Wheels & Tyres
This ATV is equipped with low pressure tubeless tyres. Although the
tyres are designed specifically for off-road use, they are not immune
to punctures. Always select your riding area with care.
The following pages give detailed information on how and when to
check your air pressure, how to inspect your tyres for wear and
damage, and our recommendations for tyre repair and replacement.
Air Pressure
Refer to Safety Precautions on page 113.
Properly inflated tyres are most important for safety, and will provide
the best combination of handling, tread life, and riding comfort.
Generally, underinflated tyres wear unevenly, adversely affect
handling, and are more likely to fail from being overheated.
Overinflated tyres make your ATV ride harshly, are more prone to
damage from surface hazards, and wear unevenly.
Make sure the air valve caps are secure. If necessary, install new
caps.
