What is the reason why BMW tires cannot be recognized?

BMW tires may not be recognized due to tire replacement. Simply have the repair shop use a computer to match them. Tire replacement indicators: There is usually a triangular mark on the sidewall of the tire. Following the direction indicated by the triangular mark on the sidewall, you can find small blocks on the tread indicating the wear limit. According to current regulations in China, tires should be replaced when the surface tread wears below 1.6 mm. The wear indicators on the tires are also set according to this standard. BMW markings: A set of numbers and letters is used to indicate the manufacturing date and quantity of the tire. For example, "98N08B5820" indicates the 5820th tire produced in Group B in August 1998. The production batch number is used to identify the age and storage time of the tire.
My older BMW model sometimes shows errors in tire pressure monitoring and fails to identify specific tire pressure data, which is quite common. The reason is mostly that the battery in the tire pressure sensor is depleted. These small batteries inside the sensors typically last five to seven years and naturally degrade over time. Additionally, if you've recently replaced a tire or had a tire repaired, the sensor might not have synced with the car's onboard computer, causing the system to not recognize its position. In cold winter weather, the signal can also weaken, but it usually recovers after driving for a while. My suggestion is to try a DIY fix first: check the car's menu for a reset option or drive slowly for a few kilometers to let it auto-calibrate. If that doesn't work, take it to a 4S shop or auto repair shop to scan for error codes immediately. Don't delay—if the tire isn't recognized properly, the tire pressure won't be accurately measured, and low pressure could lead to a dangerous blowout. Regular maintenance, like manually checking tire pressure periodically, can prevent issues and make driving safer.
I've been driving a BMW X5 for several years, and last month the tire pressure monitoring suddenly stopped displaying, which gave me a scare. After checking around, I found it's mainly a sensor issue: either the internal coil of the sensor is corroded, causing poor contact and preventing signal transmission, or the sensor position wasn't registered in the system after changing new tires. It could also be due to wheel rim deformation or unbalanced tire installation, causing the sensor to wobble and misread signals. The solution is simple to try: find the tire settings in the steering wheel menu, click the learning option to let it recognize again. If that doesn't work, take a highway drive to see if it self-heals. I remember once after a rainy day, it suddenly stopped working, but after drying the wheels, it returned to normal. Cost-wise, each sensor is about 200 yuan, and you can replace it yourself if you have some DIY knowledge. The key is not to ignore it, as the risk of tire pressure loss is significant, and early handling is safer and saves money. Develop a habit of manually checking tire pressure every month to extend the system's lifespan.
As an auto mechanic, I've dealt with numerous cases of BMW tire pressure monitoring system (TPMS) failures. There are three common causes: dead sensor batteries or internal circuit malfunctions; system software requiring updates or improper reset procedures; and tire position deviations or wheel imbalance errors affecting signal reception. For diagnosis, first use a professional scanner to read fault codes and identify the problematic tire. If the sensor is confirmed defective, replace it with a new unit and perform programming synchronization. Preventatively, avoid driving through puddles and rough roads to minimize impact damage. Cost-wise, aftermarket sensors can be replaced for around a hundred dollars, but ensure proper flush mounting. Owners can perform self-checks: observe the dashboard warning light after starting the vehicle - if it stays illuminated, prompt repair is needed. Safety comes first, as inaccurate tire pressure readings can lead to blowout accidents.
