Tire Pressure in Falling Temperatures

Tire Pressure in Falling Temperatures

Fall is here and falling temperatures are on the way.   As Fall progresses towards winter, the temperatures will be dropping. As this happens, the pressure in your tires will fall as well.  For every 10 degree drop in temperature, your tires will lose 1-2 psi (pound per square inch).  This means if the temperature falls from 70 degrees to 20 degrees, your tires will lose 5 to 10psi. If your tires lose 10psi, your car's tire pressure monitor light will come on (if equipped) and your tires may look visibly low.  If you are filling your tires up, take note of all the starting pressures.  If one tire is much lower than the others, you may have a leak.  If they are all about the same, fill them back to operating psi. I know, your next question is, "What is the operating psi of my tires?"  To find the operating psi of your tires, open the driver door and look for a placard in the door panel.  It will have ... read more



Nitrogen Versus Compressed Air In Your Tires

Nitrogen is Earth’s most abundant gas. In place of compressed air, can it benefit your tires to help them perform better, last longer, or increase fuel mileage? Air is comprised of approximately 78 percent nitrogen, 21 percent oxygen, and 1 percent of 13 other gases. It also contains, on average, 1-3 percent of water vapor. So is it worth eliminating the 22 percent of the other gases? My research revealed the nitrogen molecule has a more difficult time migrating through the rubber compound than air does. The other benefit is that nitrogen pressure does not fluctuate as much as regular compressed air with temperature changes. This is good because tire pressure can change as much as 1 psi for every 10 degrees in temperature variation with compressed air. The biggest benefit is that through the course of removing the other air molecules, it also removes most of the water vapor. This is key, as water vapor in your tire can cause more of a pressure swing than dry air and promote mor ... read more
