When should you change Tires?

Tires are an essential component of your vehicle, ensuring a smooth and safe driving experience. Over time, however, they wear down and require replacement. But when exactly should you change your tires? This comprehensive guide will help you understand the factors that contribute to tire wear and when it’s time to invest in new ones.

6 Reasons to Change Tires

According to Tire Reviews, you should change your tires when the tread depth falls below the legal minimum (usually 2/32 inches or 1.6 millimeters), the tires are six to ten years old, they show signs of uneven wear, damage, or punctures, or you experience performance issues. Additionally, switch between summer and winter tires based on seasonal changes. Regular maintenance, including a tire rotation, proper inflation, wheel alignment, and suspension upkeep, can help extend tire life.

Below are the detailed 6 reasons to change the tires:

  1. Tread Depth

One of the most critical factors to consider when determining if it’s time to change your tires is tread depth. Tread depth affects your vehicle’s traction, braking, and overall stability. The legal minimum tread depth varies depending on the country or state you’re in, but as a general rule, 2/32 inches (1.6 millimeters) is the minimum allowable depth.

To measure your tire’s tread depth, you can use a tread depth gauge, a coin, or even your own fingers. If the tread depth is below the legal minimum, it’s time to change your tires.

  1. Tire Age

Tires naturally degrade over time due to the effects of heat, sunlight, and ozone. Even if your tires have plenty of tread depth, they may still be unsafe if they’re too old. Most tire manufacturers recommend replacing tires that are six to ten years old, regardless of their apparent condition.

To determine the age of your tires, check the DOT (Department of Transportation) code printed on the sidewall. The last four digits of the code represent the week and year of manufacture. For example, a code ending in “3221” indicates that the tire was made in the 32nd week of 2021.

  1. Uneven Wear

Uneven tire wear can result from various factors, including misaligned wheels, improper inflation, and worn suspension components. When tires wear unevenly, they can compromise your vehicle’s handling and braking capabilities.

Regularly inspect your tires for signs of uneven wear, such as one side of the tread wearing faster than the other or a “cupping” pattern on the tire surface. If you notice uneven wear, consult a professional mechanic to address the underlying issue and replace the affected tires.

  1. Damage and Punctures

Sometimes, tire damage is severe enough to warrant immediate replacement. Inspect your tires for cuts, punctures, sidewall bulges, or other visible damage. If the damage is beyond repair or compromises the tire’s structural integrity, it’s time for a replacement.

  1. Performance Issues

If you’ve noticed a decrease in your vehicle’s performance, such as poor handling, vibrations, or increased road noise, it may be time to change your tires. Worn or damaged tires can negatively impact your vehicle’s performance, making it crucial to address the issue promptly.

  1. Seasonal Changes

In regions with significant seasonal weather changes, it’s essential to switch between summer and winter tires. Summer tires are designed to perform optimally in warm, dry conditions, while winter tires provide better traction and performance in cold, snowy, or icy conditions. Failing to change your tires for the appropriate season can result in decreased performance and increased wear.

How to Extend the Life of Your Tires

To get the most out of your tires, consider the following maintenance tips:

  1. Regular Tire Rotation: Rotating your tires every 5,000 to 7,000 miles (8,000 to 11,000 kilometers) helps ensure even wear across all four tires, prolonging their lifespan.
  2. Proper Inflation: Maintaining the correct tire pressure is essential for even tire wear and optimal performance. Check your vehicle owner’s manual or the sticker inside the driver’s door for the recommended tire pressure.
  3. Wheel Alignment: A properly aligned vehicle ensures that all four tires make even contact with the road, minimizing uneven wear. Schedule a wheel alignment check at least once a year or whenever you notice signs of misalignment, such as your vehicle pulling to one side or uneven tire wear.
  4. Suspension Maintenance: Worn suspension components can lead to uneven tire wear and reduced handling capabilities. Regularly inspect and replace worn components to keep your vehicle running smoothly.


Knowing when to change your tires is crucial for maintaining a safe and efficient driving experience. By regularly monitoring your tires’ tread depth, age, wear patterns, and overall condition, you can make informed decisions about when it’s time for a replacement. Don’t forget to also practice proper tire maintenance, such as regular rotation, inflation, and alignment checks, to extend the life of your tires and save on unnecessary replacements. Remember, investing in quality tires and taking care of them is not only an investment in your vehicle’s performance but also in your safety on the road.
