There are a few reasons your car tire loses air. Keep in mind that any tire loses air slowly (about one to three psi a month) due to osmosis. It is the bigger leaks that you need to be concerned about. If the air in your tire is deflated more than twenty five percent from the recommended pressure, you are putting yourself at risk to get into a tire-related vehicle crash. It is very important you look at the pressure of your tires on a pretty consistent basis.
A poor valve stem or bent/damaged wheel can cause your tire to lose air. In regards to the valve stem, chemicals on the road and air can cause this to happen. Rust and hitting things in the road can bend your wheel. Both of these issues can cause the tire air to get out quicker.
Damage to the tire (nails, road hazards, or bead damage) can also cause the rate at which the air from your tire leaks to be more than two to three psi’s a day! When you notice the air in your tires decreasing (especially if it’s in a quick manner) you need to bring your car to the mechanical as soon as possible!
Fluctuations in the weather temperature (dropping by ten degrees Fahrenheit or increasing by ten degrees Fahrenheit) will cause your tire to either lose or gain about two percent of air.
Again, it is very important to keep your eyes on the pressure of your tires. It helps keep you and your family safe. If you are unable to fix the leak and it is time for a new (or used) tire, give us a call! We would be glad to help you.
