Pneumatic vehicle tyre specially designed as a convertible spike tyre for use as a winter tyre for motorbikes, passenger vehicles and lorries

摘要

In this tyre, spikes which are attached to special carcasses and bases can be moved onto the carriageway or away from the carriageway by changing the air pressure, in order to avoid damage to carriageways which are free of snow and ice. In the application example, a tyre is described in which two treads, which are densely covered with spikes, are integrated on the outside on both sides next to the normal base. IMAGE
