Random tyre inspections in 2016


During the period from August 29 until September 2, 2016, random tyre inspections were carried out in different parts of Sweden.

How random tyre inspections are done

The tread depths and inflation pressures that are checked during the random inspections is recorded. The results forms the basis of a random tyre inspection report.

On a wet road surface, when tyres are worn to under 3 mm (0.1 in.), braking distance and the risk of aquaplaning increase considerably.

Little awareness of tread depth and
inflation pressure

During random tyre inspections in previous years, almost every third car had at least one badly worn tyre (3 mm/0.1 in. of tread or less). The remarkable thing was that only one driver in ten was aware that his/her car had one or more badly worn tyres. Previous results also indicated that two of three drivers had not checked inflation pressure during the past month or did not know when this had been done most recently. Under-inflation causes the tyres to wear prematurely and increases fuel consumption. Furthermore, poorly inflated tyres make the car difficult to control in a critical situation. The risk of punctures also increases.
