Firestone Firehawk Race Tires Supplied:
* Primary (black-sidewall) dry-condition slicks: 804, each entry gets six sets (24 total tires);

  • Alternate (red-sidewall) dry-condition slicks: 366, each entry gets three sets (12 total tires);
  • Wet-condition (rain) tires with grooved tread pattern: 468, each entry has five sets of the street-course rain tire available this weekend.

The alternate tire program, part of the IZOD IndyCar Series since 2009, mandates a second tire specification at road- or street-course events using the same body construction as the primary specification, but with a softer tread compound to provide more grip and faster lap times while trading off compound durability in exchange for those shorter-term advantages. Firestone's alternate tires are easily identified by their bright red sidewalls.

The tread compounds for both the Edmonton primary and alternate tires are new this year, but the body construction of both remains the same as in 2010. The primary spec will also be used at Infineon Raceway next month. The alternate spec will be used again on the Motegi, Japan, road course in September. The new Firestone rain tire specification that was first available two weeks ago at Toronto will be supplied again this weekend should conditions necessitate its use.

Per series regulations, all cars must use at least one set of primary tires and one new alternate set during the race, each for a minimum of two green-flag laps. Otherwise, teams are free to use their tire allotment as they see fit over the race weekend, though a new rule for 2011 limits cars to one set of tires (team's choice of primary or alternate) for each qualifying segment.

From Al Speyer, Executive Director, Firestone Racing: "The IndyCar Series buzz continues, with people still talking about what transpired in Toronto, and that has everyone looking forward to the second Canadian event this weekend in Edmonton. Fans have embraced IndyCar racing since we've been coming to Edmonton, and the new circuit sounds as if it will be even racier and add to the excitement. Firestone is supplying primary and alternate tires with updated tread compounds to further enhance the racing. As always, tire management will be a key, especially on airport courses that are typically very bumpy and have changes in surface. Those who best 'keep their tires under them' usually have the most success. There's a great deal of momentum in this series now and we look for it to continue this weekend in Edmonton."

Firestone "Tire-ific" Move of the Race: Following each IZOD IndyCar Series race in 2011, 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 in the days after the race and vote for the nominee they believe made the most "Tire-ific" move of the race, with the top vote-getter earning the honor. The $10,000 prize from the Honda Indy Toronto on July 11 goes to Ryan Hunter-Reay for recovering from a broken front wing early in the race to finish third. Hunter-Reay will be presented his check in pre-race ceremonies Sunday.
