How Often to Replace Your Tires

Tires are a crucial component of your vehicle, responsible for the safety and performance of your car on the road. Over time, they wear down due to regular use, road conditions, and weather, which can affect their grip, handling, and overall safety. Knowing when to replace your tires is essential for maintaining a safe and efficient driving experience. Keep reading to learn how often you should replace your tires and the signs that indicate it’s time for a new set.

Tread Depth

The most common method for determining when to replace tires is by checking the tread depth. Tread provides traction and disperses water from under the tires. Most tires have built-in tread wear indicators that are barely visible when the tire is new. When the tread is worn down to the level of these indicators, it’s time to replace the tires.

Tread Wear Bar

Tires also have tread wear bars that run perpendicular to the tread. When the tread wears down to the level of these bars, it’s a clear sign that the tires are no longer safe and need replacement.

Age of the Tires

Regardless of the tread depth, tires have a limited lifespan. Most experts recommend replacing tires every 6 to 10 years, even if they appear to have good tread remaining. This is because the rubber in tires degrades over time, and older tires are more susceptible to failure, especially under extreme conditions.


While there’s no fixed mileage at which you should replace your tires, the distance your tires can travel depends on various factors, including the type of tire, driving conditions, and maintenance. On average, tires may last between 25,000 and 75,000 miles.

Driving Conditions

If you frequently drive in harsh conditions, such as heavy rain, snow, or rough terrain, your tires may wear out more quickly. In such cases, you should inspect your tires more often and consider replacing them earlier.

Signs It’s Time to Replace Your Tires

  • Bald Spots: Check your tires for uneven wear or bald spots, which can indicate alignment issues or under-inflation. If you notice such wear, it may be time to replace your tires.
  • Cracks or Bulges: Inspect the sidewalls of your tires for cracks, cuts, or bulges. These issues can be signs of tire damage, and the tires should be replaced immediately.
  • Vibration or Pulling: If your vehicle vibrates excessively or if it pulls to one side, it could be due to tire issues. A tire that’s out of balance, damaged, or worn unevenly can cause these symptoms.
  • Reduced Traction: If you notice that your tires have less grip, especially in wet or slippery conditions, it’s a sign that the tread is worn, and it’s time to replace the tires.
  • Frequent Flats or Punctures: If you find yourself dealing with frequent flat tires or punctures, it may be a sign that your tires are no longer in good condition.
  • Increased Stopping Distance: When your tires are worn, it can take longer for your vehicle to come to a stop. If you notice an increase in stopping distance, consider replacing your tires.
