When Should You Change Your Car Tires?

Your tires keep you safe on the road. Worn tires increase stopping distance. They also increase the risk of hydroplaning. You need to know when to replace them. Look for these clear signs.

Car Tires: Check Your Tread Depth

Tread grips the road. Worn tread loses this ability. Use the penny test to check depth. Insert a penny into the tread groove with Lincoln’s head upside down. If you see all of Lincoln’s head, your tread depth is too low. Replace the tires immediately. The legal minimum tread depth is 2/32 of an inch. The penny test confirms this.

Look for Tread Wear Indicators

Modern tires have built-in wear bars. These are small bridges in the grooves. When the tread wears down to the level of these bars, the tires need replacement. The bars will appear as flat rubber strips across your tread.

Inspect for Sidewall Damage

Examine the sidewall of each tire. Look for cracks, cuts, or bulges. Cracks show the rubber is degrading. Cuts will expose internal cords. Bulges indicate internal damage. These problems will cause a sudden blowout. Replace a tire with any sidewall damage.

Understand Tire Age

Tires age even with good tread. Rubber compounds break down over time. The U.S. Department of Transportation requires a Tire Identification Number. Find this number on the sidewall. It starts with DOT. The last four digits show the week and year of manufacture. For example, 3521 means the 35th week of 2021. Many manufacturers recommend replacing tires esix to ten years. Check your owner’s manual for specific guidance.

Feel for Vibration

Pay attention to how your car feels. New vibrations while driving often indicate tire problems. The issue might be internal damage or improper alignment. Have a professional inspect your tires if you feel new vibrations.

Check Tire Pressure Often

Check your tire pressure monthly. Tires lose pressure over time. Consistent pressure loss in one tire suggests a slow leak. This leak might be from a puncture or valve stem issue. Repair or replace the tire as needed.

Your safety depends on your tires. Perform these checks emonth. Replace tires with low tread, visible damage, or advanced age. Consult a tire professional for any questions about your specific tires.
