Cooper Discoverer Rugged Trek vs Mickey Thompson Baja Boss A/T

The Baja Boss A/T is the more aggressive all-terrain and the better pick for buyers who spend real time on gravel, mud and sand. The Discoverer Rugged Trek is the more balanced choice, with a higher UTQG treadwear rating of 600 and a load index of 116 on a smaller 18-inch wheel. Both are XL-rated, T-speed all-terrains of nearly identical overall diameter, so the choice comes down to wheel size and how hard you go off-road.

• Choose the Discoverer Rugged Trek if you run 18-inch wheels and want a long-wearing all-terrain with a 600 UTQG treadwear rating for mostly road use with occasional dirt.
• Choose the Baja Boss A/T if you have 20-inch wheels and want maximum grip on loose surfaces, with interlocking tread blocks and self-cleaning sipes.
