Why does the tire pressure alarm go off in summer but the tires are fine?

In summer, the tire pressure alarm goes off but the tires are fine due to abnormal tire pressure, unreset tire pressure monitoring, or damaged tire pressure sensors. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The alarm usually triggers when pressure is below 1.8 bar or exceeds 3.0 bar. In this case, tire inspection and pressure adjustment are required. Unreset tire pressure monitoring: After inflating the tires, if the tire pressure monitoring system isn't reset in time, it continues to record the previous data, causing the tire pressure warning light to illuminate. Simply performing a tire pressure reset will resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged by impact while driving, it can also trigger the tire pressure warning light. For sensor damage issues, the only solution is to replace it with a new component.

As a seasoned driver with over a decade of experience, I often encounter tire pressure warnings in summer when the tires appear perfectly fine. This is mostly because high temperatures cause the air inside the tires to expand, naturally increasing the tire pressure, which triggers the alarm when it exceeds the system's preset value. While it's good that the tires themselves are fine, you shouldn't take it lightly. Last time I encountered an alarm on the highway, it scared me into pulling over immediately to check. Using a portable tire pressure gauge, I confirmed it was indeed due to elevated pressure from the heat. Once the car cooled down, the tire pressure returned to normal. I recommend paying attention to weather forecasts and topping up the tires to the standard pressure when the car is cold before heading out on hot days to avoid false alarms. Additionally, tire pressure monitoring sensors may become less sensitive over time, so I make it a habit to get a system check at the repair shop regularly to avoid any mishaps. Safe driving is no small matter—developing good habits is crucial.

If the tire pressure warning light comes on in summer but the tires appear intact, I believe safety should be the top priority. Hot weather causes air to expand and pressure to rise, making the system alert a normal occurrence. Just because the tire surface looks fine doesn't mean there's no internal issue. Overinflation increases the risk of a blowout, especially at high speeds. I recommend pulling over immediately and using a tire pressure gauge to check the actual pressure. If it's too high, release some air. Regular tire maintenance is also crucial, such as cleaning the rims to prevent dust from affecting the sensors. Never ignore the warning—preventing an accident is better than regretting one later.

I haven't been driving for many years, but I'm well aware that tire pressure warnings are common in summer. High temperatures can cause tire pressure to rise, easily triggering the warning, even when the tires themselves are undamaged. The solution is quite simple. I usually wait for the car to cool down and then recheck the tire pressure, or go directly to a professional shop to see if the system settings are appropriate, avoiding making a mountain out of a molehill.
