Mickey Thompson | Baja Boss XS | 40X13.50R17LT | DOT-certified extreme-terrain tire | Load Range B | Sold individually
The Baja Boss XS brings competition-developed durability to an extreme-terrain tire that Mickey Thompson certifies for highway use. Its functional asymmetric tread, extreme SideBiters and silica-reinforced compound address demanding rocks and loose surfaces, while four-ply PowerPly PRO sidewall construction adds puncture resistance. For 40X13.50R17LT, the listed overall diameter is 39.8 in. and the tread width is 11.0 in.; these measured figures help compare fender clearance and the actual working tread. It is approved for 8.5–11.5 in. wheel widths and a 11.0 in. measuring rim. The 13.6 in. section width describes the casing at its widest point, which is different from tread width.
