The staggered and stepped tread blocks, the zigzag groove pattern and the open shoulder design work together to improve the soft, loose and uneven terrain gripping capability. The tire increases the grip on the terrain surface, boosting the off-road performing capability. These tread elements also maintain a clean footprint. They clean out mud and snow and eject rocks from between the tread elements. This keeps the footprint clean and prevents mud and snow from blocking the tire from its contact with the road surface. It also actively prevents stone retention from harming the casing by drilling rocks into the tread.
