BMW 7 Series: 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 property. Only mount snow chains on tires that are designated by their manufacturer as suitable for the use of snow chains.
Warning
Insufficiently tight snow chains may damage tires and vehicle components. There may be a risk of accident or risk of damage to property.
Make sure that the snow chains are always sufficiently tight. Re-tighten as needed according to the snow chain manufacturer's instructions.
Fine-link snow chains
The manufacturer of the vehicle recommends the use of fine-link snow chains. Certain types of fine-link snow chains have been tested by the manufacturer of the vehicle and recommended as road-safe and suitable.
Information regarding suitable snow chains is available from a dealer's service center or another qualified service center or repair shop.
Use
Use only in pairs on the rear wheels, equipped with the tires of the following size:
- 245/50 R 18.
- 245/45 R 19.
Follow the snow chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after mounting snow chains, as doing so may result in incorrect readings.
Do not reset the Tire Pressure Monitor after mounting snow chains, as doing so may result in incorrect readings.
When driving with snow chains, briefly activate Dynamic Traction Control DTC to optimize the forward momentum.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when using snow chains
