DRIVE LINE
3-48
CAUTION
•
Because of their propensity to generate heat,
new tires tend to wear quickly. Install two tires
as a set on the front of the vehicle where the
load is smaller. Break in new tires by driving
200 km or more at 60 km/h or less. After this
run-in period, check tire pressure.
• If there is a difference in diameter between
inner and outer tires of a rear dual wheel, the
difference should be within 6 mm and install
the smaller tire as the inner tire.
WARNING
Be sure to use the specified type of tires and
disc wheels. Mixing bias and radial tires
results in poor steering and should be
avoided at all cost.
In addition, mixed use of different types of
tires can produce the following undesirable
effects:
• On vehicles with an ABS, the ABS system
cannot work as intended.
• The speedometer indicates a different
speed from the actual vehicle speed.
• On vehicles with a DUONIC system, the
DUONIC system (transmission) cannot
change gear at the optimum timing, so fuel
consumption becomes worse.
• The tires may touch the frame and steering
components.
• As the vehicle is driven after a wheel has
been replaced, the wheel nuts loosen up
somewhat during the early stages of driv-
ing due to “wear-in”. Therefore, it is neces-
sary to retighten the wheel nuts to the
specified torque after driving 50 to 100 km.
Thereafter, retighten the nuts at regular
intervals.
• If as a result of tire rotation, an additionally
painted face of the disk wheel mounting
face becomes the mounting face for the
mating part (wheel hub and disk wheel),
remove the paint from the mounting face of
the disk wheel and the seating face of
the wheel nut, clean these surfaces with a
wire brush or the like, and then install the
wheel.
If you use the wheel without removing the
paint, the wheel nuts are likely to become
loose because the paint film is thick.
