How To Check if Your Tires are Bad

At Cable Dahmer, we want to ensure your vehicle is functioning safely on area roads. Part of that means taking good care of your tires. And there are actually a few ways that you can do that without needing to come into the dealership. By following these tips, you will have peace of mind that your tires are in good health.

Check Tire Pressure Monthly

Maintain proper tire inflation by checking the pressure at least once a month. Use a reliable pressure gauge to measure when the tires are cold, ideally before driving or after the car has been parked for at least three hours. Compare the readings to the recommended pressure listed on your vehicle's doorjamb or in the owner's manual, not the maximum pressure on the tire sidewall.

All modern vehicles do offer some kind of tire pressure monitoring system, TPMS, but it is still a good idea to manually check tire pressure just in case.

Inspect Tread depth

Adequate tread depth is essential for traction and safety. Use the penny test to check your tread:

  1. Insert a penny into the tread groove with Lincoln's head upside down and facing you.
  2. If you can see all of Lincoln's head, your tread depth is less than 2/32 inch, and it's time to replace your tires.


For a more precise measurement, use a tread depth gauge or the quarter test (if the tread touches Washington's head, you have at least 4/32 inch remaining).

Examine Tire Condition

Visually inspect your tires for:

  • Cuts, scrapes, or punctures
  • Bulges or bumps
  • Cracks in the sidewall
  • Uneven wear patterns

Any of these issues may require professional attention or tire replacement.

Check Tire Age

Locate the DOT code on the tire sidewall to determine the manufacturing date. The last four digits represent the week and year of manufacture. Consider replacing tires that are more than 6-10 years old, even if the tread appears adequate.

Rotate and Align

Regular tire rotation (every 5,000-7,500 miles) and wheel alignment (annually) help ensure even wear and extend tire life. While you can certainly rotate your tires yourself, our team at Cable Dahmer makes the process quick and easy. We can even perform a full tire inspection to make sure everything is as it should be.
