Practical tips
If the tyres or rims have received a heavy im-
pact or hav e been damaged, hav
e a special-
ised w orkshop check whether or not it is nec-
essary t
o change the tyre.
Low profile tyres may deteriorate more quick-
ly than standard tyres.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration or the
car pulling to one side, this may indicate
that one of the tyres is damaged. Reduce
speed immediately if there is any reason to
suspect that damage may have occurred. In-
spect the tyres for damage. If no external
damage is visible, drive slowly and carefully
to the nearest specialised workshop and
have the car inspected.
