Why is my low tire pressure light on but my tires are fine?
If your vehicle's low tire pressure warning light is illuminated, it may seem concerning, especially if your tires appear to be properly inflated. However, there are a few common reasons why this light can turn on even when your tires are in good condition.
Reasons for the Low Tire Pressure Light
- Temperature Changes - Tire pressure can fluctuate with changes in temperature. As the weather gets colder, the air in your tires contracts, causing the pressure to drop and triggering the warning light.
- Slow Air Leaks - Even a small leak in your tire can cause the pressure to gradually decrease over time, eventually setting off the low pressure alert.
- Incorrect Tire Pressure - If you've recently filled your tires but didn't add the recommended amount of air, the pressure may still be too low, causing the light to turn on.li>
- Faulty Tire Pressure Monitoring System - In some cases, the tire pressure monitoring system (TPMS) itself may be malfunctioning, triggering the warning light even when tire pressure is normal.li>
If the low tire pressure light comes on and your tires appear properly inflated, it's a good idea to check the recommended pressure levels for your vehicle and adjust the air as needed. You should also inspect your tires for any slow leaks. If the light persists, it may be a sign of a more serious issue with your TPMS that requires professional diagnosis and repair.
