What you need to know

The highway code states that:

"Tyres MUST be correctly inflated to the vehicle manufacturer’s specification for the load being carried. Always refer to the vehicle’s handbook or data. Tyres should also be free from certain cuts and other defects.

Cars, light vans and light trailers MUST have a tread depth of at least 1.6 mm across the central three-quarters of the breadth of the tread and around the entire circumference."

What does this mean for your safety?

The chart on the right shows the approximate wear at given tread depths. The LEGAL limit is 1.6mm of tread, however, at 3mm tread remaining stopping distances dramatically increase, especially in the wet as the tyre can no longer clear as much water from the road surface which can lead to aquaplaning.

Just as dangerous as worn tyres are incorrectly inflated tyres that can lead to poor traction and instability of the vehicle, especially through cornering and braking.


To comply with current law, as well as the minimum tread depth, tyres should:

Be compatible with the types of tyres fitted to the other wheels

Not have any lump, bulge or tear caused by separation or partial failure of the structure.

Not have a 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.

Not have any part of the ply or cord exposed
