Digital Tyre Tread Depth Gauges

To check the tread ware of your tyres use a tread depth gauge.

The depth of the tread should be even on all parts of the tire. If you notice there is wear down the middle but not on the sides let some air out of the tyres, because they are overinflated. Conversely, if there is more wear on the sides than down the middle, re-inflate the tyres.
