Schwalbe Marathon Winter HS 396 Studded Mountain Bicycle Tire Wire Bead

For a safer journey. You have full control on icy roads with the Marathon Winter. Even in tight bends and under violent braking everything remains under control. The spikes work best on ice when running at minimum pressure, while at maximum pressure the tires can be ridden on ice free roads with minimal road noise. Tires need to be run in for 25 miles 40 km on hard top road to ensure spikes are permanently fixed. Avoid rapid acceleration and braking during this period. Tungsten carbide core spikes have a wear life of several thousand kilometers.
