“Make sure you check your tire pressure, especially before and during winter. A change in temperature can change your tire inflation. For every 10 degrees the temperature changes, you can lose or gain up to 4 psi. Keeping your tires properly inflated can also save you money at the gas pump.”
Psi = parts per square inch, used to measure tire pressure.
