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
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended fo r use in a specific direction, please note
the following:
- The direction of rotat ion is marked by an arrow
on the side of the tire .
- If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora­
rily s ince the tire will not be able to achieve its
opt imum performance character istics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten­
t ion to this fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tiona l tire .
