238 Wheels and tyres
For technical reasons snow chains may only be used on tyres with
certain wheel rim/tyre combinations.
Rim size Rim offset
8.5Jx18 29 mm
8.0Jx18 31 mm
Only use snow chains with fine-pitch links. The links must not
protrude more than 13.5 mm from the tyres (including tensioner).
Remove the chains when roads are free of snow. Otherwise they will
impair handling, damage the tyres and wear out very quickly.
where snow chains are compulsory on certain roads, this normally
also applies to cars with four-wheel drive. Snow chains may only be
fitted to the front wheels (also on vehicles with four-wheel drive).
Tyre size
