Tyres and the Law
Tyres must be fit for purpose. Therefore, free from any defects and correctly inflated to the recommended pressure.
In the eyes of the law, fit for purpose means that a tyre must be:
- compatible with the types of tyres fitted to the other wheels
- free of any lump, bulge or tear caused by separation or partial failure of the structure
- free of any cut or tear in excess of 25mm or 10% of the sectional width of the tyre, whichever is the greater, and which is deep enough to reach the ply or cord without any part of the ply or cord exposed
Tyres must also have a minimum of 1.6mm of tread depth across the central three-quarters of the tyre’s width. However, this should be in a continuous band around the entire circumference.
