What the minimum legal limit that a tyre's tread depth must be? Gustav 22-Feb-2013

Question:

Good afternoon Could you please tell me what the minimum legal limit that a tyre's tread depth may be for it to be roadworthy.

Answer:

In terms of Regulation 212 of the National Road Traffic Act it states that no person shall operate on a public road a motor vehicle which is equipped with a regrooved tyre having a bead diameter of 430 millimetres / less. The law says your tyres must have at least a 1 millimetre tread and if it falls below that figure, you risk hefty fines and points on your licence. Some tyres have tread wear indicators in the tread pattern to show when the tread depth is less than 1.6 millimetres. In these cases, if the tread on the tyre is level with these indicators, the tyre must be replaced as it is considered unroadworthy.
