As temperatures drop, you might notice an unwelcome guest lighting up your dashboard: the Tire Pressure Monitoring System (TPMS) light. This common occurrence during colder months can be frustrating but understanding why it happens and how to handle it is crucial for your safety and your vehicle’s performance.
Why Does the TPMS Light Come On in Cold Weather?
When the temperature drops, the air inside your tires contracts, causing a decrease in tire pressure. For every 10°F drop in temperature, tire pressure can decrease by about 1 PSI (pounds per square inch). If the pressure falls below the manufacturer’s recommended level, the TPMS light will trigger, alerting you to check your tires.
Where to Find the Correct Tire Pressure for Your Vehicle
Maintaining the correct tire pressure is essential, especially in colder weather, to ensure safety, fuel efficiency, and optimal tire lifespan. Here’s where to find the recommended tire pressure for your vehicle:
Driver’s Side Door Jamb: Open the driver’s door and look for a sticker on the inside of the door frame. This label lists the manufacturer’s recommended tire pressure for both front and rear tires.
Owner’s Manual: Your vehicle’s owner’s manual will also provide detailed information on the correct tire pressure.
Tire Itself: While the maximum pressure is listed on the tire sidewall, this is not the recommended running pressure. Always refer to the vehicle-specific recommendations.
Why Maintaining Proper Tire Pressure Matters in Cold Weather
Safety: Underinflated tires can lead to poor handling, longer stopping distances, and a higher risk of blowouts. Properly inflated tires maintain better contact with the road, providing improved traction on icy or wet surfaces.
Fuel Efficiency: Low tire pressure increases rolling resistance, causing your engine to work harder and decreasing fuel efficiency. Keeping your tires properly inflated can save you money at the pump.
Tire Longevity: Driving with incorrect tire pressure can cause uneven tire wear, leading to premature tire replacement. Keeping the correct pressure ensures even wear and extends the life of your tires.
TPMS Accuracy: Properly inflated tires prevent the TPMS light from giving false warnings, allowing you to focus on real issues.
What to Do When Your TPMS Light Comes On
Check Tire Pressure: Use a reliable tire pressure gauge to check each tire. If the pressure is low, inflate the tires to the recommended PSI.
Temperature Adjustments: Tire pressure can fluctuate as temperatures change throughout the day. If the light turns off after a few miles of driving, it’s likely due to the warming of the tires.
Get a Professional Inspection: If the light stays on or you notice a significant pressure drop, it’s best to visit a trusted mechanic for a thorough inspection. Cold weather can also reveal small leaks or punctures.
