A worn outer shoulder has no legal consequences. The tire bed may not be damaged.

At the front tires of rear-drive vehicles, a saw-tooth-shaped wear can be partially seen. The individual blocks wear due to the slip which occurs when lifting up from the road surface due to the releasing of the inner tension. Saw-tooth-shaped wear can have an increased running noise as a result.

Different tread wear patterns form on the tires on the front and rear axles. In the interest of safety and optimal chassis conditions, an axle-wise wheel exchange is not to be recommended.
