Tyre Wear

Tread Depth

The legal limit for tread depth in the UK is 1.6mm, this must be the central ¾ of the tread and around the complete circumference of the tyre. The tyre has raised squares between the tread (see picture) to help you check the tyre without any tools. Although this is the legal limit most manufactures recommend 3mm as the wet stopping distance increases below this depth.

Tyre Wear one side

If the tyre wears on the outer edge normally it is TOE-IN to much. If the tyre wears on the inner edge normally it is TOE-OUT to much. Turning corners fast at low speed (eg car parks) can wear the N/S/F tyre on the outer edge, even if the alignment is correct.

Tyre Wear both sides

If the tyre is wearing on both edges check the suspension bushes for wear, the alignment is changing from TOE-OUT to TOE-IN as the car accelerates and brakes, see picture of worn suspension bush
