Five rib asymmetric tread pattern merges cornering with straight line stability. Long lateral grooves evacuate water from the center of the footprint. Four straight, wide grooves further heighten drainage for improved wet performance. Siped tie-bars reinforce block rigidity for control...

Five-rib directional pattern is optimally arranged for quick and direct steering response. Four wide grooves evacuate water from the center footprint to enhance wet performance. Multiple directional grooves and sipes give more edges to optimize grip on wet and snow-covered roads. A...

Super computer designed tread pattern optimize performance in differing weather and road conditions and ensure superb treadwear, noise, and ride comfort levels. Two in one shoulder blocks with jointless nylon edge bands provide excellent cornering traction,durability, and...

Twin reversible sidewall designs smooth sidewall for clean shiny appearances, serration style sidewall for more decorative look. Two-in-one shoulder block design provides for superb lateral grip, reduced irregular wear, maximum wet grip and stability. Four wide deep circumferential grooves...

Flat contact technology minimizes irregular wear by controlling the shape and pressure distribution of the tire footprint. Shoulder grooves work with the wide, flat tread radius to control irregular wear. Thousands of micro sipes protect the interior ribs from punch wear. Long wearing...

Beefy 20/32nd" tread depth applied to a wide, flat casing for 10% more rubber volume than our predecessor design, for much longer life in high scuff applications. Chevron block center ribs with lateral sipes effectively cut water film on wet roads for enhanced traction and safety. Thick...

New tread pattern concept couples sophisticated traction and smooth even wear. Solid shoulders with rigid interior tread bock configuration control heel/toe wear. Super-deep 30/32nd" tread pattern applied across a wide, flat radius for remarkably long miles to removal. Diamond cut block...
