Tire Friction
When tire tread wear exceeds the use limit, the tire becomes more susceptible to punctures and failure�
An accepted estimate is that 90% of all tire failures occur during the last 10% of tread life, so it is unsafe to
continue to use tires until they are bald� In accordance with the Periodic Maintenance Chart, measure the
depth of the tread with a depth gauge, and replace any tire that has worn down to the minimum allowable
tread depth�
Visually inspect the tire tread for cracks and cuts, and replace with a new tire if severely damaged� For
example, if partial expansion appears on the tire, it means the tire is severely damaged�
Remove any embedded stones or other foreign particles form the tread�
CAUTION
When the environment temperature is below 14°F (-10°C), it is recommended to place the vehicle indoors
if required to store for a long time�
Do not use side stand to park vehicle for long time in winter� Use the middle stand (if equipped) or park
stand bracket to park the vehicle, as the tires should not bear the vehicle weight�
Do not allow the tires to sink into snow or ice when parking the vehicle in winter�
When parking vehicle for long time outside in winter, use a ground covering under tires that will insulate
and protect them�
