System 3 XT400W Extreme Mud Radial UTV/SXS Tire

The System 3 XT400W is a purpose-built extreme mud radial engineered for UTV and SXS riders who refuse to get stuck. Its specialized wide design delivers a full 12-inch tread width that keeps your machine riding over deep ruts instead of dropping into them — maximizing the flotation you need to power through deep muck and soft, broken trails.

Aggressive two-stage lugs measure up to 2.5 inches deep to cut through thick mud with relentless traction, while the shoulder tread overhang and wide lug spacing work together to maximize bite and promote self-cleaning so the tire keeps churning without clogging. A 10-ply rated radial carcass balances flex, flotation, and toughness, giving you serious puncture resistance and a confident ride in the most demanding conditions.
