During winter months the temperature can be 40 degrees Fahrenheit one day and below zero just a few days latter.
A change of 10 degrees Fahrenheit in air temperature will change your tire's inflation by about one psi (up with higher temperatures and down with lower).
You might think that your tires support the wieght of your vehicle, but they do not. It's the air pressure inside them. Maintaining proper air pressure is a must if your tires are to provide the best handling, traction and durability.
We have several excellent air pressure gauges to help you maintain proper psi and ensure the best performance and safety your tires can provide.
