About the Bar Tread Pattern
The Bar (Multi-Bar) pattern maximizes ground contact area, giving a stable, even footprint on flat terrain. The continuous bar design distributes weight across a larger surface than lug patterns, which improves stability during lifting and loading on firm, level ground. A good fit for warehouse yards, paved lots, and flat jobsites.
