Temps are dropping, and most Maryland drivers know what it can do to a vehicle. You’re familiar with walking out to your Cadillac on a cold morning and seeing a warning light on the dashboard, and one of the more common ones is the TPMS light. Tire pressure drops alongside temperature, so understanding what's happening and what to do about it can help. For Hagerstown, Maryland drivers, it’s crucial to keep your vehicle running smoothly throughout the season. Why Cold Weather Affects Tire Pressure Air contracts when temperatures fall, and that means your tire pressure drops right along with it. Tires lose about 1lb. per sq. in. for every 10-degree drop in temperature. If overnight lows swing dramatically and boy, do they ever around here you might see a significant difference in your tire pressure from one morning to the next. Underinflated tires affect your Cadillac's handling, braking, and overall fuel efficiency. Whether you drive a Cadillac Escalade, LYRIQ, OPTIQ, or CT5, keeping your tires properly inflated during cold months is essential for both comfort and safety. The TPMS Light Most drivers first learn about a tire pressure issue when the Cadillac TPMS light illuminates on the instrument panel. TPMS stands for Tire Pressure Monitoring System, and it's simply designed to alert you when one or more tires drop below the recommended pressure threshold. Seeing the Cadillac TPMS light come on during cold weather doesn't necessarily mean you have a puncture or a damaged tire. In many cases, simply adding air to your tires will resolve the alert. However, if the light stays on after you've inflated your tires and driven a few miles, it's worth having the system inspected by a Certified service technician. How to Check and Correct Tire Pressure in Winter The recommended tire pressure for your Cadillac is listed in the owner's manual and on the sticker inside the driver's door jamb. Always check your tire pressure when the tires are cold - meaning the vehicle has been parked for at least 3 hours or driven fewer than a mile at low speed. Use a reliable tire pressure gauge and add air as needed. Do this regularly throughout the colder months, especially after a significant temperature swing. Staying proactive with Cadillac tire pressure cold weather checks helps you avoid unexpected handling issues and extends the life of your tires.
