Toyo Tire (U.S.A.) Corp. engineers have developed new non-D.O.T. competition versions of the company's Open Country M/T tire.
Stan Chen, Toyo manager of events and motorsports, said the new tire version is essential because track conditions vary from muddy and slick to polished dry like asphalt, and trucks exceeding 800-horsepower need optimized compounds for best performance.
``This form of ongoing tire development also benefits consumers, as continuous feedback in punishing environments leads to data which helps to further advance product technology,'' Mr. Chen said.
The tire, now in its second year of competition, has new racing compounds that give pro teams the edge they require to continue winning races, Toyo said. The new compounds are not used exclusively, the Cypress-based tire maker said, because track conditions may favor the use of the traditional D.O.T.-legal Open Country M/T tires.
During its first year, the off-the-shelf Open Country M/T tires had success in off-road racing and rock crawling, won championships and scored podiums.
