Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance 
of the specified tire pressure are crucial not only 
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
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 increases.
Check the tire inflation pressure regularly 
and correct it as needed, even on the 
compact tire
*
: at least twice a month and before 
starting long trips. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect tire pressures, a condition that can not only 
compromise your vehicle's driving stability, but 
also lead to tire damage and the risk of an acci-
dent. Do not drive with depressurized, i.e. flat 
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking 
response. Attempts to drive on a flat tire can 
lead to a loss of control over the vehicle.

After correcting the tire inflation pressure, 
reinitialize the Flat Tire Monitor, refer to 
page
, or reset the Tire Pressure Monitor,

Pressure specifications
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 and tire brands respectively 
approved and recommended by BMW; a list 
of these is available from your BMW Sports 
Activity Vehicle Center.

For correct identification of the right tire infla-
tion pressure for your tires, observe the follow-

Maximum allowable driving speed
Tire inflation pressures for speeds 
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h, 
adjust pressures to the respective tire inflation 
pressures listed on the following pages in the 
column Traveling speeds up to max. of 
100 mph/160 km/h to achieve optimum driving 
comfort.
These pressure specifications can be found on 
the door post when you open the driver's door.
The permissible top speed for these tire 
inflation pressures is 100 mph/160 km/h. 
Do not exceed this speed, otherwise tire dam-
age and accidents may result.
