Tire Pressure Table for Different Trim/Engine
| Trim/Engine | Front Tire Pressure (PSI) | Front Tire Pressure (BAR) | Rear Tire Pressure (PSI) | Rear Tire Pressure (BAR) |
|---|---|---|---|---|
| BMW i3s (Standard) | 38 | 2.62 | 38 | 2.62 |
| BMW i3s (Range Extender) | 36 | 2.48 | 36 | 2.48 |
| BMW i3s (Sport) | 40 | 2.76 | 40 | 2.76 |
| BMW i3s (City) | 34 | 2.34 | 34 | 2.34 |
BMW i3s Tire Pressure Sensor Reset
The tire pressure monitoring system (TPMS) in the BMW i3s is designed to alert drivers when tire pressure is low or when there’s a malfunction. If the TPMS light is flashing, it indicates a problem that requires immediate attention. Resetting the tire pressure sensor is an essential step to ensure that the system functions correctly and provides accurate readings.
Steps to Reset the Tire Pressure Sensor
- Ensure all tires are inflated to the recommended pressure as specified in the owner’s manual.
- Turn on the ignition without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering wheel or in the glove compartment.
- Press and hold the TPMS reset button until the TPMS light blinks three times, then release the button.
- Start the engine and allow the vehicle to run for about 20 minutes to complete the reset process.
- Check if the TPMS light has turned off. If it remains on, repeat the process or consult a professional.
Tire Pressure Monitoring System Light Flashing
If the TPMS light is flashing, it typically means there’s a malfunction in the system. This could be due to a faulty sensor, a dead battery in the sensor, or a communication error. Ignoring a flashing light can lead to unsafe driving conditions.
Common Causes for Flashing TPMS Light
| Issue | Description |
|---|---|
| Low Tire Pressure | One or more tires are below the recommended pressure. |
| Faulty Sensor | A tire pressure sensor may be malfunctioning or damaged. |
| Battery Failure | The battery in the tire pressure sensor may be dead. |
| Communication Error | There may be a failure in communication between the TPMS and the vehicle’s computer. |
When to Seek Professional Help
If the TPMS light continues to flash after resetting or if you suspect a malfunction, it’s advisable to seek professional assistance. A qualified technician can diagnose the issue and recommend appropriate solutions. Ignoring the problem can lead to unsafe driving conditions and potential tire damage.
Importance of Maintaining Proper Tire Pressure
Maintaining the correct tire pressure is crucial for the safety and performance of your BMW i3s. Properly inflated tires ensure optimal handling, fuel efficiency, and overall vehicle longevity. Under-inflated tires can lead to increased rolling resistance, which can negatively impact your electric vehicle’s range. Conversely, over-inflated tires may cause a harsh ride and reduce traction, increasing the risk of blowouts.
Benefits of Proper Tire Pressure
- Improved Fuel Efficiency: Correct tire pressure minimizes energy consumption, extending the driving range of your electric vehicle.
- Enhanced Safety: Properly inflated tires provide better traction and handling, reducing the likelihood of accidents.
- Longer Tire Life: Maintaining the right pressure prevents uneven wear, extending the lifespan of your tires.
- Better Ride Comfort: Correct pressure levels contribute to a smoother driving experience.
How to Check Tire Pressure
Regularly checking tire pressure is essential for maintaining optimal performance. Here’s how to do it effectively:
Steps to Check Tire Pressure
- Purchase a reliable tire pressure gauge if you don’t already have one.
- Wait until the tires are cold, preferably in the morning, as heat from driving can increase pressure readings.
- Remove the valve cap from the tire you wish to check.
- Press the tire pressure gauge onto the valve stem firmly to get an accurate reading.
- Note the pressure reading in PSI or BAR.
- Compare the reading to the recommended tire pressure listed in your owner’s manual or on the sticker inside the driver’s door.
- If the pressure is too low or too high, adjust accordingly.
Useful Tips for Tire Pressure Maintenance
- Check tire pressure at least once a month and before long trips.
- Always check the pressure when the tires are cold for the most accurate reading.
- Keep a portable air compressor in your vehicle for quick adjustments on the go.
- Inspect tires regularly for signs of wear or damage, which can also affect pressure.
- Rotate tires as recommended to ensure even wear and maintain consistent pressure across all tires.
By prioritizing proper tire pressure, you enhance the safety, efficiency, and performance of your BMW i3s. Regular checks and maintenance can save you money in the long run and contribute to a more enjoyable driving experience.
