Tire replacement

under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel than the
minimum required by law.

The temperature grade for this tire
is established for a tire that is

properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.

Uniform Tire Quality Grading

Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:

Tread wear 200
Traction AA
Temperature A

Do not use retreaded tires, since
driving safety may be impaired.

This is due to the possible variations in
casing structures and, in some cases,
to their extreme age, which can lead to
a decrease in their durability.

Tire age

The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4101 indicates that the tire was
manufactured in Week 41 of the year
2001.

Although tires may have a theoretical
service life of up to 10 years, BMW
strongly recommends that you replace
all tires after an absolute maximum of
6 years.

Safety tires

Safety tires consist of self-supporting
tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of
pressure drop and driving remains
possible to a restricted degree. The
vehicle is equipped with Tire Pressure
Monitor (RDC) or Flat Tire Monitor,
which indicate a flat tire.
For additional information on Tire Pres-
sure Monitor (RDC) or Flat Tire Monitor
refer to page

Safety tires are only possible in
conjunction with Tire Pressure

Monitor (RDC) or Flat Tire Monitor.
