BIRMINGHAM, Ala. -- Verizon IndyCar Series teams will benefit from new regulations regarding Firestone tire allotment written into the 2014 series rulebook. Each entry will receive credit for new tires remaining from its race event allotment.

“We thought, ‘What happens to all those tires that are left from an event?’ ’’ INDYCAR president of competition and operations Derrick Walker said. “Firestone worked with us to get this into place.”

• After a street course event, one set of new primary tires remaining may be carried forward to a future street course event and added to the entry’s allotment.

• Any remaining new tires from an entry’s event allotment may be added to the entry’s test allotment. Remaining new sets of alternate tires will be returned to the entrant as primary tires. Each entry is permitted a total of 54 sets of tires (primary or wet) for their 18 test days through the end of the season, and the carryover tires must be the correct specification for the circuit.

Example: An entry receives credit for its three sets of tires remaining from the March 28-30 Firestone Grand Prix of St. Petersburg to carry forward one set of primary tires to the April 11-13 Toyota Grand Prix of Long Beach and two sets for a future test day.

• Teams may carry forward two sets of tires from the Barber Open Test to a future Open Test or a team test.

Barber Motorsports Park in Birmingham, Ala., which hosts the Honda Indy Grand Prix of Alabama on April 26, is hosting spring training March 17-18. The next Open Test is April 30 on the reconfigured Indianapolis Motor Speedway road course in preparation for the inaugural Grand Prix of Indianapolis on May 10. Auto Club Speedway will host an Open Test on Aug. 27 in advance of the 500-mile season finale under the lights Aug. 30.

• With the exception of superspeedway events, entries completing five or more laps during practice Session 1 will earn an additional set of primary tires for the event.
