Things You'll Need:
- Tire pressure gauge
-
Step 1
Look at the tires for uneven wear, damage, cracking or embedded nails. Replace or repair the tires as needed. Uneven wear may indicate over or under inflation, misalignment or that the tires need rotating.
-
Step 2
Inspect the tread. Check for tire wear bars—bars in the tires across the treads. If you see these, the tire needs replacing. You can also take a penny and insert it into the tire groove with Lincoln's head upside-down. If you see all of Lincoln's head, the tire's too worn and needs replacing. Make sure you check the tread in all four tires—not just one. This is also a good way to check for wear; if the tread is different in different areas, the tire's not wearing correctly and may need replacing.
-
Step 3
Check your tires' pressure (PSI) with a tire pressure gauge when it's cold outside and you haven't used the car for a few hours. Insert the gauge into the nozzle on the side of the tire called the tire's valve stem. Press the gauge down until you don't hear a hiss of air. Note the reading on the tire pressure gauge. Look for a sticker on the driver's side door that lets you know what the maximum tire pressure should be for your tires.
-
Step 4
Add or subtract air to your tires if your PSI indicates it. Adding air to a tire is easy with a simple air pump available at auto repair shops or at gas stations. You can subtract air from tires by pressing on the metal stem in the center of the valve with a pen tip. Once you add or subtract air from tires, don't forget to double check the PSI again.

Step 5
Verify previous owners of your Plymouth Voyager have put the correct size tires on your van. If you have to replace the tires, make sure you use the correct size tires. Go to GoodyearTires to search for the correct size tires.
