What Causes Abnormal Tire Pressure on the Dashboard?

[DelNadia]

Abnormal tire pressure on the dashboard is caused by either overinflation or underinflation, requiring you to stop and check the tire pressure. Indirect tire pressure monitoring systems determine tire pressure by comparing the rotational speeds of the four wheels. However, this method has some limitations—it cannot specifically indicate which tire has insufficient pressure and may produce false alarms under certain conditions. Therefore, any factor that causes inconsistent wheel speeds can trigger a tire pressure warning. For example, after replacing a single tire, the new tire may have a slightly different diameter from the old ones, causing the new wheel to rotate at a different speed. If the speed difference reaches a certain threshold, the tire pressure monitoring system will illuminate the warning light. Similarly, when driving on sand or icy roads, if a wheel slips and spins excessively, the system may interpret this as abnormal tire pressure and trigger an alarm.

The other day when I was driving to work, a tire pressure warning suddenly lit up on my dashboard, which really gave me a scare. This kind of thing usually means a tire is leaking—maybe it got punctured by a nail on the road, or the pressure dropped due to colder weather. After pulling over to check, I actually found a small nail in the tire. Luckily, I caught it early; otherwise, driving on the highway could have led to a blowout, which is extremely dangerous. Now, I always keep a small tire pressure gauge in my car and check the pressure regularly to maintain it at the manufacturer's recommended level (usually marked on the door frame). If the warning light stays on, it might be a sensor issue, and sometimes resetting it does the trick. In short, don't ignore it—address it promptly to avoid bigger problems.

Don't panic when the tire pressure warning light comes on. As a car enthusiast, I've encountered this several times. Main causes include tire leaks, overinflation, or underinflation—especially during cold winter starts. It could also be a sensor false alarm, particularly after wheel or rim modifications when positioning is inaccurate. I always carry a portable tire pressure gauge to check all tires and pinpoint the issue. Additionally, temperature changes cause pressure fluctuations; driving a few kilometers sometimes resolves it. Regularly inspect tires for punctures or sidewall damage—neglecting this increases fuel consumption and shortens tire lifespan, which isn't worth it. For repeated false alarms, visit a shop to check sensor batteries or recalibrate.

For the safety of my family, I must pay attention to the tire pressure warning light. Last time when I picked up my child from school, the light came on, possibly due to a small puncture causing a slow leak or the drop in tire pressure from colder weather. After parking, I carefully inspected each tire and found one with a slow leak, so I quickly added some air and drove home. Later, I took it to the repair shop for a patch, which didn't cost much. I remind everyone to always keep a tire pressure gauge handy, and use the spare tire tools if available. Driving with the warning light on is risky, as it can lead to skidding during turns and affect braking distance. Make it a habit to check tire pressure monthly, especially during autumn and winter seasons.
