Goodyear will bring its multi-zone tread tire to Richmond International Raceway for the NASCAR Sprint Cup Series this weekend, marking the first use of the technology at a short track.
The multi-zone tread will be used on right-side tires, featuring two compounds in the construction, on the .75-mile track. The inside two inches, which bear the biggest burden of heat and force, will be a more durable compound, while the outer 10 inches of the contact patch will be softer — based off the compound for last season’s Richmond races — for improved traction.
The left-side tires for this weekend’s race will be made from a new, softer compound to improve grip. This weekend’s combination of tire compounds was determined from data collected in a tire test Oct. 22-23 of last year.
The multi-zone technology has previously only been used in races at 1.5-mile intermediate tracks. The multi-zone tread made its first appearance of the 2014 season at Texas Motor Speedway on April 7; it was later used in a two-day tire test at Michigan International Speedway on April 8-9. The technology appeared in Sprint Cup races last year at Atlanta Motor Speedway and Kansas Speedway.
Saturday night’s Toyota Owners 400 (7 p.m., FOX) is the ninth of 36 points-paying races on the Sprint Cup schedule this season.
