Reasons for Tire Pressure Warning Without Air Leakage?
2 Answers
When a car's tire pressure warning light comes on but the tires aren't low on air, it's usually due to excessive tire pressure. This is particularly common in summer when high ground temperatures combined with friction between the tires and road surface can cause tire pressure to rise, triggering the tire pressure monitoring system alarm. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and pulling, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends tire cords, reducing tire elasticity and increasing vehicle load during operation; Decreases puncture resistance. When encountering sharp objects like nails or glass, they can easily penetrate the tire, causing internal cracks or blowouts that may lead to tire bursts.
My car also experienced this situation before. The tires looked fine, but the tire pressure warning light was on, which really puzzled me. Later, I learned that it's mainly due to issues with the tire pressure monitoring system sensors, such as the battery running out after a few years of use or significant temperature changes. In cold weather, tire pressure naturally drops, making the system prone to false alarms; when temperatures rise and the tires recover, the warning might still be active without resetting. Sometimes, after changing wheels, if the system isn't properly calibrated, this can happen too. I recommend first checking the tire pressure yourself with a gauge to confirm there's no leak. If that's the case, it might be a sensor malfunction. Don't delay—get it checked at a repair shop as soon as possible to avoid potential issues. Safe driving is crucial, so it's best to address these minor problems early. Remember, regular tire pressure checks can prevent unexpected incidents.
