Tires are the most vital safety component of your car. They're the only component that touches the road, and yet most drivers have no idea when to replace their tires. Waiting could mean lower traction, longer stopping times, and even blowouts. Fortunately, your tires will signal it's time to swap to a new one.
This blog will show the most popular tire wear indicators and explain why driving on worn-out or old tires is risky.
Good tires give you traction, stability, and control. Old tires, however, are a serious safety hazard. When to replace tires is something you may not know, but remember that bad traction can force you to slow down to be able to stop, particularly in rain or snow. Old tires also heighten the risk of hydroplaning and accidents.
These are some of the most important signs that you need new tires.
Tread is the road-facing tire surface that is treaded. Tread wears out over time. Shallow tread is among the most visible indications of tire wear that your tires must be replaced.
Use the "penny test" as an approximation of tread depth:
Take a penny and place it into your tire tread with Lincoln's head facing downward.
If you can see the entire head of Lincoln, your tread is too low, and your tires need to be replaced.
All professionals agree that you need to replace your tires when the tread is below 2/32 of an inch. Many safety agencies recommend that you replace them earlier—at 4/32 of an inch—particularly for wet or snow weather driving conditions.
Even if your tread depth appears fine, inspect for uneven wear. If the wear on one side of your tire is greater than on the other, it may indicate misalignment, suspension, or improper inflation.
Doing a periodic tire safety inspection can make you notice this in time. Being able to catch uneven wear early will make you be able to address the problem and prolong the life of the tires. But once it is already serious, you should replace the tire for your own safety.
Any visible physical damage to the tire wall is a red flag signifying something is amiss. If you see cracks, bulging areas, or bubbles, don't take anything for granted.
These symptoms typically indicate that the internal tire construction has been compromised. Operating on worn-out tires is hazardous and may cause a blowout. Tires exhibiting any of these symptoms must be replaced as soon as possible.
Even if your tires appear to be good, they can still be replaced based on age. Rubber deteriorates with time, even though the tread is not completely worn out. This is a silent old tire danger.
Most companies suggest replacing tires every six to ten years. To find the date manufactured, look at the four-digit number imprinted on the sidewall of the tire. If it reads "3018," for instance, then the tire was manufactured in the 30th week of 2018.
Older tires are more prone to fail, particularly when it's hot or you're under stress.
If you notice ongoing vibration or shaking while driving, especially at highway speeds, it could be a sign that your tires are damaged or out of balance. While in some instances this could signify wheel alignment or suspension, it might also be a sign of something involving the tires.
If you've balanced and rotated your tires but are still experiencing vibration, it's time to get a tire safety check. A mechanic will be able to diagnose whether your tires are the problem, and whether they need to be replaced.
Does your car pull to one side, even if you hold the steering wheel straight? Or does it ride a bit farther before stopping? These subtle variations in handling may be telling you that your tires are wearing unevenly or not gripping as well as they once did.
Whenever your car doesn't feel as solid or responsive, it's time to wonder whether it's time to replace your tires.
The majority of tires have built-in tire wear indicators—little bumps along the grooves of the tread. When the tread is worn to the same height as the bumps, it's time for a tire.
These wear indicators are put in the tread to be easily seen once the tire has reached the legal or safe minimum. Add checking them to your monthly maintenance routine. If you notice these wear indicators flush with the tread surface, your tires are no longer safe.
There's an easy-to-use tread depth guide to help you make the decision when to replace tires:
Most tire stores will have a tread depth gauge tool, or they can check it for you for free. Either way, don't let your tires get down to the bare minimum.
It is unsafe to drive on worn-out tires, even if they've only been used sparingly. Over time, they will wear out from exposure to air, heat, and sunlight. As the tire grows older, it becomes more brittle and susceptible to cracking or splitting under pressure.
Old tire risk is especially important in hot weather or for long driving. Don't judge them by looks alone—look at the date of manufacture and replace tires that are more than six years old, even if they look like new.
The season also dictates when to replace tires. Some seasonal tire advice to keep you safe is discussed below:
Rotating your tires every 5,000–8,000 miles and having the alignment inspected will also keep them evenly worn throughout the year.
The following are steps on how to simply conduct a tire safety check in just a few minutes:
Make tire inspections a regular habit—monthly and prior to any extended drive.
It is easy to put off replacing tires for cost reasons. Remember, though, that riding on substandard tires may result in accidents, towing fees, or even loss of your vehicle. Four new tires are well worth the expense of a wreck or emergency service.
New tires also enhance fuel economy, ride quality, and confidence.
Your tires will not last forever. And because they will not be screaming for help like your engine or brakes might not mean that they do not have a critical role in your safety.
Be aware of tire wear indicators, consult a basic tire tread depth guide, and check your tires for safety regularly. You do not need to believe the old tire threat—it's better to be safe than sorry.
