HAUBSTADT, Ind. – United States Auto Club and Midwest Sprint Car Series officials have suspended and fined driver Kendall Ruble and entrant Jerry Ruble for failing a tire test after the completion of the recent Haubstadt Hustler on Sept. 19 at Tri-State Speedway.

Ruble, who was initially credited with the victory, has been disqualified from the event.  Chase Stockon, who finished in the runner-up position that night, has been credited with the feature victory.

The test verified by laboratory findings revealed that Ruble’s tire had been altered and did not conform to the benchmark provided by Hoosier Tire Company.

Section 309.C of the USAC Rule Book states that any solvents or chemicals applied to the tire that alter the chemical makeup of the compound or have the effect of altering tire durometer or construction are prohibited. A tire can be confiscated at any time.

Ruble has forfeited points and purse winnings from the event, was fined $2,500 by USAC and he and Jerry Ruble have both been suspended for six races from both MSCS and USAC competition.

“It is important for USAC and for MSCS to give confidence to competitors that we will keep the competition fair,” USAC Executive Vice President Levi Jones said.

“Both MSCS and USAC will continue to work together to create a level playing field for all participants,” MSCS owner Tom Helfrich added.

Winnings and points will be adjusted accordingly to reflect the change in the final results of the Haubstadt Hustler.
