Even modern winter tires can sometimes be of little help when there are huge amounts of snow and steep gradients. In these situations, traction, lateral control and reliable braking require tire chains. In order to be prepared, it is recommended to try and fit chains in a “dry run.”
Snow chains have to be draped over the drive wheels.
Please also note that a maximum speed is given. With some low profile tires a problem can result: the reduced space between the tires and the wheel arch leaves no room to fit snow chains.
