The tires are IFMAR standardised using the wheel hex offset. The tires work countersunk center area allowing the wheel nut to help keep further inside wheel. The tires are particularly suitable to high-competition battle. They work internal reinforcement ribs presenting safety and resist deformation, yet they have been produced from a flexible product to make durability and withstand effects. The medial part connected with wheel is aerodynamic for maximum performance. The wheels was in fact indeed intended to offer maximum traction. The tires work a 12mm inside hex. Pair of 2 (1 set)
