Wot-Nots Tyre Tread Depth Gauge – Analogue (PWN1017)

Description

Genuine Wot-Nots · Part no. PWN1017

The Wot-Nots Tyre Tread Depth Gauge – Analogue (PWN1017) is a small metal and plastic gauge, sold as a single, that measures how much tread is left in a tyre's grooves. It marks the 1.6mm legal limit, so you can see at a glance whether a tyre is close to needing replacement before an MOT or a long trip.

Good to know

• Where do I measure? Check the main grooves across the central part of the tread and at several points round the tyre, as wear is rarely even; the legal minimum for cars is 1.6mm across the central three-quarters of the tread, all the way round.
• Should I wait for the legal limit? No, wet grip and stopping distances get noticeably worse well before then, so plan new tyres while there is still some margin, especially before winter.
• What else can the gauge tell me? Compare inner and outer edges: wear on both edges suggests low pressure, wear in the centre suggests too much, and wear on one edge points to tracking or alignment that needs checking.
