1 The original tyres have tread wear safety bands (B), which will appear when the tread depth reaches approximately 1.6 mm. The band positions are indicated by a triangular mark on the tyre sidewall (A)
2 Alternatively, tread wear can be monitored with an inexpensive device known as a tread depth indicator gauge
3 Tyre shoulder wear is caused by under-inflation, incorrect wheel camber (worn suspension parts) or hard cornering
4 Tyre centre wear is caused by overinflation
5 Uneven tyre wear is caused by unbalanced wheels, worn/broken suspension parts or incorrect wheel alignment
