This is a pair of rear World GT Spec tires from John's BSR Racing.
This is one of the two brands of tires that are allowed as per the
official World GT rules.
BSR foam tires are at the forefront of current tire construction technology and continue to make improvements to keep BSR as one of the best tires on the market. BSR only uses the best and freshest high quality foam to construct their Foam Tires. Strict guidelines and measures ensure that all tires leaving the BSR factory remain constant and reliable.
BSR continues to guarantee a no split seam! BSR’s seam-glue prevents this from ever happening... no matter what type of tire traction that you use. BSR replaced the original wrapped style donut design with the laminated and waterjet cut style donuts to ensure consistent performance. This style donut allows BSR to offer their dual-compound tires which have became very popular.
These are the same tires as the CLN2302 CRC Racing tires.
