Tire inflation pressure
Information for your safety
It is not merely the tires' service life, but also 
driving comfort and, to a great extent, driving 
safety that depend on the condition of the tires 
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly 
and correct it, if necessary: at least twice a 
month and before starting long trips. If you fail 
to observe this precaution you may be driving 
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive 
with deflated, i.e. flat tires, except when using 
Run-Flat Tires. A flat tire will seriously impair 
your vehicle's handling and braking response. 
Attempts to drive on a flat tire can lead to loss of 
control over the vehicle.

Checking pressure
Only check tire inflation pressure when the 
tires are cold. This means after a maximum of 
1.25 miles/2 km driving or when the vehicle has 
been parked for at least 2 hours. When tires are 
warm, the tire inflation pressure is higher.
After correcting tire inflation pressures, 
always reinitialize the Flat Tire Monitor, 
refer to page

Inflation pressure specifications for 
factory-installed tires
The inflation pressures for your factory-
installed tires at ambient temperature can be 
found on the door post when you open the 
driver's door.
Inflation pressure specifications for 
other tire sizes
The tables below provide all the correct inflation 
pressures for the specified tire sizes at ambient 
temperature.
The inflation pressures apply to the tire 
sizes approved and tire brands recom-
mended by BMW; a list of these is available 
from your BMW center.

Maximum allowable driving speed
Tire inflation pressures for driving up to 
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h 
adjust pressures to the respective tire inflation 
pressures listed on the following pages in the 
traveling speeds column for normal driving at 
speeds up to a maximum of 100 mph or 
160 km/h to achieve optimum driving comfort. 
The maximum permissible speed for 
these tire pressures is 100 mph or
