NASCAR VP of Competition Elton Sawyer joins us to discuss the "option tires" that will be available to teams during the Cup Series race in March. Those are basically a softer rubber compound that offer more grip and speed but wear out much faster.  

For the Spring NASCAR Cup Series race weekend at Phoenix Raceway, in addition to the standard "prime" Goodyear racing tires, race teams will be allotted three sets of "option" tires for use during the weekend—one set for practice, and two for the race. This is for the spring Phoenix Cup race only, not for the NASCAR Cup Series Championship race. 

As was in place for last year’s Cook Out 400 at Richmond Raceway, the prime tire will be denoted by yellow lettering; the option tire by red lettering. The option tire is made from the same compound as the oval wet weather tires. 

The allotment numbers are as such:

For the race, NASCAR will not mandate when teams use their sets. However, all four tires must match at all times. 

Some notes about the tires:
