BRIDGESTONE POTENZA FAST FACTS

Bridgestone Presents The Champ Car World Series Powered by Ford Champ Car Hurricane Relief 400 - Las Vegas Motor Speedway September 23-24, 2005 - Round 11 of 14

Race Distance: 249 miles/400.727 kilometers (166 laps around the 1.5-mile/2.414-kilometer oval).

Potenza Race Tires Supplied: Bridgestone delivered 744 dry-condition Potenza race tires for use this weekend. All were produced at the Bridgestone Technical Center in Akron, Ohio. Each entry receives nine sets (36 total tires) to use as its team sees fit in the practice, qualifying and race sessions. In addition, rookie drivers receive an additional set to use during the rookies-only practice session Friday afternoon. The "slicks" - tires with a smooth tread surface - for this weekend are a completely new compound-construction formula, given the Bridgestone seal of approval following a successful private test at LVMS in early August.

A Stagger-ing Effect: For oval-track events, Bridgestone molds the diameter of its right-rear tires slightly greater than that of the left-rear tires. This effect, called "stagger," helps Champ Cars turn more smoothly and naturally on ovals, much the way a Styrofoam coffee cup will roll in a tight circle when placed on its side (with the smaller base end of the cup remaining on the inside of the circle). The size differential in the Potenza oval tires is minimal - the right rear's diameter is 0.35 of an inch more than the left rear - but the effect is very similar to that of the rolling cup and just as effective.

Quote from Al Speyer, Executive Director, Bridgestone Motorsport: "We're excited to return to Las Vegas for the unique doubleheader featuring the Champ Cars and trucks that's certainly a race fan's ideal evening. Bridgestone is showing its commitment to this event in a couple ways. First, even though the Potenza tires performed quite well in last year's Las Vegas race, our race tire development group has designed, tested and produced a completely new tire specification for this weekend that we believe will yield the same exceptional durability throughout the stint and exceptionally consistent performance from set to set. Second, Bridgestone applauds Champ Car's effort to hurricane victims with this weekend's race and on-line charity auction with our friends at CARA Charities. Bridgestone's global group has already donated more than a million dollars to the relief effort and we'll add to the tally by directing a portion of the Bridgestone Pole Award charitable contribution that way in Las Vegas."

Bridgestone Pole Award: Bridgestone Motorsport awards $5,000 at each race to the driver who wins the pole. Additionally, Bridgestone donates $2,500 to the Hole in the Wall Camps (Official Charity of Champ Car) and $2,500 to a local charity in each race market, with the latter donation this weekend earmarked for the hurricane relief effort. Besides the monetary prizes, the Bridgestone Pole Award winner receives a one-of-a-kind trophy handmade by a camper at Camp Boggy Creek, a Hole in the Wall Camp. Through 10 races in 2005, Sebastien Bourdais is the leader with four poles, followed by Paul Tracy with three. The driver with the most poles at season's end earns a $30,000 bonus, with another $10,000 going to his chief mechanic.
