Tire Pressure Drops when Temperature Drops

Here is an easy tip for you to ensure you are driving safely this fall and upcoming winter season. Our professional mechanics in West Hartford advise that for every 10 degrees drop in temperature, tire pressure decreases one to two pounds per square inch (PSI). Checking the tire pressure is important for gas mileage, vehicle safety and tire life. Do you ever notice that when the weather gets colder the tire pressure lights starts flashing in the morning or night? Often drivers will see this in the morning when it’s coldest. If the temperature warms up during the day the light could turn off, but it’s likely that tires will still be a few PSI under inflated. This is why it’s important to check tire pressure regularly!

Another tip which could save you some $$$ is that incorrect tire pressure can lower gas mileage by 0.3 percent for every one PSI drop in pressure. When you notice and resolve the issue you will improve fuel efficiency by up to 3.3 percent.

Our experts advise that tire pressure should be checked monthly at the minimum. Note that newer cars with tire pressure monitoring systems may not alert you until the tire is significantly under inflated so keep your eye on that. Do yourself and your wallet a favor and check your tire pressure on the 1stof every month. Also during the colder winter months it’s smart to check them every couple weeks.
