Mobility tyres feature a polymer liner on the inside of the tread and repel the ingress of foreign bodies that are smaller than 5 millimetres in diameter. If damage to the tread occurs, the puncture channel is instantly surrounded by the viscous sealant after the foreign body is removed and this avoids a loss of tyre pressure. Mobility tyres thus significantly increase driving safety. Problems caused by a flat tyre are reduced by up to 85%. In addition, by eliminating the spare wheel, the car weight is reduced and more luggage space is available.
