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
Over-inflation has resulted in the central tread area being forced into contact with the
road causing rapid centre and worn shoulders.
Mis-Alignment
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 by drawing a hand across the tread.
Camber wear
Excessive wheel camber has caused sloping wear on the outer edge of the tread on one
shoulder of this tyre.
Illegal/dangerous wear
This tyre has been used well after reaching the legal minimum pattern depth of 1.6mm.
End of life
This tyre has reached the legal minimum pattern depth of 1.6mm.
Emergency Braking
An emergency braking man - oeuvre with this tyre has caused the tyre to rapidly wear
through the complete casing causing the tyre to deflate.
Cuts
Sharp objects can cause considerable damage rendering a tyre unserviceable.
Impact damage
This is damage caused by an impact to the sidewall. The bulge or "egg" indicates
localized casing damage.
