Tires

WARNING
Operating the motorcycle with incorrect tires, incorrect tire pressure or excessively worn tires could cause loss of control or accident. Underinflation can cause a tire to overheat and result in a tire failure. Only use tires approved by Indian for the model of the motorcycle. See your dealer. Use of unapproved or an improperly mixed front and rear tire can result in decreased handling performance and stability, potentially leading to reduced control of the motorcycle. Always maintain proper tire pressure as recommended in the rider’s manual and on safety labels.

Tire Pressure

Improper tire pressure can result in irregular tire wear, tire failure, reduced fuel economy and a poor riding experience. It can also affect handling and stopping ability.
Slow tire pressure loss over time is normal for a functional tire. Although a tire pressure monitoring system (TPMS) will alert the user to a low pressure condition (if equipped), always inspect tire pressure and condition before each ride.
Check tire pressure before riding, when the tires are cold. This will provide the most accurate reading, as riding warms the tires and increases tire air pressure. Tires remain warm for at least 3 hours after a ride. Do not adjust tire pressure immediately after riding. As tires cool, the pressure will drop and result in underinflation. Always check and adjust tire pressure when tires are cold.
Using supplied air pressure gauge, adjust tire pressure to the recommended pressure. See Tire Pressure.

Tire Condition

Inspect the tire sidewalls, road contact surface and tread base. If inspection reveals cuts, punctures, cracks or other wear or damage, replace the tire before riding. Only use tires approved by Indian for the model of the motorcycle. See your dealer. Use of unapproved or an improperly mixed front and rear tire can result in decreased handling performance and stability, potentially leading to reduced control of the motorcycle.

Tire Tread Depth

Measure the tread depth near the center of the tread on both tires. See Tire Replacement. Replace any tire with a tread depth of less than 1/16 inch (1.6 mm).
