OSKALOOSA, Iowa -- Officials from the United States Racing Association (USRA) and American Racer Racing Tires announced on Saturday that they will allow drivers to utilize the Hoosier G60 tire for the upcoming Musco Lighting Great American Stock Car Challenge at the Southern Iowa Speedway.

"We've had several calls each day from drivers who have been forced to invest in the new Hoosier tire in order to race at their local track, but they want to attend this week's Musco Lighting Great American Stock Car Challenge," said event promoter Todd Staley. "As the only sanctioning body that is truly committed to the bottom line of both the racer and the promoter, we feel it's in the best interest of the drivers to give them a chance to compete against the best that this division has to offer without shelling out several hundred dollars for tires."

Racers across America are benefiting from the unmatched performance that the American Racer Racing Tires offer, and representatives from American Racer are confident that "this will let the market decide. Let the best tire win, but let them all run."

The prestigious event, which attracts America's most talented Stock Car and Hobby Stock drivers in the business, will feature a whopping $5,000 to win the USRA Stock Car finale on Wednesday at the Southern Iowa Speedway. While the top prize is huge, just making the 24-car main event field is worth more than the reward for winning most other Stock Car special events as all main event starters will earn a minimum of $1,000. For the companion USRA Hobby Stock class, a $1,000 paycheck awaits the winner of Wednesday's finale while all starters in the big dance will pocket at least $400.

Presented by Mike’s Tire & Alignment and Arnold Motor Supply, the 3rd Annual Musco Lighting Great American Stock Car Challenge will kick off on Monday, June 12, with a full program of qualifying heats and preliminary features in both the USRA Stock Car and USRA Hobby Stock classes. All cars will draw on Monday and Tuesday night and redraw for the feature that night. The top six cars from Monday will run a dash on Tuesday night to decide the first six inside row starting spots in Wednesday's finale. On Tuesday, the same procedures are in place with the top six to the outside row in a dash to be run on Wednesday.

Wednesday night's program will feature last chance races, with line-ups determined by points accumulated during the first two nights. Tow money will be paid to all drivers racing all three days that fail to qualify for the main events. Tow will be $100 for Stock Cars and $75 for Hobby Stocks. There will also be a $100 award for the longest tow.

During all three nights, national points in both classes will be awarded for the USRA Casey's General Stores Weekly Racing Series. However, a USRA license is not required to compete in this annual blockbuster. Drives competing on Hoosier tires will not be awarded points.

Each day, gates open 5 p.m. with hot laps at 7:15 and racing at 7:30. On Monday and Tuesday, admission is $12 for adults while Wednesday's tickets are $15. Juniors (13-18) and Seniors (62+) are $8 on Monday and Tuesday, $12 on Wednesday. Children 12 and under get in for FREE all three nights. Pit passes are $25 each night. There are no reserved seats for this event. All grandstand seats are general admission on a first-come, first-served basis.
