Winter in Georgia certainly isn’t boring! With temperatures fluctuating from hot to cold this month, you may have noticed your tire pressure light going on.
The Science of Temperature and Air Pressure
Have you ever wondered why air pressure changes with the weather (or even while driving your car)? There is a direct relationship between temperature and air pressure. Hot temperatures cause gases to expand. This is why summer weather (or simply driving your car) can cause your tires to over inflate. Likewise, cold temperatures cause gasses to constrict. Again, this is why cold weather cause tires to (temporarily) deflate.
How Often Should I Check Tire Air Pressure?
First of all, you should always check tire pressure “cold” (i.e. when your car has been resting for a bit). Checking it while hot can cause an improper reading and can result in too low of tire pressure. Under normal circumstances, tire air pressure should be checked monthly. If you strike a curb, run over something sharp, or if there’s a cold snap, you should consider checking it more often.
