You’re probably aware that your car’s tires won’t last forever, but exactly what clues should you look for when it comes to knowing when to replace them? Here are four signs that it may be time for new tires.

1. They’re Damaged

Getting a flat isn’t the only sign that you’ve got a damaged tire. A sharp object like a screw or a piece of glass may be embedded and can cause damage even if you can’t detect any air seeping out. Other tears or cuts in the sidewall may not puncture the tire, but they still may be deep enough to make them unsafe to drive on. Bubbling or distension in the sidewall or treads can also be a sign of internal damage. Inspect your tires regularly, and when needed turn to a brand such as Falken Tires for replacements.

2. They Aren’t Performing Properly

Tires that routinely need to be refilled with air aren’t just a hassle; they can also significantly impact your fuel economy and make your car difficult to operate. When your tires don’t stay properly inflated it can make it hazardous to drive in suboptimal conditions. Underinflation may cause them to blow out suddenly, which may lead to further danger. If you are adding air more than once a week, notice a vibration in the steering wheel or the car itself, or hear any humming or buzzing from your tires, it may be time for new ones.

3. Their Tread Is Worn Down

In general, the thicker your tire tread, the safer your car will be to operate. Traction and stopping time are both positively impacted by the condition of your tires’ treads. If there is significant uneven wear in your treads, it’s probably time to replace the affected tires; you’ll also want to have your alignment checked so the problem doesn’t persist. If the wear across your tires is fairly even, you’re still not out of the woods, as tread depth is also a factor in determining if your tires need replacing. The internet is full of measurement tricks like using coins to test tread depth, so there’s no excuse not to keep an eye on how well your tires are holding up under normal use.

4. They’re Old

Even well-maintained tires that have only been driven in mild conditions won’t last forever. If it’s been at least six years since you last replaced one or more of your tires, it may be time for a new set. Living in climates that get especially hot or cold, or driving more than 15,000 miles per year, may mean your tires need to be replaced even sooner than that. Keep track of when you purchase tires and watch out for web-like cracking on the sidewalls, which can indicate dry rot is setting in.

Visible damage, poor performance, worn tread, and age are all indicators that it may be time to replace your tires. Paying attention to these concerns can help you proactively address any potential issues before your car becomes hazardous to drive.
