How Often Should You Replace Your Tires?

Your tires are your car’s part that contacts the road — yet they are perhaps the most ignored. There are so many drivers wondering: How often should you replace your tires? It depends on several factors – how many miles you have, your age, how you drive, and what the visual signs are. This ultimate guide will highlight how to check the condition of your tires, what the average life of a tire is, and how to notice tire wear signs before safety becomes an issue. 

How Long Do Tires Last?

Tires typically last between 25,000 and 50,000 miles, depending on the tire type and use. High-performance tires, typically sports cars, can wear out at an even faster pace — 20,000 miles. However, seasonal tires usually fall more on the higher side. Mileage is only part of the factor. Signs of aging in tires, such as cracks in the rubber or sidewall bulges, can signal that it may be the right time to replace your tires. 

Manufacturer Guidelines

Most manufacturers recommend changing tires every 6 years with a maximum life of 10 years. Rubber gets old in the same way that an old rubber band slowly snaps when you pull it.

Pro Tip

Check the D O T code printed on your tire’s sidewall to discover the week and year it was manufactured. For example, “3519” means the tire was made in the 35th week of 2019.

Signs You Need New Tires

Understanding how to tell if you need new tires is important for road safety. Here are some warning signs:

1. Tread Depth Is Too Low

Tread gives grip and takes water away from the contact patch. When tread becomes too thin, your stopping distance increases dramatically, particularly on wet roads.

One common rule is the “penny test”: Insert a penny head-down into your tire tread. If you see all of Lincoln’s head, your tread is below 2/32”, and the time to replace the tire.

Tip: Consult a tire tread depth chart to compare the measurements and legal safety standards.

2. Visible Tire Wear Indicators

Modern tires include a set of built-in wear bars that become flush with the tread surface as they wear. If these bars are level with the tire, you’ve reached the minimum legal tread depth.

3. Cracks, Bulges, or Uneven Wear

• Cracks = aging rubber
• Bulges = internal damage or sidewall failure
• Uneven wear = alignment or inflation issues

Any of these symptoms should prompt immediate replacement.

4. Vibration While Driving

If your steering wheel is shaking or vibrating, especially at highway speeds, it’s usually a sign that you have either worn tires, out-of-balance wheels, or suspension problems. Start with a tire check.

When to Replace Tires Based on Use Case

Even if tread may be fine, tires can be dangerous at any age. Here are key indicators:

• Sidewall cracks or dry rot
• Fading black color (UV exposure damage)
• Loss of flexibility when touched
• Constant air pressure loss

These are signs that the rubber has worn and the tire’s strength has changed. Here’s a practical tire replacement schedule for most drivers:

Time/Mileage	What to Do
Every 5,000–8,000 mi	Rotate tires (ensures even wear)
Every 6 months	Inspect the tread and check for damage
At 30,000–50,000 mi	Assess tread depth and wear indicators
At 6 years old	Consider replacement regardless of use
At 10 years old	Mandatory replacement (per industry)

Conclusion

Understanding when to replace your tires is not only about mileage — it’s also about knowing your driving routine, tire condition and safety. By finding out about how to identify signs of tire wear, maintain a tire replacement calendar and check for indications of tire aging, you can trust in a smoother journey and decrease your chances on the road. Moreover, you don’t need a blowout to do something. When you check and replace your PSA, you keep yourself safe and your vehicle functioning properly.
