4wheel parts is terrible. I would NOT buy from them. X-terrains are a decent tire. MTRs are much better and for the price of X-terrains they are not worth it at all. I'm replacing my X-terrains with either MTRs or Creepy Crawlers soon. For a rig that sees alot more highway miles than offroad, then that would be the only reason I'd want to go with the Xterrains. They have a much harder rubber compound than MTRs or BFG Muds.

Discount tire is tough to beat IMO. They can get you any tire you want from BFG, Interco, Maxxis, Pro-Comp..you name it they can get it and always good prices and you'll have a local place to mount, re-mount, balance...fix holes...etc. Tough to beat.
