As the tread depth reduces, the tyres ability to remove water from the road surface also reduces, increasing the risk of aquaplaning and because the tyre is unable to transmit traction and braking forces to the road as effectively the vehicles stopping distances increase.

Although the legal minimum tread depth is only 1.6 mm, Independent research at MIRA shows that tyres with 3 mm of tread have an average 25% better performance than those at 1.6 mm - which represents an extra 8 metres stopping distance in wet conditions.
