Information for your safety
The factory-approved radial tires are
matched to the car and have been se-
lected to provide optimum safety and
driving comfort on your car.
It is not merely the tire's service life, but
also driving comfort and – above all else
– driving safety that depend on the con-
dition of the tires and the maintenance
of the specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Check tire inflation pressures reg-
ularly – at least every two weeks
and before beginning a longer trip. If
this is not done, incorrect tire pressures
can cause driving instability and tire
damage, ultimately resulting in acci-
dents.<
Tire tread – Tire damage
Inspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 0.12 inches (3 mm), even
though the legally specified minimum
tread depth is 0.063 inches (1.6 mm). At
a tread depth of 0.063 inches (1.6 mm),
tread depth indicators (arrow) in the
tread-groove base indicate that the le-
gally-permissible wear limit has been
reached. Below 0.12 inches (3 mm)
tread depth, there is an increased risk
of aquaplaning, even at relatively mod-
erate speeds and with only small
amounts of water on the road.

Do not drive on a deflated (flat) tire.
A flat tire greatly impairs steering
and braking response, and can lead to
complete loss of control over the vehi-
cle. Avoid overloading the vehicle so
that the permitted load on the tires is not
exceeded. Overloading can lead to
overheating and increases the rate at
which damage develops inside the tires.
The ultimate result can assume the form
of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect,
as can variations in normal vehicle re-
sponse, such as a pronounced ten-
dency to pull to the left or right. Should
this occur, respond by immediately re-
ducing your speed and carefully pro-
ceeding to the nearest BMW center or
professional tire center, or having the
vehicle towed in to have it and its tires
inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.<
