OverviewControlsMaintenanceRepairsDataIndex
Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety which depend on the
condition of the tires and the mainte-
nance of the specified tire inflation
pressure.
Incorrect inflation pressures are a
frequent cause of tire problems
and flat tires. Tire pressure also has a
major effect on your BMW's handling
response. We recommend that you
check the tire pressure Ð remember to
check the spare tire as well Ð before
every extended trip, as well as at least
every two weeks in normal use (refer to
page 26). Failure to observe these pre-
cautions can result in incorrect tire
pressures, which cause instable han-
dling response as well as tire damage,
and can ultimately lead to an acci-
dent.<
Tire tread Ð Tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
The tread depth should not drop
below 0.12 in (3 mm), even though, for
example the legally specified minimum
tread depth in Europe is only 0.063 in
(1.6 mm). Below a tread depth of
0.12 in (3 mm) there is an increased risk
of hydroplaning, even at relatively mod-
erate speeds and with only small
amounts of water on the road.
Tread wear indicators, refer to arrow,
are embedded around the tire circum-
ference in the base of the tire tread.
Their locations are indicated on the tire
sidewall with TWI Ð Tread Wear Indi-
cator. At a tread depth of 0.063 in 390de331
(1.6 mm) these indicators, signal that
the tires have reached the legally per-
missible wear limit.
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 vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading leads to over-
heating and causes damage inside the
tires. The ultimate result can assume
the form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. The type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the
vehicle's handling characteristics, such
as a pronounced tendency to pull to the
left or right. Should this occur, respond
by immediately reducing your speed.
Proceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it, its
wheels and tires inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.<
