2015 BMW X3 traction

Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire
graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passengercar tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired 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.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 204, are labeled
with a circular symbol containing the letters
RSC marked on the sidewall.
M+S
Winter and all-season tires with better cold
weather performance than summer 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 tire 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.Seite 201Wheels and tiresMobility201

Approved wheels and tires
You should only use wheels and tires
that have been approved by the vehicle manu‐
facturer for your vehicle type; otherwise, e.g.,
despite having the same official size ratings,
variations can lead to chassis contact and with
it, the risk of severe accidents
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot guarantee the operating safety of the
vehicle.◀
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.
New tires Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
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
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires pro‐
vide better winter traction than summer tires, they do not provide the same level of perform‐
ance 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 a respective symbol is displayed in your
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 respective winter tires; otherwise, tire dam‐
age and accidents can occur.◀
Run-flat tires If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Your service center will be
glad to advise you.
Rotating wheels between axlesDifferent wear patterns can occur on the frontand rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Your service
center will be glad to advise you. After rotating,
check the tire pressure and correct if needed.
Rotating the tires is not permissible on vehi‐
cles with different tire sizes or rim sizes on the
front and rear axles.Seite 203Wheels and tiresMobility203

This prevents leftover sealant from escap‐
ing from the container.4.Wrap the empty sealant container in suita‐
ble material to avoid dirtying the cargo
area.5.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
To correct the tire inflation pressure
1.Stop at a suitable location.2.Screw the connection hose of the com‐
pressor directly onto the tire valve stem.3.Insert the connector into the power socket
inside the vehicle.4.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with the ignition
turned on or the engine running, reel
on the compressor.▷To reduce the pressure: press the but‐
ton on the compressor.
Continuing the trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Reinitialize the Tire Pressure Monitor.
Replace the defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.
Snow chains
Fine-link snow chains Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
Information about the approved snow chains
are available from the service center.
Use Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷205/65 R 17.▷225/60 R 17.▷245/50 R 18.▷245/45 R 19.
No snow chains on size 245/55 R 17 tires
Do not mount snow chains on size
245/55 R 17 tires; otherwise, the vehicle may
become damaged.◀
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if needed.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/hwhen using snow chains.
