What is the law relating to tyres?

Tyres should be inflated to the level set out in the car manual.

A tyre shouldn't have:

  • any of the ply or cord exposed

  • lumps, bulges or tears

  • the base of any groove, which showed the original tread pattern clearly visible.

  • a cut in it in excess of 25 mm or 10 percent of the section width of the tyre, whichever is the greater, measured in any direction on the outside of the tyre and deep enough to reach the ply or cord.

  • Any groove which showed in the original tread pattern should have a depth of at least 1.6 mm.
