Main groove with taper recess design on both groove sides and bevel design on lateral groove wall allow tread to fit more closely on rugged road surface during rolling to prevent uneven tread wear. Sipe design on center rib can homogenize rib stiffness and further enhance wet performance. Enlarged tread shoulder block width ratio to overall tread width can increase contact area of tread shoulder and strengthen durability of tread shoulder. Shallowized lateral groove and sipe design on tread shoulder strengthen pattern block stiffness and further enhance endurance performance of tread shoulder. Broadened tread width design enlarges contact area, strengthen sidewall endurance and enhance tread wear mileage.
