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
slopingwear 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 to
rapidly 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.
