- Uneven tread wear. You can check the tread depth by using a regular coin. If the coin disappears between the treads, you still have enough tread. However, if the coin is visible and the tread is worn, you should replace your tires.
- Cracking. Cracks in the sidewalls can be a sign of dry rot, which weakens the tire and makes it more susceptible to blowouts.
- Bulges. If you see any bulges or bulges on the side of the tire, it means the tire has weakened and needs to be replaced.
- Tread separation. Tread separation occurs when the tread detaches from the rest of the tire. This is a serious safety hazard and can lead to a blowout.
In general, it's recommended that you replace your tires every 6-10 years, or after they have reached the recommended tread depth. However, you should inspect your tires regularly for any signs of wear and tear, and replace them sooner if necessary.
