The "Turbo" of spike tires, this model is described as lighter, grippier, and faster. Up to 402 spikes made of aluminum and tungsten carbide cores remain light while biting firmly into icy paths and roads, maintaining agility and handling. New studded tires require a bed-in period. Run the tires for approximately 40 km (25 miles) on asphalt without heavy acceleration or braking so the studs are fully set. After this distance, the tires can be ridden normally.
