The tires are IFMAR standardized aided by the wheel hex offset. The tires work countersunk center area that allows the wheel nut to remain deeper in wheel. The tires are ideal for high-competition battle. They work interior reinforcement ribs to supply security and resist deformation, yet these are typically produced from a flexible item to provide durability and withstand effects. The medial side of wheel is aerodynamic for optimum performance. The tires had been designed to offer maximum traction. The wheels work a 12mm interior hex. Pair of 10 (5 set)
