Direction of rotation
Tires with a specified direction of rotation have additional benefits, e.g. if there is a risk of hydroplaning. You will only gain these benefits if the correct direction of rotation is maintained.
An arrow on the sidewall of the tire indicates its correct direction of rotation.
You may mount a spare wheel/emergency spare wheel against the direction of rotation.
Observe the time restriction on use as well as the speed limit specified on the spare wheel/emergency spare wheel.
