Practical Tyre Condition Check

Checking tyre condition takes seconds and requires no special tools. A pocket coin measures groove depth at home, and the sidewall code reveals the tyre's true age.

Measuring tread depth

Choose whether to measure using a pocket coin or a standard matchstick.

1. Locate the groove

Locate the main longitudinal groove in the centre of the tyre, not the outer shoulder.

2. Position the tool

Insert the coin vertically along the groove channel so its outer edge rests at the bottom.

3. Check the reading
