Tyres - tread wear indicators

Tread wear indicators show the status of the
tyre's tread depth.
Tread wear indicators.
A tread wear indicators is a narrow elevation
across the longitudinal grooves of the tyre's tread
pattern. On the side of the tyre are the letters
TWI (Tread Wear Indicator). When the tyre's tread
depth is down to 1.6 mm, the tread will be level in
height with the tread wear indicators. Change to
new tyres as soon as possible. Remember that
tyres with little tread depth provide very poor grip
in rain and snow.
