Camber wear

llegal/dangerous
wear

Under-inflation has
caused this tyre to
wear on the outer
edges of the tread,
leaving the central
tread area far less
worn.

Over-inflation has
resulted in the
central tread area being forced
into contact with the
road causing rapid
centre wear and
worn shoulders.

A typical example
of the wear pattern caused by front
wheel mis-alignment,
(toe-in or toe-out).
The edge of the
tread is "feathered" and worn progressively
from one side. The
wear ridges can be felt
across the tread.

Excessive wheel
camber hascaused
sloping wear on the
outer edge of the
tread on one shoulder
of this tyre.

This tyre has been
used well after
reaching the legal
minimum pattern depth of 1.6mm.

End of life

Emergency Braking

Cuts

Impact damage

This tyre has
reached the legal
minimum pattern
depth of 1.6mm.

An emergency
braking manoeuvre with this tyre has
caused the tyre rapidly to wear
through the complete casing causing the tyre
to deflate.

Sharp objects can
cause considerable
damage rendering
a tyre unserviceable.

This is damage
caused by an
impact to the
sidewall.The bulge
or "egg" indicates localised casing damage.
