Owner Maintenance
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset
(inset/outset).
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.
