5 Signs It’s Time to Replace Your Tires

Stay Safe on the Road

Your tires are the only part of your vehicle that makes contact with the road. That means their condition plays a direct role in how well your car handles, how safely it stops, and how comfortable your ride feels. Still, many drivers wait too long to replace worn-out or unsafe tires—often because they’re unsure what to look for.


At Raymond’s Tire Shop in Dorchester, we help Boston drivers stay safe by spotting signs of trouble before they turn into roadside breakdowns. If you’re wondering whether your tires still have life in them, here are five clear signs it’s time for a replacement.

1. Your Tread Is Too Low

Tread depth is one of the most important indicators of tire health. The grooves in your tire tread help it grip the road, especially in wet or slippery conditions. As the tread wears down, your risk of hydroplaning, sliding, or losing traction increases dramatically.


A good rule of thumb: use the penny test. Insert a penny into the tread with Lincoln’s head facing down. If you can see the top of his head, your tread is below 2/32 of an inch—and it’s time to replace the tire. Many experts recommend replacing at 4/32” for safety, especially in wet climates.



At Raymond’s, we measure tread depth during every inspection and help you decide whether replacement is urgent or simply on the horizon.

2. You Notice Cracks or Bulges

Rubber naturally breaks down over time, especially in extreme temperatures. If you see cracks in the sidewalls or tread surface, it could indicate dry rot or structural breakdown. Similarly, bulges or bubbles in the sidewall often mean that internal layers of the tire have been damaged—usually from potholes, curbs, or road debris.


These issues aren’t just cosmetic. A bulging tire can blow out without warning, especially at higher speeds. If you see anything out of the ordinary, don’t wait—get your tires checked immediately.

3. You Feel Vibration While Driving

Some vibration is normal on rough Boston roads, but if you notice a new or persistent vibration—especially at low speeds or on smooth pavement—it could point to uneven tire wear, misalignment, or internal tire damage.


In some cases, a vibration means the tire is out of balance or the belts inside the tire have started to separate. Either way, it’s a sign that your tires are no longer providing a stable, consistent ride.


If you’re not sure what’s causing the shake, bring your car to Raymond’s Tire Shop. We can inspect for damage, rebalance your wheels, and let you know if it’s time for new rubber.

4. You’ve Had One Too Many Patches

Getting a flat fixed is a cost-effective solution—but only up to a point. If a tire has been patched multiple times, especially near the sidewall or shoulder, it’s more likely to fail under pressure. Most manufacturers recommend no more than two patches per tire, and only if they’re in repairable locations.


If your tire looks like it’s been stitched back together too many times, it’s probably time to retire it and move on to a safer set.


5. They’re Just Old

Even if your tires look fine, age alone can make them unsafe. Most manufacturers suggest replacing tires every six to ten years, regardless of tread wear. Over time, rubber hardens and loses flexibility, making the tire more prone to cracking or failure.


You can check your tire’s age by reading the DOT code on the sidewall. The last four digits represent the week and year of manufacture. For example, a tire stamped “3219” was made in the 32nd week of 2019.



If your tires are over six years old, especially if they’ve been exposed to a lot of sun or harsh weather, it’s worth considering a replacement—even if the tread still looks good.
