Photos: Phoenix using ‘Tire Dragging Machine’ to create groove

The Kobalt Tools 500 will showcase the second to last race in the Chase for the NASCAR Sprint Cup on the newly repaved and reconfigured one-mile oval at Phoenix International Raceway. To prepare the new surface, PIR has implemented a month-long program to groom the track. One of the techniques that is being utilized is an advanced tire dragging machine that will focus on enhancing the upper groove of the race track by applying rubber into the surface. Track officials are pleased with the early results and are confident that the grooming will produce excellent results in advance of the race teams arrival for the Kobalt Tools 500.
