Race Distance: 175.518 mi./282.469 km (63 laps on the 2.786-mi./4.484-km permanent road course).

Potenza Race Tires Supplied: Bridgestone delivered 762 dry-condition ("slicks") and 304 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 slicks (24 tires) for the weekend, to use in practice, qualifying and race sessions. The standard dry-condition specification for this event contains the midrange standard road-course tire compound and construction that Bridgestone employs in the series. It is the same spec run last year at Mexico City and earlier this season at Cleveland.

* Alternate dry-condition tires: Each car receives two sets of alternate slicks (eight tires) to use this weekend. The alternate tires are easily identifiable by their red-colored sidewalls. At least one set (new or used) of alternates must be used for a stint in Sunday's race, but there is no mandate to when or how long the set must be run. The construction of the alternate tire is identical to the standard slick, but the alternate tire possesses a tread compound with moderately increased grip ("softer"). While the alternate tire contains additional speed potential, it trades away some of the long-lasting durability of the standard dry-condition tires.

* Wet-condition tires ("rains"): Each car receives up to four new sets of grooved-tread Potenza rain 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 has two rain-tire specifications at its disposal for the 2004 season. The more durable road-course rain tire is available this weekend.

Quote from Al Speyer, Executive Director, Bridgestone Motorsport: "For the fourth time this season, Bridgestone is utilizing the alternate tire concept to enhance the racing competition. This weekend, however, may see the greatest difference in lap times between the alternate and standard Potenza specs because the compound make-ups have more variation in hardness than in the previous uses. We believe the alternate tire adds an exciting new element of strategy and we'll be curious as to how and when the teams employ the 'red stripes,' as many are calling the alternate Potenzas, to their best advantage. It should help to make an electrifying conclusion to this exciting turnaround season for the Champ Car World Series."
