F100 FJ1 Junior Class Tire Announcement

Due to recent limited availability of new Bridgestone YLC 6.0 width rear tires, The Formula 100 Karting Series will allow the use of 7.10 width Bridgestone YLC rear tires in its FJ1 class. 7.10 width rear tires were already legal for use in the non-points FJ2 class. This means that 7.10 width rear tires are now legal for both F100 Junior classes.

As soon as availability of new Bridgestone YLC 6.0 width rear tires increases, F100 will revisit this issue and make a more permanent determination. For now, 7.10 width rear tires are legal for both FJ1 and FJ2.

The spec tire for FJ1 remains unchanged (Bridgestone YLC). FJ2 will continue to run under the "approved open tire" rule. Please see the 2015 F100 Rule Supplement for more information.
