BMW 3: Changing wheels and tires
Mounting and wheel balancing
Have mounting and wheel balancing carried out by a dealer's service center or another qualified service center or repair shop.
Wheel and tire combination
General information
You can ask the dealer's service center or another qualified service center or repair shop about the correct wheel/tire combination and wheel rim versions for the vehicle.
Safety information
Warning Wheels and tires which are not suitable for your vehicle can damage parts of the vehicle, for instance due to contact with the body due to tolerances despite the same official size rating.
There is a risk of an accident. The manufacturer of your vehicle strongly suggests that you use wheels and tires that have been recommended by the vehicle manufacturer for your vehicle type.
Warning Mounted steel wheels can cause technical problems, for instance independent loosening of the lug bolts, damage to the brake discs.
There is a risk of accident. Do not mount steel wheels.
Warning Incorrect wheel/tire combinations will have a negative impact on the vehicle's handling and on the function of a variety of systems, such as the Anti-lock Brake System or Dynamic Stability Control. There is a risk of accident. To maintain good handling and vehicle response, use only tires with a single tread configuration from a single manufacturer. The manufacturer of the vehicle recommends that you use wheels and tires that have been recommended by the vehicle manufacturer for your vehicle type. Following tire damage, have the original wheel/tire combination remounted on the vehicle as soon as possible.
Recommended tire brands

For each tire size, the manufacturer of the vehicle recommends certain tire brands. The tire brands can be identified by a star on the tire sidewall.
New tires
Tire traction is not optimal due to manufacturing 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
Warning Retreaded tires can have different tire casing structures. With advanced age the service life can be limited. There is a risk of an accident.
The manufacturer of your vehicle does not recommend the use of retreaded tires.
The manufacturer of the vehicle does not recommend the use of retreaded tires.
Winter tires
General information
Winter tires are recommended for operating on winter roads.
Although so-called all-season M+S tires provide better winter traction than summer tires, they usually do not provide the same level of performance 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 attach a label showing the permissible maximum speed in the field of view. The label is available from a dealer's service center or another qualified service center or repair shop.
With winter tires mounted, observe and do not exceed the permissible maximum speed.
Changing runflat tires
For your own safety, use only runflat tires. No spare tire is available in the case of a flat tire. Further information is available from a dealer's service center or another qualified service center or repair shop.
Rotating wheels between axles
Warning Rotating tires between the axles on vehicles with different tire sizes or rim sizes on the front and rear axles can cause damage to the tires and the vehicle. There is a risk of accident. Do not rotate the tires between the axles on vehicles with different tire sizes or rim sizes on the front and rear axles.
Different wear patterns can occur on the front and rear axles depending on individual driving conditions. The tires can be rotated in pairs between the axles to achieve even wear. Further information is available from a dealer's service center or another qualified service center or repair shop. After rotating, check the tire pressure and correct, if needed.
Storing tires
Tire inflation pressure
Do not exceed the maximum tire inflation pressure indicated on the side wall of the tire.
Storage
Store wheels and tires in a cool, dry and dark place.
Always protect tires against all contact with oil, grease, and solvents.
Do not leave tires in plastic bags.
Remove dirt from wheels or tires.

Mobility System
Concept
With the Mobility System, minor tire damage can
be sealed temporarily to enable continued travel.
To accomplish this, sealant is pumped into the
tires, which seals the damage from the inside.
Snow chains
Safety information
Warning
With the mounting of snow chains on unsuitable
tires, the snow chains can come into contact
with vehicle parts. There may be a risk of
accident or risk of damage to propert
