Do not use retreaded tires, since

driving safety may be impaired.

This is due to the possible variations in

casing structures and, in some cases,

to their extreme age, which can lead to

a decrease in their durability.<

110nWheel and tire combinations

The right choice

Never mount wheels and tires that

have not been specifically

approved by BMW for use on your

particular model. Although other wheels

and tires may theoretically have the

same dimensions, variations in factors

such as manufacturing tolerances can

result in contact between tire and body-

work, ultimately leading to serious acci-

dents. BMW can not evaluate all tires

and wheels on the market, and is thus

unable to guarantee that the vehicle will

continue to perform safely if unap-

proved tires and/or wheels are

mounted.

The correct wheel and tire combi-

nation affects various systems

that would otherwise be impaired, for

example ABS, ATC, ASC+T/DSC and

For this reason, use only tires of the

same manufacture and tread configura-

tion. In the event of a flat tire, for

example, remount the approved wheel

and tire combination as soon as

possible.<
