Crate Racin’ USA Officials have updated/amended the tire limit for this weekend’s “King of the Hill” event at Thunderhill Raceway Park in Summertown, TN. Competitors will be allowed 6 total tires for the event, one more than the mandated 5 issued for touring events through the end of 2021.
The 4 tires used for Qualifying, Heat Races, and B-Mains will be marked in pre-race tech. Two additional tires will be allowed for the Feature event on Saturday. Any other tires changed would result in the competitor starting on the tail of the next event whether that be a Heat Race, B-Main or Feature event. Flat tires can be changed during the feature which will also result in being sent to the tail of the field.
If a tire is flat or punctured, competitors will be allowed to replace that tire with a used tire that is approved by Series’ officials to allow them to retain their starting spot. Tire must be presented to series officials and approved/marked for competition.
Also, the Hoosier HTS 1350 and HTS 1600 tire option will be allowed with the Hoosier Crate Racin’ USA D-21 and D-55 through the remainder of the 2021 season. A two-week burn off will be allowed after December 31st to allow tires to be used. This will be in effect for Touring and Weekly Racing Series events.
We appreciate everyone working with us and will post any future updates when necessary.
