Get Mobility -> Wheels and tyres Guide for BMW X3 SUV Second Generation (2011-2017)

Mobility

Wheels and tyres

Inflating devices can display a pressure as

much as 0.1 bar too low.

Vehicle equipment

This chapter describes all standard, national

and special equipment provided in the model

series. Equipment not available in the vehicle is

therefore also described, for example the se‐

lected special equipment or national version.

This also applies to safety-relevant functions

and systems. Comply with the relevant na‐

tional regulations when using the correspond‐

ing functions and systems.

With runflat indicator: reinitialise the runflat in‐

dicator after adjusting tyre pressures.

With tyre pressure monitor: reset the tyre pres‐

sure monitor after adjusting the tyre pressure

to a new value.

Tyre inflation pressures

Tyre pressures

Information for your safety

A tyre’s condition and pressure influence the

following:

▷

Operating life of the tyre.

Driving safety.

The tyre inflation pressures specified for ap‐

proved tyre sizes are located on the door pillar

of the driver's door.

Driving comfort.

If the speed letter of the tyre cannot be found,

the tyre inflation pressure of the corresponding

size applies. The tyre inflation pressure data

apply to tyres at ambient temperature.

Checking tyre pressures

Checking tyre pressures regularly

Check tyre pressure regularly and adjust

as necessary, but at least twice a month and

before any long journey. Incorrect tyre pres‐

sures can adversely affect the car's road hold‐

ing and cause tyre damage, which could result

in an accident.◀

For Australia/New Zealand

Warning

The inflation pressures on the tyre label

are applicable only for tyres explicitly men‐

tioned on the label. Inflation pressures for tyres

that may be covered by the label – by size,

speed category and load rating/load index –

but not explicitly mentioned on the label may

be different. Please obtain adequate inflation

pressures in accordance with the tyre manu‐

facturer’s specifications at your tyre dealer.◀

Tyres have a natural, uniform tyre pressure

loss.

Tyres heat up when driving and with the tem‐

perature of the tyre, the tyre filling pressure in‐

creases. The tyre filling pressure data relate to

cold tyres or tyres at ambient temperature.

Only check the tyre pressure when the tyres

are cold. In other words, after driving for a max‐

imum of 2 km or if the vehicle has been parked

for at least 2 hours.

Mobility

Tyre sizes

Inflation pressures refer to the approved and

recommended tyre sizes and tyre makes.

Tyre damage

General

Inspect tyres frequently for damage, the pres‐

ence of foreign bodies and wear.

Your Service centre will be glad to provide

more information on wheels and tyres.

Notes

Tyre tread

Vehicle behaviour that is an indication of tyre

damage or other faults:

Summer tyres

The tyre tread depth should not be less than

3 mm, 0.12 in.

▷

Unusual vibrations while the vehicle is in

motion.

▷

Unusual vehicle response, such as pro‐

nounced pulling to the left or right.

Below a tread depth of 3 mm, approximately

0.12 in, there is a high risk of aquaplaning.

Damage can be caused by, for example, run‐

ning over kerbs, road damage etc.

Winter tyres

The tyre tread depth should not be less than

4 mm, approximately 0.16 in.

In the event of tyre damage

If there are indications of tyre damage,

reduce speed immediately and have the

wheels and tyres checked without delay, oth‐

erwise there is an increased risk of accident.

Below a tread depth of 4 mm, approximately

0.16 in, suitability for vehicle operation in win‐

ter is restricted.

Drive carefully to the nearest Service Centre.

Allow vehicle to be towed or transported there,

otherwise tyre damage can cause danger of

death to vehicle occupants and also other

road-users.◀

Minimum tread depth

Repairing tyre damage

For safety reasons, the manufacturer of

your vehicle advises against having damaged

run-flat tyres repaired; have them replaced in‐

stead. Otherwise subsequent damage cannot

be excluded.◀

Wear indicators are distributed across the tyre

circumference and have the legally prescribed

minimum height of 1.6 mm, approximately

0.06 in.

Age of tyres

Recommendation

Irrespective of wear, change tyres after

six years at the latest.

They are identified on the tyre's side wall by

TWI, Tread Wear Indicator.

Date of manufacture

On the tyre side wall:

205

Mobility

Wheels and tyres

DOT … 0115: the tyre was made in the

1st week of 2015.

Recommended makes of tyre

Replacement of wheels and

tyres

Fitting

Information on tyre mounting

Only have tyres fitted, including balanc‐

ing, by your Service centre.

Certain makes of tyre are recommended by the

manufacturer of your vehicle depending on

tyre size. These can be seen by the asterisk on

the side wall of the tyre.

If such work is performed inexpertly, it could

result in consequential damage and thus con‐

stitute a safety risk.◀

When properly used, these tyres meet the

highest standards in terms of safety and han‐

dling characteristics.

Wheel and tyre combination

The correct wheel and tyre combination and

rim designs for the vehicle can be consulted at

the Service centre.

New tyres

New tyres do not achieve their full road

grip immediately, for production reasons.

Incorrect wheel and tyre combinations will in‐

terfere with the proper functioning of various

systems, such as ABS and DSC.

During the first 300 km, 200 miles, drive mod‐

erately.

To maintain good vehicle handling, always fit

tyres of the same make and tread pattern to all

wheels.

Retreaded tyres

The manufacturer of your vehicle advises

against the use of retreaded tyres.

After a tyre has been damaged, fit the original

wheel and tyre combination again.

Retreaded tyres

Approved wheels and tyres

Due to their potentially different internal

construction and advanced age, their durability

may be limited and their road safety therefore

questionable.◀

Only use wheels and tyres that are ap‐

proved by the manufacturer of the vehicle for

the corresponding vehicle type otherwise, for

example because of tolerances in spite of the

nominal size being the same, it is possible for

contact with the bodywork to occur, resulting

in serious accidents

Winter tyres

For operation on wintry carriageways, winter

tyres are recommended.

The manufacturer of your vehicle is unable to

assess the suitability of tyres and wheels it has

not approved, and therefore cannot guarantee

their safety.◀

Although so-called all-season tyres with an M

+S marking have better winter characteristics

than summer tyres, they do not normally

match the performance of winter tyres.

206

Top speed of winter tyres

Run-flat tyres

If the car is capable of speeds higher than the

speed permitted for the winter tyres, a sticker

stating the maximum permitted speed for the

tyres fitted must be displayed in the driver's

field of view. Specialist tyre dealers and your

Service centre can supply the sticker.

Label

Top speed for winter tyres

Do not exceed the top speed for the rele‐

vant winter tyres in use, otherwise tyre damage

potentially leading to an accident could oc‐

cur.◀

RSC marking on the tyre side wall.

Run-flat tyres

These wheels consist of tyres that are self-

supporting within certain limitations, and spe‐

cial rims.

For your own safety, when using run-flat tyres,

do not mix with other types of tyre. There is no

spare wheel available in the event of a punc‐

ture. Your Service Centre will be pleased to ad‐

vise.

The reinforced side wall means that the tyre

keeps the vehicle mobile to a degree even if

tyre pressure has been lost.

Observe the information on continuing to drive

with a flat tyre.

Interchanging front and rear wheels

Different tread wear patterns arise on the

wheels of the front and rear axles, depending

on the individual operating conditions. To ach‐

ieve even wear, it is possible to swap the

wheels over from one axle to the other. Your

Service Centre will be pleased to advise. After

changing, check the tyre pressure and adjust if

necessary.

Changing run-flat tyres

For your own safety, use only run-flat tyres.

There is no spare wheel available in the event

of a puncture. Your Service centre will be

pleased to advise.

Such a change is not permitted in vehicles with

different tyre or rim dimensions on the front

and rear axles.

Remedying punctures

Safety precautions in the event of a

puncture

Tyre storage

Store wheels and tyres in a cool, dry and pref‐

erably dark place when not in use.

Park the vehicle on a solid surface and as far

away from moving traffic as possible.

Switch on hazard warning lights.

Protect tyres against contamination from oil,

grease and fuel.

Engage the steering wheel lock in the straight

ahead position of the wheels.

Do not exceed the maximum tyre pressure in‐

dicated on the tyre's side wall.

Protect the vehicle against rolling, by applying

the parking brake.

Allow all occupants get out of the vehicle and

guide them out of the danger area, for example

behind the crash barrier.

Comply with relevant local laws.◀

Sealant container

Mobility system

Principle

With the mobility system, minor tyre damage

can be quickly sealed, to allow you to drive on.

To do that, liquid sealant is pumped into the

tyres which encloses the damage from the in‐

side when it hardens.

▷

Sealant container, arrow 1.

Filler hose, arrow 2.

The compressor can be used to check the tyre

inflation pressure.

Note the use-by date on the sealant container.

valve and connect it to the free connection

on the sealant container.

This can prevent sealant residues from es‐

caping from the container.

4. Pack empty sealant container to avoid soil‐

ing in the boot.

5. Store Mobility system in the vehicle again.

Spreading sealant compound

Immediately drive for approximately

10 km/5 mi to evenly distribute the sealing

compound in the tyre.

Switch off compressor after ten minutes

Do not operate the compressor for more

than ten minutes, otherwise the device will

overheat and this could result in damage.◀

Do not exceed a speed of 80 km/h/50 mph.

If possible, do not drive slower than

20 km/h/12 mph.

Let the compressor run for approximately

three to 8 minutes to fill the sealing compound

and achieve a tyre inflation pressure of approx‐

imately 2.5 bar.

Correcting the tyre inflation pressure

1. Stop in a suitable area.

2. Bolt the connecting hose of the compres‐

sor directly onto the tyre valve.

The tyre inflation pressure may rise to approxi‐

mately 5 bar during the filling process of the

sealing compound. Do not switch off the com‐

pressor during this step.

3. Insert the plug into the socket on the inside

of the vehicle.

4. Correct tyre inflation pressure to 2.5 bar.

If it does not reach a tyre inflation pressure of

2 bar:

▷

Increase pressure: switch on the com‐

pressor with the engine running or the

ignition switched on.

1. Switch off compressor.

2. Remove the filler hose from the wheel.

▷

Reduce pressure: press the button on

the compressor.

3. Drive forwards and backwards by 10 m, ap‐

proximately 400 inches to distribute the

sealant in the tyre.

Continuing with journey

Do not exceed maximum permitted speed of

80 km/h, approximately 50 mph.

4. Re-inflate the tyre with the compressor.

Contact a Service Centre if the device does

not reach a tyre inflation pressure of 2 bar.

Reinitialise runflat indicator.

Reinitialise Tyre Pressure Monitor.

Storing Mobility system

1. Remove the filler hose of the sealant con‐

tainer from the wheel.

Have the punctured tyre and the sealant con‐

tainer of the Mobility system replaced as soon

as possible.

2. Remove the connecting hose of the com‐

pressor from the sealant container.

3. Take the filler hose of the sealant container

that was previously connected to the tyre
