Your vehicle’s tires are the only point of contact with the road, making them one of the most critical safety components. Worn-out or damaged tires can reduce traction, affect handling, and increase the risk of accidents. But how do you know when it’s time for new tires?
In this guide, we’ll cover five clear signs that indicate it’s time to replace your tires—plus some tips to keep them in top condition for as long as possible.
1. Low Tread Depth (Bald Tires)
Tread depth is crucial for maintaining traction, especially in wet or snowy conditions. As tires wear down, their ability to grip the road diminishes, leading to longer stopping distances and increased risk of hydroplaning.
📌 How to Check Your Tire Tread Depth:
The Penny Test
- Insert a penny into the tire tread with Lincoln’s head facing down.
- If you can see the top of Lincoln’s head, your tread is too low (less than 2/32 inches or 1.6 mm) and it’s time for new tires.
The Quarter Test (For Extra Safety in Rain & Snow)
- Insert a quarter instead.
- If Washington’s head is visible, your tread is below 4/32 inches (3.2 mm), meaning your tires are not safe for wet or snowy conditions.
💡 Pro Tip: Winter tires should be replaced when tread depth reaches 5/32 inches (4 mm) for maximum snow and ice traction.
2. Cracks or Bulges on the Sidewalls
Tires naturally wear down over time, but visible cracks or bulges on the sidewall are warning signs of structural failure.
📌 What Causes Cracks or Bulges?
✔️ Age – Tires deteriorate from UV rays, oxygen exposure, and general wear.
✔️ Extreme Temperatures – Hot and cold weather can cause rubber to expand and contract, leading to cracks.
✔️ Underinflation – Driving with low tire pressure can weaken the sidewall, making bulges more likely.
✔️ Hitting Potholes or Curbs – Impact damage can create weak spots, leading to bulging or bubbles in the sidewall.
🚨 If you notice cracks or bulges, replace the tire immediately to prevent a dangerous blowout while driving.
3. Excessive Vibration or Rough Ride
A certain level of vibration is normal when driving, especially on rough roads. However, if you feel an increase in shaking or a rough ride, it could be a sign of tire problems.
📌 Common Causes of Tire-Related Vibrations:
✔️ Uneven Tread Wear – Tires wear unevenly if they are not rotated regularly.
✔️ Tire Imbalance – Unbalanced tires cause shaking at certain speeds.
✔️ Internal Tire Damage – A hidden defect or internal separation can cause a bumpy ride.
✔️ Alignment Issues – Misalignment can cause tires to wear unevenly, leading to vibrations.
💡 Solution: If you experience excessive vibration, get your tires inspected immediately. Ignoring the issue could lead to premature wear or even tire failure.
4. Uneven or Unusual Wear Patterns
Tire wear should be even across all four tires. If you notice one section wearing down faster than the rest, it’s a sign of an underlying issue.
📌 Common Types of Uneven Tire Wear:
| Wear Pattern | Cause | What to Do |
|---|---|---|
| Center Wear | Overinflation | Reduce tire pressure to manufacturer’s recommendation |
| Edge Wear | Underinflation | Inflate tires to proper PSI |
| Cupping (Wavy Wear) | Suspension problems | Get suspension checked and replace damaged components |
| One-Sided Wear | Wheel misalignment | Get a professional alignment to prevent further wear |
🚨 Ignoring uneven wear shortens tire lifespan and reduces performance. Regular tire rotations (every 8,000 km) and proper alignment help ensure even wear.
5. Tire Age (Even If They Look Fine)
Even if your tires have enough tread, they can still expire due to aging. Rubber degrades over time, making old tires more prone to cracking and failure.
📌 How Long Do Tires Last?
✔️ Most tires should be replaced after 6 to 10 years, regardless of tread depth.
✔️ Check the DOT code on the sidewall—it tells you the manufacturing date.
📌 How to Read the DOT Code:
- Example: DOT XYZ 4019
- 40 = 40th week of the year
- 19 = Manufactured in 2019
💡 Pro Tip: If your tires are over 6 years old, have them inspected by a professional—even if they look fine.
Bonus Tip: Regular Tire Maintenance Can Extend Their Life
🚗 Want your tires to last longer? Follow these maintenance tips:
✅ Check Tire Pressure Monthly – Proper inflation improves fuel efficiency and tread life.
✅ Rotate Tires Every 8,000-10,000 km – Helps prevent uneven wear.
✅ Get a Wheel Alignment Annually – Keeps your vehicle driving straight and extends tire lifespan.
✅ Inspect Tires for Damage – Look for cracks, bulges, or nails stuck in the tread.
✅ Avoid Sudden Braking & Hard Acceleration – Reduces excessive tread wear.
Final Thoughts: Don’t Wait Until It’s Too Late!
Your tires are the most important safety feature on your vehicle. If you notice any of the five signs above, it’s time to replace them to keep you and your passengers safe.
