The tires are IFMAR standardized along with the wheel hex offset. The tires work countersunk center area which allows the wheel nut to hold further in wheel. The tires are perfect for high-competition battle. They work interior reinforcement ribs to provide safety and resist deformation, yet they are typically made from a flexible product generate durability and withstand outcomes. The medial part of wheel is aerodynamic for maximum performance. The tires have now been made to provide maximum traction. The tires work a 12mm inside hex. Wide range of 10 (5 set)
