What are the signs of bad tires?

Bad tires can compromise the safety and performance of your vehicle. Here are some common signs that indicate your tires may need attention or replacement:

1. Low Tread Depth
• Sign: If the tread is worn down to 2/32 of an inch (1.6 mm) or less, it's time to replace the tires.
• How to Inspect: Use a tread depth gauge or the penny test (insert a penny with Lincoln’s head facing down—if you can see all of his head, the tread is too low).
2. Cracks or Bulges
• Sign: Visible cracks on the sidewalls or bulges on the surface are signs of structural damage.
• Cause: These can result from hitting potholes, curbs, or normal wear over time, increasing the risk of a blowout.
3. Vibration While Driving
• Sign: Excessive vibrations or shaking while driving, especially at higher speeds.
• Cause: It could be due to unbalanced or misaligned tires, worn-out treads, or internal tire damage.
4. Uneven Tire Wear
• Sign: Some areas of the tire wear down faster than others.
• Cause: This can be a result of improper alignment, over- or under-inflation, or suspension issues.
5. Tire Pressure Problems
• Sign: Constantly needing to inflate the tires or noticing that they frequently lose pressure.
• Cause: Leaks due to punctures, valve stem issues, or damage to the tire's structure.
6. Blisters or Bubbles on the Tire Surface
• Sign: A bubble-like bulge on the tire’s outer surface.
• Cause: This indicates a weak spot in the tire, usually caused by impact damage, and could lead to a blowout.
7. Excessive Tire Noise
• Sign: Worn tread reduces traction, making it harder for your car to grip the road, particularly in bad weather.
• Cause: This could be a result of worn-out treads or uneven wear patterns.
8. Worn-Out Indicator Bars
• Sign: Many modern tires have tread wear indicator bars. If the bars become visible, it means the tread has worn down significantly.
• Cause: These are designed to alert you when the tire needs replacing.
9. Longer Stopping Distances
• Sign: Your vehicle takes longer to stop, especially in wet conditions.
• Cause: Worn tread reduces traction, making it harder for your car to grip the road, particularly in bad weather.
