Now that it is turning colder, you may notice lots of changes around you; leaves falling, and maybe even snow falling! Your tire's air pressure could be falling too. As the weather turns colder, you may notice your tire air pressure light coming on often. This is something you need to determine is a service issue or you just to top your tires off with a little air.
Winter's cold temperatures can affect many parts and processes in your vehicle. It will cause tire pressure to drop about 1 psi for every 10°F drop in air temperature. Getting a tire pressure warning light on a frosty morning doesn't necessarily indicate a puncture, just that your tires are running low pressure and you need to top them off as soon as possible.
When you are continually adding air to one or more of your tires, you could have an issue with the tire(s). It is more than likely your tire's valve system. This is the mechanism that sticks out of your tire to allow you to add air. It could be corroded, broken, or porous and will need to be serviced. Air loss can also be from the rim of the tire at its wheelbase. Here, air can escape, causing a slow leak.
If you are constantly needing to add air to your tires, your best bet is to see a mechanic who can quickly fix the air issue and keep you safe on your tires. Stay safe out there! Contact me if you are in need of a new vehicle!
