490 Wheels and tyres

Notes on noise or unusual handling charac‐
teristics
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tyres are damaged. If you suspect that a tyre is
defective, reduce your speed immediately. Stop
the vehicle as soon as possible to check the
wheels and tyres for damage. Hidden tyre dam‐
age could also be causing the unusual handling
characteristics. If you find no signs of damage,
have the tyres and wheels checked at a qualified
specialist workshop.
