Tire replacementAlways use the same size and type of tires
recommended in this owner’s manual. The
tires that came with your Yamaha Viking were
designed to match the performance capabili-
ties and to provide the best combination of
handling, braking, and comfort. It is best to re-
place all four tires at the same time. If that is
not possible, you must replace the tires in
pairs (front or rear) with tires of the same size
and type as the originals. Never replace just
one tire.
WARNING
Installing improper tires on your Yamaha
Viking can affect handling and stability.
This can cause a loss of control.
The tires listed below have been approved by
Yamaha Motor Manufacturing Corporation of America for this model.
Front tire:Size: 25 × 8-12NHS
Manufacturer/model:
MAXXIS/MU09
Rear tire: Size:
25 × 10-12NHS
