Teams allowed to purchase extra set of tires for Homestead

NASCAR sent a memo to Cup teams Saturday morning that they can purchase an extra set of tires for Sunday's season finale at Homestead-Miami Speedway.

Cup teams now will be allowed 10 sets for the race plus the set they start on. Last year, teams were allowed 12 sets plus the set they started on.

The move comes as Cup title contenders raised concerns about the tire limit for this race.

Teams were allowed fewer tires in half of the playoff races this season compared to last year. NASCAR cut allotments for some races after examining tire usage by teams with Goodyear. NASCAR sought to have the number of sets available closer to what had been used in previous races.
