The System 3® XTR370 All-Terrain Radial SXS Tire is an extremely capable and versatile off-road performer with strong 8-Ply Radial construction!
The System 3 XTR370 X-Terrain UTV tire is a rugged, all-terrain radial tire built to conquer the toughest UTV, side-by-side (SxS), and off-road conditions that are out there — from rocky trails to dirt, gravel, and sand. With a durable 8-ply rated carcass and advanced sidewall construction, the XTR370 offers a blend of durability, strength, and ride comfort that you rarely find in a single tire.
Its aggressive, open tread block design features multi-angle shoulder blocks and deep tread depth (from 0.75" up to 1.25", depending on the size), giving this tire excellent bite, traction, and stability — even when you’re cornering hard or negotiating uneven terrain. Meanwhile, the super-deep rim guard protects your wheels and helps prevent pinch flats, a common concern when wheeling off-road.
Whether you’re hitting trails, climbing over rocks, ripping through sand, or simply upgrading your ride — the XTR370 gives you the confidence and control to go further and take on the most challenging terrain.
