Mickey Thompson | Baja Boss M/T | 42X13.50R20LT | mud-terrain truck tire | Load Range D | Sold individually
The Baja Boss M/T is a serious mud-terrain tire for trucks that see rocks, ruts and loose ground. An asymmetric tread, aggressive Sidebiters and PowerPly XD sidewall construction focus on trail traction and durability while retaining road-use capability. For 42X13.50R20LT, the listed overall diameter is 41.8 in. and the tread width is 11.3 in.; these measured figures help compare fender clearance and the actual working tread. It is approved for 9.0–11.5 in. wheel widths and a 11.0 in. measuring rim. The 13.8 in. section width describes the casing at its widest point, which is different from tread width.
