Dunlop Quadmax Sport: Appearing Soon on Podiums Everywhere

Buffalo, NY—Dunlop ATV Tires is pleased to announce the release of the all-new Dunlop Quadmax Sport ATV tire, a next-generation design that is destined to carry competitors to the top of podiums across America.

“The Dunlop Quadmax Sport is a high-performance radial ATV tire that we’ve purpose-built for the track,” said Steve Yanacek, Dunlop’s off road and ATV product and marketing manager. “The new design takes our first generation tire and elevates its performance in every parameter, including turn-in, cornering, and drive-out traction. It all adds up to quicker times, lap after lap, in racing conditions.”

With more radial ATV tire experience than any other manufacturer, Dunlop’s engineers tapped into their wealth of R&D and practical experience to redevelop the first-gen Quadmax Sport. “We examined every aspect, including carcass construction, rubber compounds and tread pattern, to maximize racing performance,” Dunlop Tire Development Engineer Geoff Klein explained. “The new tire represents our best thinking, backed up by extensive real-world testing.”

For example, while it’s a lot of fun for recreational riders to slide the rear end around, Dunlop understands that racers need a tire to be predictable with progressive slide control and side grip for quick hook up and drive out of a corner. Utilizing the latest compounding technology, combined with a computer-designed, closely blocked tread pattern and tempered with Dunlop’s vast off road experience, the new Quadmax Sport offers greatly improved traction—both off the line for holeshots, plus ‘hook and go’ drive out of corners.

As a plus, the rear tires are duo-directional. When matched on the wheels, they perform extremely well rotating in the opposite direction. This added adaptability allows racers to reverse the direction of rotation as the rear tires wear and continue racing, a significant savings to teams.

“We worked just as hard on the front tire design and it tracks extremely well,” added Klein. “Going into corners it doesn’t push to the outside and the tire holds a line well with very good steering feel, allowing rider to change lines as desired.”

Of course, the Quadmax Sport maintains all the inherent benefits of radial construction, notably a superior contact patch and a compliant ride for less rider fatigue. Dunlop’s engineers focused a great deal of effort tuning the tire’s carcass plies and circumferential belts to preserve these desirable qualities even at the very edge of the performance envelope. Another benefit of radial design is found in both front and rear tires working together as a system, a key aspect of development that was perfected in real-world racing conditions at Dunlop’s Proving Grounds in Huntsville, Alabama and at race track across the country.

The new Quadmax Sport is produced in the following sizes and will be available at Dunlop retailers in the first quarter of 2008:
