Harley-Davidson motorcycles are iconic machines known for their power, style, and performance. However, maintaining optimal performance requires attention to various factors, including tire pressure. Proper tire pressure is crucial for safety, handling, and fuel efficiency. Riders must understand the recommended tire pressures for their specific models to ensure a smooth and safe ride.
Correct tire pressure varies across different Harley-Davidson models and trims. Knowing the precise PSI (pounds per square inch) or BAR (barometric pressure) for your motorcycle can help prevent tire wear and enhance overall performance. Below is a detailed table outlining the recommended tire pressures for various Harley-Davidson motorcycle trims and engines.

Resetting Tire Pressure Sensor on Harley-Davidson Motorcycles
When the tire pressure monitoring system (TPMS) light on your Harley-Davidson motorcycle starts flashing, it indicates that there may be an issue with the tire pressure sensors or that the tire pressures are not within the recommended range. Resetting the tire pressure sensor is essential for accurate monitoring and safe riding. Here’s how to do it.
Steps to Reset Tire Pressure Sensor
- Ensure all tires are inflated to the recommended pressure as per the tire pressure table.
- Turn the ignition key to the “ON” position, but do not start the engine.
- Locate the TPMS reset button, typically found under the dashboard or near the steering column.
- Press and hold the TPMS reset button until the TPMS light blinks three times.
- Release the button and turn the ignition off.
- Start the engine and check if the TPMS light is off.
Tire Pressure Monitoring System Light Issues
If the TPMS light continues to flash after resetting, it may indicate a malfunction. Here are some common causes:
| Issue | Possible Cause | Solution |
|---|---|---|
| Flashing TPMS Light | Low tire pressure | Check and inflate tires to recommended PSI. |
| Flashing TPMS Light | Faulty sensor | Inspect and replace the sensor if needed. |
| Flashing TPMS Light | Battery issue | Check the battery of the TPMS sensor. |
| Flashing TPMS Light | Signal interference | Move away from potential sources of interference. |
Tips for Maintaining Tire Pressure Monitoring System
- Regularly check tire pressure at least once a month.
- Inspect the TPMS sensors during routine maintenance.
- Replace batteries in sensors as needed to avoid malfunctions.
- Use quality tires that are compatible with TPMS.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure on your Harley-Davidson motorcycle is crucial for several reasons. It affects not only your safety but also the overall performance and longevity of your tires. Under-inflated or over-inflated tires can lead to a range of issues, including poor handling, reduced fuel efficiency, and increased tire wear. Additionally, incorrect tire pressure can compromise your braking distance, making it essential to keep your tires properly inflated.
Benefits of Proper Tire Pressure
- Enhanced Safety: Proper tire pressure ensures better traction and stability on the road, reducing the risk of accidents.
- Improved Handling: Correctly inflated tires provide better steering response, enhancing your riding experience.
- Increased Fuel Efficiency: Maintaining the right pressure can improve your motorcycle’s fuel economy, saving you money in the long run.
- Extended Tire Life: Proper inflation reduces uneven wear, helping your tires last longer and perform better.
How to Check Tire Pressure
Checking your tire pressure is a straightforward process. Here’s how to do it effectively:
- Ensure your motorcycle has been parked for at least a couple of hours to allow the tires to cool down.
- Use a reliable tire pressure gauge. Remove the valve cap from the tire you want to check.
- Press the gauge onto the valve stem and read the pressure displayed on the gauge.
- Compare the reading to the recommended pressure found in your owner’s manual or on the tire pressure label.
- If the pressure is too low, add air until it reaches the recommended level. If it’s too high, release some air until the correct pressure is achieved.
- Replace the valve cap securely after checking and adjusting the pressure.
Useful Tips for Maintaining Tire Pressure
- Check tire pressure at least once a month, and before long rides.
- Use a high-quality tire pressure gauge for accurate readings.
- Inspect tires for visible damage or wear regularly.
- Consider investing in a tire pressure monitoring system (TPMS) for real-time monitoring.
- Always refer to your motorcycle’s manual for the specific tire pressure recommendations based on load and riding conditions.
