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