The BMW M240i is a high-performance vehicle that demands attention to detail, especially when it comes to tire maintenance. Proper tire pressure is crucial for optimal handling, safety, and fuel efficiency. Each trim and engine variant may have specific tire pressure requirements, making it essential for owners to know the correct specifications.
Maintaining the right tire pressure not only enhances driving performance but also prolongs tire life. Under-inflated or over-inflated tires can lead to poor traction, uneven wear, and increased risk of blowouts. Understanding the recommended tire pressures for different M240i trims ensures that drivers can enjoy the full capabilities of their vehicle.

BMW M240i Tire Pressure Sensor Reset
The tire pressure monitoring system (TPMS) is an essential feature in the BMW M240i that alerts drivers when tire pressure is too low or too high. If the TPMS light is flashing, it indicates a malfunction or that the system requires resetting. Knowing how to reset the tire pressure sensor can help you maintain optimal tire performance and safety.
Steps to Reset the Tire Pressure Sensor
- Ensure all tires are inflated to the recommended pressure.
- 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 it.
- Start the engine and drive for about 10 minutes to allow the system to recalibrate.
Common Reasons for TPMS Light Flashing
- Low tire pressure in one or more tires.
- Faulty tire pressure sensor.
- Temperature changes affecting tire pressure.
- Improperly mounted or damaged tires.
Tire Pressure Monitoring System Light Status
| Light Status | Description |
|---|---|
| Solid Light | Tire pressure is low in one or more tires. Check and inflate as necessary. |
| Flashing Light | TPMS malfunction. Reset the system or check for sensor issues. |
| No Light | All tires are properly inflated, and the TPMS is functioning correctly. |
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the performance and safety of your BMW M240i. Under-inflated or over-inflated tires can lead to various issues, including reduced handling, increased tire wear, and compromised safety. Proper tire pressure ensures optimal contact with the road, enhancing traction and stability. This is especially important for a performance vehicle like the M240i, where handling dynamics play a significant role in the driving experience.
Additionally, correct tire pressure contributes to fuel efficiency. Tires that are not inflated to the recommended levels can increase rolling resistance, leading to higher fuel consumption. Regularly checking and maintaining tire pressure can save you money at the pump while ensuring a smoother ride.
How to Check Tire Pressure
Checking tire pressure is a straightforward process that can be done at home or at a service station. Follow these steps for accurate results:
- Purchase a reliable tire pressure gauge. Digital gauges are often easier to read than analog ones.
- Ensure tires are cold, as heat from driving can give inaccurate readings.
- Remove the valve cap from the tire you wish to check.
- Press the tire pressure gauge onto the valve stem firmly to get a reading.
- Note the pressure displayed on the gauge and compare it to the recommended pressure listed in your owner’s manual or on the driver’s side door jamb.
- If the pressure is low, inflate the tire to the recommended level. If it’s too high, release some air until it reaches the correct pressure.
Useful Tips for Maintaining Tire Pressure
- Check tire pressure at least once a month, and before long trips.
- Inspect tires for signs of damage or wear, as these can affect pressure retention.
- Use a tire pressure monitoring system (TPMS) if available, but don’t rely solely on it; manual checks are still important.
- Be aware of seasonal changes; temperature fluctuations can affect tire pressure significantly.
- Rotate tires regularly to ensure even wear and maintain optimal performance.
By following these guidelines, you can ensure that your BMW M240i remains in peak condition, providing you with the performance and safety you expect from this high-performance vehicle.
