Q405: What is the law relating to tyres?
If you are in any doubt as to whether your tyres are road worthy, take your vehicle along to a reputable garage that will be able to advise you.
The law relating to tyres is as follows, they must:
- Be suitable for the purpose of their use.
- Be inflated as to be fit for the purpose for use to which vehicle is being put (your manual will have the recommended inflation for your vehicle).
- Have no portion of the ply or cord exposed.
- Have no lump, bulge or tear caused by separation or partial failure of its structure.
- Have the base of any groove, which showed the original tread pattern clearly visible.
- Have no cut 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.
