Goodyear changes Busch road course tires

The Busch Series will run on a slightly different tire this year on road courses than it did last year.

The tire will be a little more resistant to heat and wear than in the past, said Goodyear's Chad Fletcher, who oversees the Busch program for the tire company.

The Busch tire is different than the Nextel Cup tire because the Busch tire is smaller in radius in order to keep it the same radius as the old rain tire compound, which will be used if it rains Sunday. Goodyear slightly enlarged the radius of the tire in 2005.

"In order to match the rain tire up to this tire [in radius], we went back and made some construction updates to accommodate the faster speeds we're seeing on the cars," Fletcher said. Scenedaily.com
