Proper tire inflation

With temperatures changing from below freezing to the 40 degree territory your tire pressure may be affected. You should take a few minutes to make sure yours are still at their normal operating pressure.
One of my tires was so far off I thought I needed an alignment because the car was pulling hard to the left. I found out one of my tires was off by 7 lbs of pressure after I had checked all of them a week prior! Air expands and condenses with changing temperatures and that is exactly what happened to me.
If you have a newer car with the Tire Pressure Monitoring System (TPMS), which is standard equipment in all cars now, then you may have already seen some warnings on your dashboard. If you have summer performance tires like I do, then you have probably seen those warning lights more often. Summer performance tires are even more susceptible to the changing air temperatures. Most sports cars have summer performance tires.
To check your tire pressure:
check your owners manual or on the sidewall of your tire (most tires have a PSI rating on the tire)
head to your local gas station to use the pressure gauge on the air pump and fill your tires as needed - cost is usually less than a dollar
or stop by Rothrock's Service Department to have us do it for you - we can also inspect your car for any other issues*
Keeping your tire pressure at the proper operating levels will save you money! It will increase your gas mileage and the life of your tires.
There are only a handful of instances where you might want low tire pressure:
offroading
driving in wintery conditions
on the race track
