Tires age even if they have not been used or have only been used
occasionally. Cracking of the tread & sidewall rubber, sometimes accompanied
by carcass deformation, is evidence of ageing. Old & aged Tires must be
checked by a tire specialist to ascertain their suitability for further use.
Tires fitted to vehicles such as caravans & boat trailers which are parked for
long periods will tend to age & crack more quickly than those which are used
& run frequently. In such circumstances it is important to jack the weight off
the Tires & to cover them so that they are protected from direct light.
Particular attention must be paid to spare Tires which may be old or aged in
which case they should be used with caution & be replaced as soon as possible.
