How Effective?

  • Tyres are a crucial component of a vehicle’s safety system. They are the vehicle's only point of contact with the road, and must be in a legal condition in order to perform properly.

  • There is relatively little data about the number of accidents or casualties caused by tyres in poor condition, but the Police Contributory Factors database indicates that over the 5 year period from 2012 to 2016, 96 people were killed in accidents in which the police judged the condition of the vehicle tyres to have been a contributory factor. (RRCGB, DfT, 2017)

  • In 2012/13, 7.7% of cars, 3.8% of large passenger vehicles, and 7.2% of goods vehicles failed the MoT test due to a fault with their tyres, or only passed the test after a tyre defect was rectified. Also, 3.5% of motorcycles failed the MoT test due to a fault with their tyres or wheels, or only passed the test after a tyre or wheel defect was rectified.

  • Lower tyre tread depths increase stopping distances in wet conditions on both asphalt and concrete surfaces.

  • Regular tyre pressure checks have been associated with reduced odds of being seriously injured in a crash

  • In Scandinavian countries, studded tyres resulted in minor declines in automobile accident rates of 5% on snow or ice covered roads, 2% on dry and wet roads, and 4% on all road surfaces combined. However, no research was found which compared accident rates between vehicles with and without central European winter tyres, and studded tyres are not normally legal to use in the UK.
