Volkswagen Golf Service & Repair Manual: Measuring tread depth

Volkswagen Golf Service & Repair Manual / Wheels and Tyres Guide - General Information / Tyre wear / Measuring tread depth

Note

The tread depth is measured in the main tread channels.

Do not measure at the TWIs (Tread Wear Indicators).

Measure the tread depth in the main tread channel, at the points where the tyre is worn most heavily. The position of the TWIs can be seen at various points on the shoulder of the tyre → Item.

A “Δ” or the manufacturer's “logo” may appear in the place of “TWI”.

The bars of the TWI have a height of 1.6 mm. This is the minimum tread depth required by German law.

Different values may apply in other countries.

Measuring tread depth

The TWIs must not be included in the measurement. Tread depth should always be measured at the deepest point of the tread channel.
