How option tires will work in the NASCAR All-Star Race

The race remains basically the same – two heat races to set the starting lineup and a 200-lap main event at the historic North Wilkesboro (N.C.) Speedway that pays $1 million to the winner.

During the race, however, teams will be faced with some potentially challenging tire strategy decisions.

NASCAR and Goodyear have made three different tires potentially available for the event – a “prime tire” (the baseline tire assessed in a Goodyear tire test in March); an “option tire” (slick tires but made with the same rubber as the wet weather tire); and the “wet weather” tires (used only if the track is wet).

The ‘Goodyear Eagle’ lettering will be yellow on the prime tires, red on the option tires, and white on the wet weather tires.

“During the test, we evaluated a set-up that utilized a right-side tire with the tread compound we use on our current wet weather tire. That set-up proved to be three-tenths-of-a-second faster over our control set-up,” said Greg Stucker, Goodyear’s director of racing.

“In conversations with NASCAR, bringing an ‘option’ tire to the All-Star Race became a possibility and we had this data point to work from. With the adjustment to the wet weather compound on both the right- and left-side we expect the ‘option’ set-up to be maybe four- to five-tenths quicker than the ‘prime’ set-up, which is quite significant on a five-eighths-mile track.

“Now, with that extra grip and speed comes the fact that the ‘option’ tire will fall off more quickly, making tire management an important factor when those tires are on the car.”

Here’s a refresher on the rules for use of the different tires:

– Teams will be allotted nine sets of tires for the event weekend.

– All four tires on the car must be of the same type at all times.

– For practice, qualifying, the heat races, and the Open, teams will be allotted three sets of prime tires and two sets of option tires.

– Teams will have the choice to start on any type of tire in practice, the heats and the Open. Only the prime tire will be used during both qualifying sessions.

– For the All-Star Race main event, teams will have two sets each of primes and options. All teams will start on the option for the main event.

– NASCAR will decide if conditions warrant teams being able to utilize the wet weather tires. Teams will have a maximum of four sets of wet weather tires for the event.
