Introduction:· The design of transverse strong pattern blocks and the mutual connection of middle stiffeners make the tire have better toughness, effectively improve the overall stability and comfort of tires. · Vertical and horizontal groove design can effectively prevent creep and lateral extrusion caused by lateral force of block, effectively improve wear resistance, and effectively reduce internal friction and uneven wear. · The innovative design of heat dissipation hole depth of crown pattern block can minimize heat generation and effectively improve TKPH value.
