Firestone Firehawk Race Tires Supplied:

* Primary (black-sidewall) dry-condition slicks: 648, each entry gets six sets (24 total tires);

* Alternate (red-sidewall) dry-condition slicks: 318, each entry gets three sets (12 total tires);

* Wet-condition (rain) tires with grooved tread pattern: 404, each entry has five sets available as needed.

Per IndyCar Series rules, each entry must declare to the league within one hour after qualifying on which dry-condition tire spec it intends to start the race. All cars must use at least one primary set of Firehawks and one new alternate set during the race, each for a minimum of two green-flag laps. For 2009 street-course races, Firestone has three tread compound specifications available, all using the same body construction. The primary tire spec for Toronto is the most durable compound of the three. The alternate tires are identical in construction to the primaries but contain a softer tread compound to provide more grip and faster lap times. The softer alternate tires trade off compound durability in exchange for those shorter-term advantages. Firestone Racing is bringing proven tire specifications to Toronto. The same primary and alternate specs were used earlier this season at Long Beach. This marks the only time this season that identical primary and alternate tire specs will be run at two events. The Firestone rain tire this weekend is the softer "street course rain" spec.

>From Al Speyer, Executive Director, Firestone Racing: "It's great for Indy racing to return to the streets of Toronto, where it has enjoyed a great heritage. We know how passionate the Canadian fans are for their racing and Firestone Racing is excited to be back here as the IndyCar Series makes its debut. Our company has loads of winning experience on this circuit, so we're confident that the Firestone Firehawk tires will provide the assured footing necessary to make for another thrilling Toronto race weekend. We even have experience running primary and alternate tire specs here from the later days of Champ Car with our Bridgestone brand. We've seen what a difference the Firestone alternate tires have made in road and street events thus far in 2009, and we expect them to contribute that extra level of strategy, nuance and unpredictability again this weekend that has added so much to the races this season."

Firestone "Tire-ific" Move of the Race: Following each race, Firestone Racing nominates three drivers who best utilized their Firestone tires to make a bold, dramatic move during the event. Fans can go to www.indycar.com and vote for who they believe made the "Tire-ific" move of the race. Nominees from Watkins Glen were Marco Andretti, Mike Conway and Justin Wilson. The $10,000 prize winner will be announced in Sunday's pre-race activities.
