Bridgestone Presents The Champ Car World Series Powered by Ford G.I. Joe's Presents the Champ Car Grand Prix of Portland, Portland Intl. Raceway
June 17-19, 2005 -- Round 4 of 14

Race Distance: 206.22 miles/331.88 kilometers (105 laps on the 1.964-mile permanent road course).

* Potenza Race Tires Supplied: Bridgestone delivered 668 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 contains the "softest" standard road-course compound and construction that Bridgestone employs in the series. The same spec of tire was used earlier this season at Monterrey, Mexico.

* 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 sidewalls. At least one complete 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, a more durable spec for the faster road circuits and a "softer" spec for slower circuits. The softer "street-course" rain tire is available this weekend.

Quote from Al Speyer, Executive Director, Bridgestone Motorsport:

"We're ready to tackle the Champ Car schedule in earnest now, with seven road and street events in the next 11 weeks. First up is Portland, and Bridgestone is very excited to be there in 2005 as the Official Tire of the track. We'll take great pride in watching the Champ Cars racing under the new Bridgestone bridge on the front straight. We enjoy Portland because it's a demanding track that often necessitates use of both the Bridgestone dry and wet tires in varying conditions. We're also returning to Portland with the alternate tires that add an exciting element of strategy as teams decide when to use their Potenza 'reds.' We're looking forward to another unpredictable and exciting weekend of racing at PIR."
