Tyre damage
Unusual vibration while the car is being driven
could indicate a tyre fault or some other defect
on your car. This may have been caused e.g. by
driving over a kerb or similar. The same applies
to any other abnormal road behaviour, such as
pulling severely to the right or left.
In such cases, reduce speed immediately
and have the wheels and tyres checked
without delay. Proceed with caution to the near-
est BMW Service or specialist tyre dealer that
operates to BMW specifications and has suita-
bly trained personnel. Have the car towed there
if necessary. Tyre damage represents a risk of
serious injury to occupants and to all other road
users.
<
Age of tyres
For a variety of reasons, including the tendency
of tyres to become brittle along with increasing
age, BMW recommends that new tyres be fitted
after not more than 6 years, irrespective of the
actual level of wear. This also applies to the tyre
on the compact wheel
*
.
A tyre's date of manufacture is included in the
inscription on the tyre:
DOT ... 1207 means that the tyre was manufac-
tured in week 12 of 2007.
Run-flat tyres
The symbol identifying run-flat tyres is a circle
with the letters RSC on the side wall.
Run-flat tyres comprise a tyre that is self-sup-
porting within certain limitations, and a special
rim. The reinforcement in the side walls ensures
that the tyre can continue to be used subject to
certain restrictions, even if depressurised.
If you need to continue driving with a damaged
tyre, see Indication of a flat tyre, page
87 .
New wheels and tyres
Have new wheels and tyres fitted only by
BMW Service or by a specialist tyre dealer
that operates to BMW specifications and has
suitably trained personnel. If such work is per-
formed inexpertly, it could result in consequen-
tial damage and thus constitute a safety risk.
Make sure that the new wheels are balanced.
<
Retreaded tyres
BMW advises against the use of
retreaded tyres, as these could adversely
affect the car's safety. Their carcasses may dif-
fer in internal construction or have aged suffi-
ciently to limit their durability.
<
The correct wheels and tyres
When fitting new tyres or changing over from
summer to winter tyres and vice-versa, for your
own safety you should fit run-flat tyres. BMW
Service will be pleased to advise you on this.
For safety reasons, BMW recommends
that damaged run-flat tyres be replaced
rather than repaired. <
BMW recommends fitting only wheels
and tyres that it has approved for your
type of vehicle, otherwise the tyres may e.g.
make contact with the vehicle body due to
impermissible tolerances, even though they are
of an approved size; this could result in a serious
accident. BMW is unable to assess the suitabil-
ity of wheels and tyres it has not approved and
cannot therefore guarantee their safety.
<
When fitting larger wheels and tyres, it
may be necessary to have the wheel arch
linings modified, to avoid endangering road
users or damaging the car itself. Always have
this work performed either by BMW Service or
by a workshop that operates to BMW specifica-
tions and has suitably trained personnel.
