Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
In a very real sense, both tire life and
your own safety are riding on correct
tire specifications and inflation pres-
sures, refer to page 26.
Incorrect tire inflation pressure is
a frequent cause of tire damage. It
also significantly influences the road-
holding ability of your BMW. Be sure to
check the tire inflation pressures,
including the spare tire, on a regular
basis, at least twice a month and before
doing any extended driving, refer to
page 26. If this is not done, incorrect
tire pressures can cause driving insta-
bility and tire damage, ultimately
resulting in accidents.<
Check the inflation pressure of
the spare tire For checking tire pressures, there is a
valve extension (arrow) on the storage
tray of the spare wheel which is acces-
sible from outside.367de309
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 pattern depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is 0.063 in (1.6 mm). Tread wear
indicators (arrow) are embedded in the
base of the tire's tread. Their locations
are indicated by the legend TWI Ð Tread
Wear Indicator Ð at various points on
the tire's shoulder. When the tread
reaches a depth of 0.063 in (1.6 mm),
these indicators appear to signal that
the tires have worn to the minimum
legal level. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively 390de331
