Punctures are a result of sharp objects on the road e.g. screws, nails or glass which damage the tire. As a consequence the tire could lose pressure. Should you notice that one or more of your tires continuously lose pressure or you discover a screw or nail in the tread, you should visit your local tire dealer as soon as possible to get your tires checked. Continental offers a range of extended mobility systems that help to keep you mobile in the even of a tire failure.
