Softer tire will make new IndyCar go faster at Barber
The compounds are softer (less durable) than their 2011 counterparts and were tested in November at the track. The construction has changed slightly compared to 2011 and has been designed to improve grip.
"After winning in St. Pete, Helio Castroneves was very complimentary of the direction Firestone Racing engineers have taken for 2012, noting that tires played a key role in his victory," Firestone Racing executive director Al Speyer said. "Both the primary and alternate specification Firestone tires proved to be consistent and durable in the first round, and we expect to see the same level of performance at Barber Motorsports Park this weekend."
Of note: In 2011, Will Power put 31 laps (74 miles) on a used set of alternate Firestone Racing tires en route to leading all 90 laps for a dominant victory.
