The KO2 has slightly better braking and traction than the Wrangler UltraTerrain AT on gravel, even on sand, but the K02 is more susceptible to freezing up in winter. So, UltraTerrain is the better choice for wet or snow tires, and KO2 is the winner between Goodyear Wrangler UltraTerrain AT and BFG KO2 for off-road performance.
