Dunlop Launches Sportmax D211 GP-A Tires

Tire manufacturer Dunlop recently unveiled its latest product, the Dunlop D211 GP-A tires, at the Auto Club Speedway AMA National in the US. Used exclusively in the Daytona SportBike and SuperSport classes, the D211 GP-A follows the Sportmax D211 GP made in the UK.

The Sportmax D211 GP-A complements Dunlop's family of Sportmax tires, shares both IRP and MT technology with the Sportmax Q2-a tire designed for street and track use, and borrows the MT technology with the sport/touring oriented Sportmax Roadsmart.

The new tires are based on Dunlop’s N-TEC technology, a special hybrid construction that optimizes the way the tires perform. For 2010, the Sportmax D211 GP-A employs a new stiffer nylon ply material that improves cornering, steering and linearity response in
transitions, rider feedback, and overall stability.

“The tread pattern for the D211 GP-A traces its origins to Dunlop's cosecant-curve design, developed with the assistance of FEA (finite element analysis). Carefully placed tread grooves continuously coincide with the forces running through the tread face of the tire during cornering. As the curving tread pattern travels across the tire to the shoulder area, the driving and braking forces remain consistent as cornering forces come into play,”
a company statement reads.

The new Sportmax tires have been tested by racers like Danny Eslick, Martin Cardenas, Steve Rapp, Josh Herrin, Tommy Aquino, Shawn Higbee, Jamie Hacking, the Wood brothers, as well as by current Dunlop test riders Rich Conicelli and Danny Roberts.
