Introduction We often take our tires for granted until something goes wrong. Worn-out tires drastically increase your braking distance and risk of hydroplaning. But how do you know when it’s time to replace them? Here are five warning signs every driver should watch out for.
1. Low Tread Depth (The Penny Test) In most states, the legal minimum tread depth is 2/32 of an inch. A simple way to check this is the "Penny Test." Insert a penny into your tire's tread groove with Lincoln’s head pointing down. If you can see the top of his head, your tread is too low, and it’s time for new tires.
2. Uneven Tread Wear If one side of your tire is significantly more worn than the other, it could indicate poor wheel alignment, improper balancing, or incorrect tire pressure. While a mechanic can fix the underlying issue, severely uneven tires will need to be replaced.
3. Cracks in the Sidewall Over time, exposure to UV rays and extreme temperatures can cause the rubber in your tires to dry out and crack. If you notice visible cracks or cuts in the sidewall, your tire is at risk of a blowout.
4. Excessive Vibration While Driving While a little vibration on rough roads is normal, excessive shaking on smooth roads—especially at highway speeds—often indicates internal tire damage or a balancing issue. Don't ignore this symptom.
5. Age Even if your tires have plenty of tread left, the rubber degrades over time. Most manufacturers recommend replacing tires every 6 to 10 years, regardless of mileage. Check the DOT code on the sidewall to find the manufacturing date.
