Tire condition and tire type affect motorcycle performance. Cuts or cracks in the tires can lead to tire failure and loss of motorcycle control. Worn tires are susceptible to puncture failures and subsequent loss of motorcycle control.
Tire wear also affects the tire profile, changing motorcycle handling characteristics.

Check tire conditions each day before you ride. Replace tires if tires show visual evidence of damage, such as cracks or cuts, or if tread depth is less than 1.6 Mm (0.06 In) front, 2.0 Mm (0.08 In) rear.

Note
: the ''triangle mark" indicates the place where the wear bars are molded into the tire.
When the wear bars contact the road, it indicates that the tire wear limit has been reached. Whenever you replace a tire, use a tire of the size and type listed below. If you use a different size or type of tire, motorcycle handling may be adversely affected, possibly resulting in loss of motorcycle control.

Always balance the wheel after repairing a puncture or replacing the tire. Proper wheel balance is important to avoid variable wheelto- road contact, and to avoid uneven tire wear.
