What is a Tire Pressure Monitoring System?
Are you tired of constantly worrying about the health of your BMW X4’s tires? Fear not because BMW has equipped their X4 models with a cutting-edge technology called a TPMS (Tire Pressure Monitoring System). The system constantly monitors the air pressure of each tire and alerts the driver when a tire’s pressure falls below a certain level. Want to know more about this innovative feature? Keep reading to find out how TPMS works, when to reset it and common causes for the tire warning light to turn on.

How Does the BMW X4 TPMS Work?
The BMW X4’s TPMS consists of sensors mounted inside each wheel that continuously measure the air pressure of each tire.
These sensors send data wirelessly to the car’s onboard computer, which calculates the pressure of each tire and compares it to the recommended level.
If the pressure of any tire falls below a certain threshold (usually 10-25% below the recommended level), the TPMS will illuminate a warning light on the dashboard and make an audible sound.
The BMW X4’s TPMS will display a message on the dashboard indicating which tire is underinflated, allowing the driver to take appropriate action.
The TPMS can also be manually reset by the driver once the tire pressure has been adjusted. (follow steps above)
In the newer BMW X4 models (G02), the TPMS can also measure the temperature of each tire to provide more accurate readings and improve performance.
When to Reset BMW X4 TPMS?
When adjusting tire pressure
Following tire rotation, balancing, or wheel alignment procedures
After replacing one or more tires
When installing new rims or wheels (remember to transfer old sensors to new wheels)
If the TPMS warning light remains illuminated after inflating a tire to the correct pressure
When swapping seasonal tires (e.g., switching between winter and summer tires)
Following any tire or wheel-related service or repair
After replacing the vehicle’s battery
Following a jump-start of a dead battery
If a TPMS sensor is repaired or replaced.
What are Common Causes for Tire Pressure Lights to Turn On?
Low tire pressure in one or more tires
A flat tire or slow leak due to puncture or damage to the tire
A crack in one or more rims or wheels. (This is extremely common in all BMW vehicles)
Significant changes in ambient temperature greatly affects tire pressure and is the number one cause of setting off TPMS warning lights!
Dead or dying tire pressure sensor battery (to figure out which sensor is dead or dying you need to use a TPMS tool)
Vehicle weight overload. To much weight in on or being towed by the vehicle
Malfunctioning, leaking or damaged TPMS sensors
TPMS software or calibration issues (some systems may need to be updated)
A dead vehicle battery then jumped can cause the TPMS light to come on
What Happens When Your BMW X4 Tires are Underinflated?
Proper tire inflation is crucial for optimal performance of your BMW X4. When tires are underinflated it can result in reduced fuel efficiency, uneven tire tread wear, and compromised handling and braking abilities. These issues can increase the chance of accidents and negatively impact your driving experience with your BMW X4. To ensure your vehicle is performing at its best, it’s essential to maintain appropriate tire pressure. We recommend checking tire pressure monthly and before long trips! (At the least!)
