The Pro Comp Xtreme Mud Terrain is more expensive than some other highly rated mud tires such as the top-ranked Goodyear Wrangler MT/R with Kevlar (*Est. $210) . It is designed for drivers whose hobby is serious off-roading. Despite its name, experts say the Xtreme Mud Terrain isn't spectacular in mud -- it clogs, spins and slips in two tests.
One reviewer notes that this Pro Comp tire should have been called the "Xtreme Rock Terrain," because it excels at crawling over boulders. However, some owners and experts report that sharp rocks have torn up their Pro Comps. On-road, testers say the Xtreme Mud Terrain is quieter and handles better than many other super-aggressive tires.
Several websites for off-road enthusiasts review the Pro Comp Xtreme Mud Terrain. Four Wheeler includes it in a 10-tire, mud-only shootout. Petersen's 4Wheel & Off-Road magazine, Off-Road.com and Project-JK.com all take the tire on-road and rock crawling, but the reviewer at Project-JK.com doesn't test the Xtreme Mud Terrain in mud. We found more than 80 owner-written reviews at Offroaders.com.
1. Petersen's 4 Wheel & Off Road
The Pro Comp Xtreme Mud Terrain isn't impressive in mud, Petersen's 4Wheel & Off-Road tester Jerrod Jones finds. It's not bad, though, and Jones adds that it's excellent on rocks and can still be driven daily on the highway.

2. Petersen's 4 Wheel & Off Road
In its smaller sizes, the Pro Comp Xtreme Mud Terrain finishes second in this comparison test of five normal-size mud tires for daily drivers. Testers find no fault with the Pro Comp, but the first-place Interco TrXus MT performs better in mud.

3. Four Wheeler
The Pro Comp Xtreme Mud Terrain has problems with off-camber ruts in this mud test, finishing next to last among 10 tires. Still, testers say it's fairly quiet and doesn't vibrate much on the highway. This review says the Xtreme Mud Terrain has a 40,000-mile tread--life warranty, but that's incorrect; the warranty applies to a different tire, the Pro Comp Xtreme All Terrain.

Off-Road.com tester Pete Bach says he is impressed with the Pro Comp Xtreme Mud Terrain's rock-crawling ability, although the tread loses a few chunks along the way. He finds only a little mud during his test, and he predicts that stickier mud would gum up the tires.

Edwin Oh, who runs this site for Jeep enthusiasts, reports on the set of Pro Comp Xtreme Mud Terrains he used on his own Jeep JK Wrangler at an organized off-road event in Moab, Utah. He says the tires are a little louder on the highway than his previous BFGoodrich mud terrains, but they get good traction on wet roads and stick well to slick rocks. He did puncture a sidewall on a sharp stick, but he says that would have happened to any tire.
