Martinsville Speedway Wednesday announced a new tire rule for the ValleyStar Credit Union 300 late model feature a week from Saturday night. This year, teams will have options on new tires. Teams will start the main event on tires used in the qualifying races and will then have four fresh tires available for the feature race. The race will be stopped at Lap 100 and on Lap 180. You can put on those fresh tires at either lap or split the allotment, you can also add up to 10 gallons of fuel at both stops. The winner takes home 25 thousand dollars.
