tank full of fuel out of a sand hole with mine. Sure, the tires spun down to the depth of the sidebiters. When it got there, it hooked up and drug the truck up the hill and out of the ruts. Price-wise, the 35x12.50 Baja Claw Radials like I had, run $169 per tire from National Tire & Wheel. The X-terrains from 4WPW run $177 for the same size. I've just been giving you a spiel on my Baja Claws. I have no idea how the X-terrains are.
