Potenza Race Tires Supplied: Bridgestone delivered 766 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 seven sets of standard specification slicks (28 tires) for the weekend, to use in the practice, qualifying and race sessions. For San Jose, Bridgestone brought the same primary tires used on the streets of Houston and Toronto earlier this season.
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 tire for San Jose is the same Potenza that was used as the alternate spec in Long Beach, Houston and Toronto in 2006.
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 its "softer," or higher-grip rain-tire specification for this weekend.
Quote from Al Speyer, Executive Director, Bridgestone Motorsport:
"Last weekend in Edmonton proved that sometimes tires can make all the difference between winning and losing. We watched as Justin Wilson dominated on the standard-spec tires while his opponents gave chase on the alternates. Bridgestone Motorsport and its engineers have been working hard on the alternate tire concept, and we are pleased with the results so far. The Bridgestone reds could once again play a very important role in the outcome this weekend in San Jose, as tight street circuits can make for difficult passing. Drivers and teams will certainly be looking hard for every advantage. I know that there has been a lot of effort invested in track improvements since last year's inaugural event, and Bridgestone is looking forward to putting our Potenzas to the test on the new configuration."
