Vehicles on which the tires have been provisionally sealed are subject to new permissible maximum speeds and maximum driving distances. Country-specific repair restrictions must be observed.
If the above prerequisites are not satisfied or if the object which caused the tire damage cannot be found or if there is any other uncertainty or doubt whatsoever, provisional sealing must not be performed.
Hidden structural damage could result in premature failure of the tire.
