A Question Of Statistics: Influence Of Tyre Pressure On Traffic Safety

Three percent of all traffic accidents in Germany occur due to technical defects on the cars, more than half of which are tyre defects; in total round about two percent of all accidents are due to the tyres. This figure seems to be reassuring, but they apply only to accidents caused directly and undoubtedly from the tyres – for example a puncture. The question “what was the reason for the puncture?” – maybe a long-term inner defect – is never asked.

In the common statistics no hint is given on the influence of reduced tyre pressure on traffic safety. Nobody can give information about how many accidents happened because of faulty steering or below-standard characteristics in bends or hydroplaning safety. Also accidents involving stationary vehicles parked on the street are not counted in the statistics.

Collisions with “objects” on the roads are mentioned, but the objects are not specified. Very often these “objects” are tyres or parts of tyres, which can be a very dangerous obstacle – especially when the objects are truck tyres. For the statistics regarding accidents caused by faulty tyres it is still correct what was mentioned in an analysis in 1985 – and it sounds ironical: one result of the report is that it is not possible to make concrete declarations about the reasons for accidents.
