Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction.
Using a spare tire with a tread pattern
intende d fo r use in a specific direction
When using a spare tire with a tread pattern
intended for use in a specific direction, p lease
note the fo llowing:
- T he direction o f rotation is marked by an a r­
row on the side of the tire.
- If the spare t ire has to be installed in the in ­
correct di rection, use the spare tire only
temporarily since the tire will not be able to achieve its optimum performance character­
ist ics with regard to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tent ion to this fact during wet weather and
that you adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed o n your ve hicle as soon as
poss ible to restore the handling advantages
of a un id irect iona l tire .
