Tire inflation pressure

124n
Information for your safety
The factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
It is not merely the tire's service life, but
also driving comfort and – above all
else – driving safety that depend on the
condition of the tires and the mainte-
nance 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 the tire inflation pressure –
for the space-saver spare tire or
spare tire – on a regular basis (refer to
page 28), at least twice a month, and
before starting out on any extended
trip. If this is not done, incorrect tire
pressures can cause driving instability
and tire damage, ultimately resulting in
an accident.<

Tire condition

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 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At a
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base indicate that the wear
limit – applicable by law throughout
Europe – has been reached. Below
0.12 in (3 mm) tread depth, there is an
increased risk of aquaplaning, even at
relatively moderate speeds and with
only small amounts of water on the
road.
Never continue driving 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 can lead to
overheating and increases the rate at
which damage develops inside the
tires. You could have a blowout as a
result.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
The same applies to irregularities
related to your usual driving style, such
as pulling hard to the left or right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed
carefully to the nearest BMW center or
professional tire center, or have the
vehicle towed in to have it and its tires
inspected.
Tire damage (up to and including
sudden and complete air loss) can
endanger the lives of both the vehicle
occupants and other road
