- When mounting tires with
unid ire ctional
t re ad design
make s ure the tread pat­

¢ page 268.
-The wheel bolts should be clean and easy
to turn. Check for d irt and corrosion on
the mat ing su rfaces of both the whee l

surfaces before remount ing the wheel.
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
int ended fo r use in a specific dir ection
When us ing a spare tire w ith a tread pattern
i ntended for use in a specific direction, please
note t he following:
- The direction of rotation is marked by an ar ­
row on the side of the tire .
-If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the t ire will not be able to
achieve its optimum perfo rma nce character­
ist ics with rega rd to aquaplaning, noise and
wea r.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weat her and
that you adjust your speed to match road
condit ions .
- Replace the fla t tire w ith a new one and
have it ins talled on your veh icle as soon as
possible to restore the handling advantages
of a unidirectiona l tire .
