3. TWI (Tread Wear Indicator) mark on tyre
4. Rib/lug pattern
Inspect the tyre to make sure that it
has enough tread. Replace the tyre if
the tread groove depth is less than
1.6 mm. The tyres have 6 equally
spaced locations (TWI positions) that
indicate when the tread groove depth
is less than 1.6 mm. Replace the
tyres with new ones when the tyres
