Plan the whole build around this tire’s scale. The 42X13.50R20LT Baja Boss M/T has a published 41.8-inch diameter, load range D and a 128Q service description. It brings a premium mud-terrain pattern to a 20-inch wheel, with clearance, wheel capacity and vehicle requirements to verify before installation.
The Baja Boss M/T uses an asymmetric tread, large Sidebiters and stone-ejector ribs for rough-ground traction and debris release. PowerPly XD reinforces its sidewall construction, while the silica-reinforced compound supports wet-road performance.
