Race Distance: 164.905 miles/265.388 km (59 laps on the 2.795-mile/4.498-km temporary street circuit).

Potenza Race Tires Supplied: Bridgestone delivered 668 dry-condition ("slicks") and 288 wet-condition ("rains") Potenza race tires for use this weekend. All were produced at the Bridgestone Technical Center in Akron, Ohio. Per Champ Car World Series regulations, Bridgestone brought two dry-tire specifications and a single wet-tire spec, broken down in the following manner:

Standard dry-condition tires: Each car receives six sets of standard specification slicks (24 tires) for the weekend, to use in the practice, qualifying and race sessions. New for 2006, the primary Potenza selected for Surfers falls into the mid-range of the current Bridgestone street-course tire family. This spec was available to Champ Car teams that participated in the open test at Fontana earlier this year and was also used at all street-course type team testing at venues including Sebring and Firebird.

Alternate dry-condition tires: Each car receives two sets of alternate slicks (eight tires) to use this weekend; they are easily identified by their bright red sidewalls. At least one set of alternates must be used for a stint in Sunday's race. The Bridgestone alternate tire's construction is identical to the standard slick, but the alternate possesses a tread compound with better grip ("softer"), making it faster but possibly not quite as durable. The alternate Potenza for this weekend was previously used this season as the primary tire on the streets of Houston, Toronto, San Jose and Denver.

Wet-condition tires ("rains"): Each car receives up to four new sets of grooved-tread Potenza rain tires (16 tires) per weekend on road and street courses, as needed. In addition, each car may use two sets of same-spec rain tires issued at a previous event. Bridgestone officials opted for their "softer," or higher-grip, rain-tire specification for this weekend.

Quote from Al Speyer, Executive Director, Bridgestone Motorsport: "Like everyone in the Champ Car World Series, we at Bridgestone are thrilled once again to make our annual trek to Australia for one of the greatest events in all of motorsports. The Bridgestone red alternate tires will be used this weekend for the first time on the tight and fast street circuit at Surfers, and we are looking forward to enhancing what is always an exciting show. The Australian fans are among the best in the world when it comes to their enthusiasm and support, and I know they will appreciate the added drama that the alternate tires create."
