NASCAR Phoenix tire testing completed

Five NASCAR Sprint Cup Series drivers – Johnson, Edwards, Stewart, Kurt Busch and Kyle Busch – completed a two-day Goodyear tire test at Phoenix International Raceway on August 29-30. The tests ran from 6:30 a.m. to 2:30 p.m. each day and provided NASCAR's official tire manufacturer with data and feedback on PIR's new racing surface following the August 12 completion of the track's first major paving project since 1990. The research gathered from the tests will assist Goodyear in selecting a tire for the Kobalt Tools 500 NASCAR Sprint Cup Series race at PIR on November 13. In February, Phoenix International Raceway announced details related to the 47-year old NASCAR facility's first major track pavement project since 1990. Construction began in March with the removal of the facility's former racing surface and the subsequent installation of a new race track. Monday and Tuesday's tests offered all five drivers their first runs on a new surface that included a series of changes implemented to promote side-by-side racing. One such change, the alteration of PIR's signature back-stretch dog-leg to include banking and elevation variances, improved what Kurt Busch referred to as the "fun factor" at PIR.
