37x12.50R17LT Pro Comp Mud terrain three-ply tires are mounted on 17x10 Raceline Monster beadlock wheels. The Mud Terrain three-ply tires were designed for military use and are excellent tires for us. Their strong nylon construction shrugs off abrasions and the compound is sticky on the rocks. We hope that Pro Comp continues to manufacture these tires. The Raceline Monster beadlocks are cast as beadlock wheels. The valve stem is in the spokes where it's easy to access. The 17x10 wheels are strong and true.
