2024 OFF-ROAD TIRE GUIDE The Latest Off-Road Tires For Race Or Weekend Fun By Mike Vieira The best off-road tires come from those manufacturers who use Baja as their testing grounds. Improvements in traction, load capabilities, puncture resistance and more, all come from experience in the most extreme conditions. The developments found in SCORE Baja racing trickle down to the dual-purpose tires for truck and UTV enthusiasts. Last issue, we spoke with several tire manufacturers who gave us insight into some of these developments and what they mean to the racer and SCORE fans alike. For this issue, we gathered the latest tires available from various manufacturers, showcasing both their racing and off-road rubber that has come from years of Baja racing history and development.
