Our test session was a trip to the Inyo Mountains and Death Valley. Even casual study of area maps clearly shows these two places aren’t close to conventional destinations or population centers; getting there required a lot of highway miles. Once in the dirt, we encountered a mixture of hardpacked soil, loose gravel, and blocky rocks ranging from golfball-sized to softball-sized. The highway drive was pleasant as the Mud Country tires rode smoothly and were only slightly more audible than the milder tires we’d been using. On the trail, lateral grip was reliable during cornering, and the tires conquered several steep climbs sans drama. The knobs have begun to chamfer at the edges; you can tell they’ve got a few miles under their steel belts. With the tread compound and the tread depth, there are many more miles ahead. Our Dick Cepek DC-1 wheels have been fortified with OMF Performance’s reinforcing rings.
