Harley Davidson Softail Tire Pressure Sensor Reset

The tire pressure monitoring system (TPMS) is crucial for maintaining optimal tire pressure on your Harley Davidson Softail. If the TPMS light starts flashing, it indicates a problem that needs to be addressed. Resetting the tire pressure sensor can often resolve this issue, allowing you to ride safely and confidently.

Steps to Reset the Tire Pressure Sensor


  1. Check Tire Pressure: Ensure all tires are inflated to the recommended levels as per the tire pressure table.

  2. Turn on the Ignition: Insert the key and turn the ignition on without starting the engine.

  3. Locate the TPMS Reset Button: This is usually found under the dash or near the steering column.

  4. Press the Reset Button: Hold the button until the TPMS light blinks and then turns off.

  5. Start the Engine: Turn the key to start the engine and check if the TPMS light remains off.

Tire Pressure Monitoring System Light Flashing

If the TPMS light continues to flash after following the reset procedure, it may indicate a more serious issue. Below are some common causes:

Issue Description
Low Tire Pressure One or more tires may be under-inflated, requiring immediate attention.
Faulty Sensor The tire pressure sensor may be malfunctioning and needs replacement.
Battery Issues The battery in the tire sensor may be dead, requiring a new sensor installation.

Additional Tips


  • Regularly check tire pressure, especially before long rides.

  • Inspect tires for damage or wear that could affect pressure readings.

  • Consult your owner’s manual for specific instructions related to your model.

Importance of Maintaining Proper Tire Pressure

Maintaining proper tire pressure on your Harley Davidson Softail is crucial for several reasons. It directly impacts safety, performance, and fuel efficiency. Under-inflated tires can lead to poor handling, increased tire wear, and a higher risk of blowouts. Conversely, over-inflated tires can reduce traction and compromise ride comfort.

Safety Considerations

Proper tire pressure is essential for safe riding. When tires are inflated to the recommended levels, they provide optimal contact with the road, enhancing grip and stability. This is particularly important during cornering and braking, where improper tire pressure can lead to loss of control.

Performance and Handling

The performance of your Softail is significantly affected by tire pressure. Correctly inflated tires improve handling, allowing for smoother turns and better response to rider inputs. In contrast, incorrect tire pressure can result in sluggish handling and a less enjoyable riding experience.

Checking Tire Pressure

Regularly checking tire pressure is a simple yet vital maintenance task. Here’s how to do it:


  1. Gather Equipment: You will need a reliable tire pressure gauge, which can be digital or analog.

  2. Check When Cold: Measure tire pressure when the tires are cold, ideally before riding or after the bike has been parked for at least three hours.

  3. Remove Valve Stem Cap: Unscrew the cap from the tire valve stem.

  4. Press Gauge onto Valve: Firmly press the gauge onto the valve stem to get a reading. Ensure a good seal to avoid air loss.

  5. Read the Pressure: Check the reading on the gauge and compare it to the recommended pressure specified in your owner’s manual.

  6. Adjust as Necessary: If the pressure is too low, inflate the tire using an air compressor. If it’s too high, release some air until you reach the recommended level.

Useful Tips for Tire Maintenance


  • Check Tire Pressure Monthly: Make it a habit to check your tire pressure at least once a month.

  • Inspect Tires for Damage: Look for cuts, punctures, or uneven wear that could affect performance.

  • Use a Quality Gauge: Invest in a good tire pressure gauge for accurate readings.

  • Know the Recommended Pressure: Familiarize yourself with the recommended tire pressures for your specific Softail model.

  • Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes, so adjust accordingly when the seasons change.
