BMW X5: Tire chains
Safety information
Warning
With the mounting of tire chains on unsuitable tires, the tire chains can come into contact with vehicle parts. There may be a risk of accident or risk of damage to property. Only mount tire chains on tires that are designated by their manufacturer as suitable for the use of tire chains.
Warning
Insufficiently tight tire chains may damage tires and vehicle components. There may be a risk of accident or risk of damage to property. Make sure that the tire chains are always sufficiently tight. Re-tighten as needed according to the tire chain manufacturer's instructions.
Fine-link tire chains
The manufacturer of the vehicle recommends the use of fine-link tire chains. Certain types of fine-link tire chains have been tested by the manufacturer of the vehicle and recommended as road-safe and suitable.
Information regarding suitable tire 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:
- 255/55 R18.
- 265/50 R19.
- 275/45 R20.
The wheel size and rim offset are located on the inside of the wheel.
Follow the tire chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after mounting tire chains, as doing so may result in incorrect readings.
Do not reset the Tire Pressure Monitor after mounting tire chains, as doing so may result in incorrect readings.
When driving with tire chains, briefly activate Dynamic Traction Control DTC to optimize the drive power.
Maximum speed with tire chains
Do not exceed a speed of 30 mph/50 km/h when using tire chains.
