2015 BMW Z4 winter tires

car tires must meet 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.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.◀
RSC – Run-flat tires The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
page 234.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
XL
Designation for specially reinforced tires.
Tire tread
Summer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Indications of tire damage or other vehicle de‐
fects:
▷Unusual vibrations during driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels and tires checked right away; other‐
wise, there is the increased risk of an accident.
Drive carefully to the next service center or tire
shop.

Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
Retreaded tires The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do
provide better winter traction than summer tires, they do not provide the same level of per‐
formance as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field
of vision. You can obtain this sign from the tire
specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the winter tires; otherwise, tire damage and ac‐
cidents can occur.◀
Run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
Your service center will be glad to advise you.
Rotating wheels between axlesThe manufacturer of your vehicle advises
against swapping wheels between the front
and rear axles.
This can impair the handling characteristics.
Rotating the tires is not permissible when us‐
ing different types of tires.
Storage Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Snow chains Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your service center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufactur‐
er's instructions when mounting snow chains.
Do not exceed a speed of 30 mph/50 km/h
when using snow chains.
Do not initialize the Flat Tire Monitor if snow
chains are mounted; otherwise, the instrument
might issue an incorrect reading.Seite 235Wheels and tiresMobility235
