BRIDGESTONE POTENZA FAST FACTS Bridgestone Presents The Champ Car World Series Powered by Ford Champ Car Grand Prix of Portland - Portland Intl. Raceway, Portland, Ore. June 16-18, 2006 - Round 5 of 15
Race Distance: 206.22 miles/331.879 km (105 laps on the 1.964-mile/3.161-km permanent road course).
Potenza Race Tires Supplied: Bridgestone delivered 690 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 specification slicks (24 tires) for the weekend, to use in the practice, qualifying and race sessions. The standard slick for Portland is a newly developed tire for 2006, but has already seen significant track time. It was used at the Portland open test in April and was the standard-spec Potenza for the race weekend last month at Monterrey. This is the highest-grip standard road-course compound in the current Bridgestone arsenal.
Alternate dry-condition tires: Each car receives two sets of alternate slicks (eight tires) to use this weekend. The alternate tires are easily identified by their bright red 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 Bridgestone alternate tire is identical to the standard slick, but the alternate possesses a tread compound with moderately increased grip ("softer"), making the tire faster, although possibly not quite as durable. The alternate spec Potenzas are new for Portland in 2006 as well.
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 tir es issued at a previous event. Bridgestone officials opted for the "grippier" of its two rain-tire specifications for this weekend.
Quote from Al Speyer, Executive Director, Bridgestone Motorsport: "Portland is a challenge from a circuit standpoint. It mandates a lot of grip for its many twists and curves, but it also has a couple high-speed stretches where too soft of a tire could take excessive punishment. Bridgestone has both new standard and alternate tire specs for Portland this weekend to meet those demands. They are on the 'soft' end of our road-course tire contingent, but we're confident in their consistency and durability throughout the stints. We've also brought the softer Potenza rain tire just in case we get a taste of Pacific Northwest wet weather. Whatever the conditions, it will be great to see all the competitors racing under the Bridgestone bridge on the front straight for the second straight year."
Bridgestone Pole Position Award update: Series points leader Sebastien Bourdais also is the current pacesetter in the Bridgestone Pole Position Award contest. Bourdais has taken three of the four pole positions this season, with the other going to Mario Dominguez at Houston. The pole winner at each race earns a $5,000 bonus from Bridgestone, with another $2,500 going to the Hole in the Wall Camps.
