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 if necessary, including on the 
spare wheel
*: at least twice a month and before 
starting long trips. Otherwise, driving instability 
or tire damage, and therefore accidents, can 
result from incorrect tire inflation pressures.<
After correcting the tire inflation pressure, 
reinitialize the Flat Tire Monitor, refer to 
page85, or reset the Tire Pressure Monitor, 
refer to page87.<
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 center.<
For correct identification of the right tire infla-
tion pressure for your tires, observe the follow-
ing:
>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving 
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 for traveling speeds up to a 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.<
Tire inflation pressures for driving 
above 100 mph/160 km/h
In order to drive at maximum speeds in 
excess of 100 mph/160 km/h, please 
note the tire pressures for speeds exceeding 
100 mph/160 km/h listed in the relevant column 
of the table on the following pages and adjust 
your tire inflation pressures as needed. Other-
wise, tire damage and accidents could occur.<
Observe all national and local maximum speed 
limits, otherwise violations of the law could 
occur.
