How to Adjust Tire Pressure on BMW 740e xDrive Long?

Proper tire pressure is essential for ensuring optimal performance, safety, and fuel efficiency of your BMW 740e xDrive Long. Regularly checking and adjusting tire pressure is a simple maintenance task that can significantly improve your driving experience. In this article, we will guide you through the step-by-step process of adjusting tire pressure on your BMW 740e xDrive Long.

Materials Needed:

• Tire pressure gauge
• Air compressor or tire inflator

Step 1: Gather the Necessary Information

Before adjusting the tire pressure, you must know the recommended tire pressure for your BMW 740e xDrive Long. This information is usually indicated in the vehicle owner's manual or on a sticker inside the driver's door jamb. Note down the recommended pressure for both the front and rear tires.

Step 2: Check Current Tire Pressure

Park your BMW 740e xDrive Long on a level surface and engage the parking brake. Unscrew the valve cap from the first tire you want to check. Attach the tire pressure gauge firmly onto the valve stem and press down to get an accurate reading. Repeat this process for all four tires, noting down the pressure of each tire.

Step 3: Adjust Tire Pressure

If the current tire pressure is lower than the recommended pressure, you need to add air. If it's higher, you should release some air until reaching the desired level.

1. Adding Air: Connect the air compressor or tire inflator to a power source. Remove the valve cap from the tire and securely attach the air hose onto the valve stem. Activate the air compressor and add air in short bursts, periodically checking the pressure with the tire gauge. Inflate the tire gradually and avoid overfilling. Once the pressure reaches the recommended level, remove the compressor hose and replace the valve cap.
2. Releasing Air: If the tire pressure is higher than recommended, you can release air by pressing the valve stem core using a suitable tool like a tire pressure gauge or a dedicated valve core remover. Slightly press the valve down until you hear the sound of air escaping. Monitor the pressure using the tire gauge and release air slowly until you reach the desired level. Once done, replace the valve cap.

Step 4: Verify the Adjusted Tire Pressure

After adjusting the tire pressure of all four tires, it's essential to double-check the readings to ensure they align with the recommended values. Reattach the pressure gauge to each tire and verify that the pressure matches the specifications provided by BMW.

Step 5: Maintain Balanced Tire Pressure

Regularly monitoring and adjusting tire pressure is crucial to maintain balanced and even wear on your BMW 740e xDrive Long's tires. Remember to repeat this process at least once a month or whenever there are significant fluctuations in temperature or when you notice uneven tire wear.

By following these steps, you can easily adjust the tire pressure on your BMW 740e xDrive Long, promoting better driving dynamics, improved fuel efficiency, and increased safety on the roads. Properly inflated tires not only ensure better vehicle performance but also extend the life of your tires, ultimately saving you money in the long run.
