Why Does My Car Display a Check Tire Pressure Warning?
Your car displays a “Check Tire Pressure” warning when one or more tires have a pressure level below or above the recommended range. This warning is part of the Tire Pressure Monitoring System (TPMS), which alerts drivers to potential tire issues that can affect safety and fuel efficiency.
According to the National Highway Traffic Safety Administration (NHTSA), TPMS is a safety feature designed to monitor tire pressure and alert drivers when tire inflation falls below a certain threshold. Proper tire pressure is crucial for optimal vehicle performance and safety.
The underlying causes for a “Check Tire Pressure” warning can vary. Common reasons include:
- Under-inflation: Tires may lose air over time due to natural seepage or punctures.
- Over-inflation: Tires may be overfilled, especially after changes in temperature or incorrect adjustments.
- Temperature Changes: Tire pressure typically decreases in colder weather and increases in warmer weather.
- Faulty Sensors: Sometimes, the TPMS sensors may malfunction or become damaged.
In tire terminology, “tire pressure” refers to the amount of air within the tire, measured in pounds per square inch (PSI). A well-inflated tire ensures proper contact with the road, optimal handling, and better fuel efficiency. Conversely, under-inflated tires can lead to increased wear and potential blowouts, while over-inflated tires can reduce traction.
Mechanically, tire pressure affects the contact patch, which is the area of the tire in contact with the road. A proper contact patch ensures effective braking and stability. When pressure is too low, the tire flexes more and generates extra heat, which can lead to failures. High pressure, on the other hand, can result in a stiff ride and increased stress on the tire sidewalls.
Specific conditions or actions contributing to tire pressure issues include:
- Seasonal Changes: Sudden drops in temperature can decrease tire pressure by approximately 1 PSI for every 10-degree Fahrenheit drop.
- Long Periods of Non-Use: Tires can lose pressure while sitting idle.
