Not sure if your tires need replacing? You’re not alone. Knowing the right time to replace your tires can prevent accidents, improve fuel economy, and save you money in the long run. In this guide, we’ll break down the signs to look for and how to check your tires at home.
How Often Should Tires Be Replaced?
Tires should typically be replaced every 6 to 10 years, or when tread depth reaches 2/32 of an inch—whichever comes first.
However, not all tires wear the same. Your driving habits, road conditions, weather, and maintenance habits all affect tire life. That’s why checking your tires regularly is essential.
Top Signs It’s Time to Replace Your Tires
1. Low Tread Depth
The minimum legal tread depth in most areas is 2/32 of an inch. But safety experts recommend replacing them at 4/32” or even 5/32” in rainy or snowy climates. Less tread = less traction.
How to check: Use a penny. Insert it head-down into the groove. If you see all of Lincoln’s head, the tread is too low.
2. Visible Damage
Look out for:
- Sidewall cracks or bubbles
- Punctures or deep cuts
- Cord or steel showing through
Any of these are serious safety concerns. If you spot them, don’t wait—replace the tire immediately.
3. Uneven Wear
If the tread wears more on one side or in the center, something’s wrong. It could be poor alignment, wrong tire pressure, or suspension issues. Uneven wear shortens tire life and hurts performance.
4. Age of the Tire
Even if tread looks fine, old tires degrade over time. Rubber hardens, reducing grip and raising the risk of blowouts. Most tire makers recommend replacement after 6 years, and never using tires older than 10 years.
How to check the age:
Find the DOT code on the sidewall. The last 4 digits show the week and year. For example, “1019” means the 10th week of 2019.
5. Frequent Vibration or Noise
Feel shaking or hear odd noises while driving? It might not be your alignment—it could be tire damage or internal separation. Get them inspected ASAP, and replace if needed.
How Long Do Tires Usually Last?
| Type of Tire | Average Lifespan |
|---|---|
| All-season tires | 50,000–70,000 miles |
| Performance tires | 30,000–50,000 miles |
| Winter tires | 3–5 seasons |
| Off-road/mud tires | 30,000–40,000 miles |
Pro Tip: Even if mileage is low, replace tires based on age, condition, and safety—not just distance driven.
When Not to Wait: Replace Immediately If…
- You see bulges, blisters, or bubbles in the sidewall
- Tires are over 10 years old
- Cords or metal wires are showing through
- You had a flat tire that can’t be safely repaired
How to Extend the Life of Your Tires
You can get the most from your tires by following a few simple tips:
- Rotate every 5,000–8,000 miles
- Keep them properly inflated—check monthly
- Align your wheels yearly or if you hit a big pothole
- Inspect for wear and damage regularly
- Avoid sudden braking and sharp turns
Don’t Forget Your Spare Tire
Spare tires also age—even if they’re never used. If your spare is over 6 years old, it may not be safe. Check the date code and replace it if needed. You don’t want to discover a bad spare in the middle of nowhere.
Check Tire Health Along with Your Battery
While checking your tires, take a look at your battery too. A weak battery can leave you stranded—and most people replace theirs far too soon.
