- Pull the reversible blade from the screwdriv-
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
- When mounting tires with unidirectional
tread design make sure the tread pattern is
pointed the right way ¢ page 264.
- The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be-
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design mus t 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 tire with a tread pattern in-
tended for use in a specific direction, please note
the following:
- The direction of rotation 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 since the tire will not be able to achieve its
optimum performance characteristics with re -
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten -
tion 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-
tional tire.
Notes on wheel changing
Please read the information ¢ page 243 if you
are going to use a spare tire which is different
from the tires on your vehicle.
