Refer to Safety Precautions on page 123.
Properly inflated tires provide the best combination of handling,
tread life, and driving comfort. Generally, underinflated tires wear
unevenly, adversely affect handling, and are more likely to fail from
being overheated. Overinflated tires make your Honda SXS drive
harshly, are more prone to damage from surface hazards, and wear
unevenly.
Make sure the valve stem caps are secure. If necessary, install new
caps.
