NASCAR reducing number of tires for teams at some tracks

NASCAR issued a bulletin Tuesday containing various updates to the Rule Book. The changes include a reduction in how many sets of tires a team can have for Sprint Cup races at Martinsville, Dover, Pocono, Michigan, Sonoma, Kentucky, New Hampshire Indianapolis and Watkins Glen. NASCAR cut the number of sets by one at each track for those races.

Teams will be allowed 10 sets of tires for Sunday's race at Martinsville. They'll have nine sets of race tires available at Dover, Michigan, Kentucky and Indianapolis. Teams will have eight sets of tires for both Pocono races with seven sets available at New Hampshire's July race and five race sets at Sonoma and Watkins Glen.

With a set of tires costing about $1,900, having to buy one less set will save teams teams about $20,000. NASCAR also reduced how many sets of tires teams are allowed for practice and qualifying by one set at Talladega (now allowed three sets), Daytona (three), Sonoma (four), Watkins Glen (four) and the August Bristol event (four).

This reduction will save teams about $10,000. NASCAR has not set the limits for tires for the races starting with Richmond in September through the end of the season. Those races could provide teams more savings. NBC Sports
