The new XT400 tire from System 3 combines the radial carcass of the XTR370 tire with the mud-ready tread of the XM line to create an innovative 10-inch wide smooth-running mud-trail hybrid.

It has aggressive shoulder lugs to pull through deep ruts and deep rim guard that protect the wheel lips in addition to reduce the chance of a pinch flat.

Here is more from System 3’s press release:

Yorba Linda, CA (March 23, 2021) – By combining two high-performance tire designs, System 3 Off-Road has created the new XT400, a mud-trail hybrid tire that delivers extreme trail traction. The XT400 combines the radial carcass of the rugged XTR370 tire with the mud-ready tread design of the XM tire line.

The new XT400 tire features a 10-ply rated radial carcass and 10-inch wide footprint, with multi-stage lugs up to 2.0 inches deep. The tire’s aggressive shoulder setup gives drivers powerful traction and control through deep ruts and loose terrain. And a deep rim guard protects wheel lips and helps avoid pinch flats.
