If your tires appear to be low, check the pressure and note the
amount that they’re under-inflated. Then drive to a local gas station and add
air. It’s easy, but be sure to bring some change (usually quarters) with you
for the air dispenser. (Forget about things being “as free as air” — at many
stations it isn’t!)
Follow these steps to add air to your tires:
1. Park your vehicle by
the air dispenser.
You will need to reach all four tires with the
air hose.
2. Remove the cap from
the tire valve on the first tire.
3. Use your tire gauge to
check the air pressure in the tire.
Air hose gauges at many gas stations are
inaccurate.
Checking your tire
pressure.
The pressure will have increased because
driving causes the tires to heat up and the air inside them to expand. To avoid over-inflating the tire, no matter what the second reading indicates, you should
only add the same amount of air that the tire lacked before you drove it to the
station.
4. Use the air hose to
add air in short bursts.
Check the pressure after each time with your
tire gauge.
If you add too much air, let some out by
pressing the pin on the tire valve with the back of the air hose nozzle or with
the little knob on the back of the rounded end of the tire gauge.
5. Keep checking the
pressure until you get it right.
Don’t get discouraged if you have to keep
adjusting the air pressure. No one hits it on the head the first time!
