THE POSITION OF REAR WHEEL
126
When tires are replaced, pay attention to the following points:
1. New tires should be first installed to the front
wheels and subjected to break-in operation before they are moved to
the rear wheels. Since the new tires grow during the initial period of use, adjust their inflation pressures after break-in
operation.
Break-in operation should be performed at 60 km/h (37 mph) or lower speed over a distance of more than 200 km (124
miles).
2. Use tires of the same brand, size, pattern and plies. Avoid mixed use of different types of tires, as there is a danger
of deterioration in handling and stability.
3. The difference in outside diameter between the inner and outer tires of the double tire should be limited to 12 mm
(0.47 in.) or less. If there is a difference, install the smaller diameter tire inside.
4. Since snow tires are slightly different in size
from general tires of the same size, avoid mixed use of a snow tire and
general tire as double tire.
