Multiple symptoms indicate that your tires are worn or need repair. The most evident sign (besides a flat tire) is vibrations or pounding. If you notice this and it feels like it’s coming from under the seating area, it might mean your rear tires are unbalanced. If your vehicle pulls to one side while driving, one of your tires could be low on pressure, with the direction of the pull indicating which tire is affected.

When performing a visual inspection of the tires, look for cracks or bumps, which suggest external issues that could lead to slow air leaks. Although your tires might be salvageable, it’s always better to get a professional opinion.

Tread depth is another crucial aspect to consider. Tread helps your tires maintain traction, especially in slippery conditions. You can check your tire’s tread level using a penny. Place the penny upside down in the tread; if you can see the top of the president’s profile, there isn’t enough tread, and you should consider replacing the tires.
