Potenza Race Tires Supplied: Bridgestone delivered 786 dry-condition ("slicks") and 320 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 slicks (28 tires) for the weekend, to use in the practice, qualifying and race sessions. The standard dry-condition specification contains the "softest" standard tire compound and construction that Bridgestone employs in the series. The same spec was first used last year at San Jose.
* 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 bright red sidewalls. At least one set (new or used) of alternates must be used for a stint in Saturday'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"), making the tire faster, although possibly not quite as durable. This alternate spec was also used in the 2006 season opener at Long Beach.
* 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, one for the faster permanent road cir cuits and another for the slower, tighter street courses. The street-course rain tire is available this weekend.
Quote from Al Speyer, Executive Director, Bridgestone Motorsport:
"It's great for Champ Car to be back in Houston, an important market that we've missed the past few years. We're extremely excited about the new track location around Reliant Park and the return of night racing to the series. The Champ Cars will be running in the afternoon, in the twilight and at night this weekend, which means track conditions could vary significantly from session to session. We're confident the Bridgestone Potenza tire choices for the weekend will perform admirably no matter the conditions. The standard-spec Potenza is our 'soft' street-course tire that's new for 2006 but did debut well last year in San Jose. We've paired it with our new alternate street-course spec that performed so well last month at Long Beach. And because this track is new to everyone, Bridgestone is making available an additional set of standard-spec tires to give the drivers more running time to familiarize themselves with the circuit. It should be a tremendous weekend."
