When to use each

All-terrain tires should be used when you frequently travel rough, rocky, or muddy roads. They feature reinforced carcasses and rugged construction for tackling these terrains while resisting cuts, chips, and snags. Unlike mud-terrain tires, all-terrain tires offer better on-road performance and reduced noise levels for a quiet and comfortable ride quality.
