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) |
|---|---|---|---|---|
| i3 (60 Ah) | 38 | 2.62 | 38 | 2.62 |
| i3 (94 Ah) | 38 | 2.62 | 38 | 2.62 |
| i3s (94 Ah) | 36 | 2.48 | 36 | 2.48 |
Resetting Tire Pressure Sensor for 2018 BMW i3
The tire pressure monitoring system (TPMS) in the 2018 BMW i3 is designed to alert you when tire pressures are outside the recommended range. If the TPMS light is flashing, it indicates a problem that needs attention. Resetting the tire pressure sensor is crucial for ensuring accurate readings and maintaining optimal vehicle performance.
Tire Pressure Monitoring System Light Flashing
If the TPMS light is flashing, follow these steps to diagnose and reset the system:
- Check the tire pressures for all four tires.
- Inflate any under-inflated tires to the recommended PSI.
- Inspect the tires for any visible damage or punctures.
- Turn on the ignition without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering wheel.
- Press and hold the reset button until the TPMS light blinks three times.
- Start the engine and drive for a few minutes to allow the system to recalibrate.

| Step | Description |
|---|---|
| 1 | Check tire pressures using a reliable gauge. |
| 2 | Inflate or deflate tires as needed. |
| 3 | Inspect for damage or leaks. |
| 4 | Locate and press the TPMS reset button. |
| 5 | Start the engine and drive to complete the reset. |
By following these steps, you can effectively reset the tire pressure sensor in your 2018 BMW i3. Regular maintenance and monitoring of tire pressure will help ensure a safe and efficient driving experience.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the performance, safety, and efficiency of your 2018 BMW i3. Incorrect tire pressure can lead to various issues, including reduced fuel efficiency, uneven tire wear, and compromised handling. Additionally, under-inflated tires can overheat, increasing the risk of blowouts. Conversely, over-inflated tires can lead to a harsher ride and decreased traction, especially in wet conditions.
Benefits of Proper Tire Pressure
- Improved Fuel Efficiency: Correct tire pressure ensures optimal contact with the road, reducing rolling resistance and improving energy consumption.
- Enhanced Safety: Properly inflated tires provide better handling and braking performance, reducing the likelihood of accidents.
- Longer Tire Life: Maintaining the right pressure prevents uneven wear, extending the life of your tires and saving you money in the long run.
- Better Ride Comfort: Properly inflated tires contribute to a smoother ride, enhancing overall driving comfort.
How to Check Tire Pressure
Regularly checking your tire pressure is essential. Here’s how to do it effectively:
- Gather Tools: You will need a reliable tire pressure gauge and an air compressor if adjustments are necessary.
- Check When Cold: Measure tire pressure when the tires are cold, ideally before driving or after the vehicle has been parked for a few hours.
- Remove Valve Caps: Unscrew the valve caps from each tire and keep them in a safe place.
- Use the Gauge: Press the tire pressure gauge onto the valve stem firmly. The gauge will provide a reading of the current tire pressure.
- Compare with Recommended Pressure: Refer to the owner’s manual or the tire placard located on the driver’s side door jamb for the correct PSI.
- Adjust as Needed: Inflate or deflate the tires to reach the recommended pressure, then replace the valve caps.
Useful Tips for Tire Maintenance
To ensure your tires remain in optimal condition, consider the following tips:
- Check Monthly: Make it a habit to check your tire pressure at least once a month, as tires can lose air over time.
- Inspect for Damage: Regularly look for any signs of wear, such as cracks, bulges, or foreign objects embedded in the tires.
- Rotate Tires: Rotate your tires every 5,000 to 7,500 miles to promote even wear.
- Alignment and Balancing: Ensure your wheels are properly aligned and balanced to prevent uneven tire wear.
By prioritizing tire maintenance and regularly checking tire pressure, you can enhance the safety, efficiency, and longevity of your 2018 BMW i3.
