Be sure tires are properly inflated, balanced, undamaged, and have adequate tread. Inspect your tires regularly and see a Harley-Davidson dealer for replacements. Riding with excessively worn, unbalanced, improperly inflated, overloaded or damaged tires can lead to tire failure and adversely affect stability and handling, which could result in death or serious injury.

Do not use liquid tire balancers or sealants in aluminum wheels. Using liquid tire balancers or sealants can cause rapid corrosion of the rim surface, which could cause tire deflation. Tire deflation can cause loss of vehicle control, which could result in death or serious injury. (00631b)
The motorcycle has a tire pressure monitoring system (TPMS). Sensors at the valve stem measure pressure and periodically signal pressure data to the motorcycle. TPMS requires no maintenance other than the changing of sensors when the sensor battery is low. See a Harley-Davidson dealer for service if there is a TPMS malfunction or low battery indication for the TPMS sensors.
After tire replacement, check the status of the TPMS system. Check the low tire pressure/TPMS malfunction indicator, odometer TPMS data, radio TPMS data, and the actual tire pressure with a tire gauge to make sure the system is functioning properly.
Do not use liquid tire balancers or sealing agents in wheels with a TPMS sensor. Damage to the sensor can result.
TPMS sensors are specifically designed for use with the wheels and tires specified for the motorcycle. Attempting to use sensors on other wheels can result in lack of proper fitment, TPMS malfunction and air leakage.
Tire Inflation
Inflate the tires according to specifications in Specifications → Specifications → Specified Tires and as specified on the label on the frame downtube.
Specifications → Specifications → Specified Tires indicates the specified pressure for tires when they are cold (vehicle parked for at least three hours at ambient temperature of 20 °C (68 °F)). Tire pressure will increase as the tires get warm.
Do not use the TPMS system as a pressure gauge when adding or removing air from a tire. Sensor data is sent to the TPMS at varying intervals (depending on whether the vehicle is in motion, parked on the jiffy stand, or has a significant change in tire pressure). The tire pressure data may not refresh immediately when adding or removing air from the tire. Over-inflation or under-inflation can result.
Do not rotate valve stems from their properly installed position. This can affect the valve stem seal and result in a slow leak.
