The 5-rib asymmetric tread design of the Sumitomo HTR Z III combines quadruple circumferential grooves with long lateral grooves to provide outstanding wet traction in addition to cornering and straight line stability.
Siped tie-bars reinforce tread block rigidity for better control and enhanced wet traction.
"3-D wave wall" increases water dispersion capabilities and reinforces center rib stability.
High carcass rigidity is achieved through the use of wide steel belts and high-tension casing plies.
The Sumitomo HTR Z III is available in 17 through 22 inch rim sizes and 55 through 25 series aspect ratios.
