Dunlop has brought a new, more durable compound choice for its rear D211GP-A N-Tec AMA Pro control tire to the Buckeye Superbike Weekend at Mid-Ohio Sports Car Course less than three weeks after AMA Pro riders first tested the new tire. “We started with four different more durable compounds than we had last year,” Dunlop Tire Development Engineer Tom Grolemund told Roadracingworld.com. “We’ve used them at club races to weed them out to what we felt was the best. We brought that [best candidate] to NOLA [Motorsports Park], and then as soon as we saw the positive results it was literally a phone call from NOLA to the plant and go from there.” Thanks to its N-Tec manufacturing technology, Dunlop was able to produce 300 of the new 8477 compound tires and deliver them to Mid-Ohio just 17 days after the June 26-27 test at NOLA Motorsports Park. The new compound will only be available to riders in the Daytona SportBike class at Mid-Ohio.
