I have been looking at the Grabber All-Terrain tire for some time now and i am new to tires. If someone could tell me their point of view it would help out alot. Here is a link if you havent seen them.

I have a Grabber AT spare 31X10.5. I've never used it (knock on wood), but it loooks like it would perform nicely offroad. The 31X10.5 runs a little short but they are WIDE on stock 15X7 rims. 30.5" X 10.4"..
So you wont gain the height (ground clearance) that you would from a BFG AT KO, but these are wider, so traction might be better. Why not go for the Grabber M/T? I hope this helped a little.

That tire is also sold as the Brigadier Sidewinder AT. The tread is similar to the BFG AT. Don't know much else about it, but it's a great way to save $40 to pick up a spare when you run 4 BFG ATs on the road.
