Things You'll Need:
- Tread depth indicator
- Tire gauge
- Air pump
-
Step 1
Unscrew the valve cap on the tire of your car. Be sure to keep the cap close by as it will be needed later on to cover the valve.
-
Step 2
Place tire gauge over the opening of the valve where the cap was. Be sure the gauge is firmly on the valve.
-
Step 3
Compare the pressure reading of the gauge to the number your user manual (or sometimes side door) says the tire should be at.
-
Step 4
If the pressure amount is less than the recommended amount, add air to the tire using an air pump (found at most gas stations or auto/home improvement stores) then repeat the check until the tire's air pressure is at a satisfactory level.
-
Step 5
Replace the valve cap by screwing it on tightly.
-
Step 6
Use a tread depth indicator to be sure the tire still has enough tread. If not, it needs to be replaced.
-
Step 7
Look over your tire, check to see if there are any cracks, nails or an uneven amount of wear on your tires. Some of the common problems that cause tires to become damaged sooner are over inflation, under inflation and misalignment.
-
Step 8
Inspect the inner sidewall. If there is a fluid, it may mean that your brake fluid is leaking. If so, inspect the brakes.
-
Step 9
Repeat steps for all 4 tires.
