DOVER, Del. -- Some Chase drivers at Dover International Speedway this weekend are voicing concerns about Kyle Busch's participation in the recent Goodyear tire test in preparation for the Pep Boys Auto 500 at Atlanta Motor Speedway in October.

Crying unfair advantage, Greg Biffle said the fact that Busch was the only Chase driver to participate in Tuesday's test is a "significant deal."

“

No doubt that will help [Busch] because they had test data on the car and were able to gather some information for going back.

"I've got a really bad memory, and if my memory serves me correctly they said that they wouldn't use Chase cars to do tire testing once the Chase started," Biffle said. "It does give you somewhat of an advantage, certainly."

Busch, Travis Kvapil and Scott Riggs all participated in the one-day test to finalize the tire selection for the Oct. 26 Chase race.

Those teams were selected because they also participated in a tire test at Atlanta on July 21-22. Goodyear engineers felt that bringing back the same teams and drivers would maintain continuity and build upon the results of the first test. Using the results from that prior test, Goodyear returned with several potential race combinations to evaluate and chose the one that worked best.

The Goodyear Tire & Rubber Company tested in order to come up with a new right-side tire that will give the Cup cars more grip as opposed to conditions during the spring race where several drivers complained the tires were too hard.

Biffle fears it will give Busch a clear edge on the Chase field in October.

"No doubt that will help [Busch] because they had test data on the car and were able to gather some information for going back," he said.

Points leader Carl Edwards said ideally no one would test during the Chase.

"In a perfect world no one would get to test and we would go to the racetrack and we'd race. I think that's the best thing," Edwards said. "It definitely would seem inherently unfair to have certain people in the Chase test the Chase tracks and others not, but I don't think one test will make or break the deal." (Continued)
