Knowing when to replace your tires is crucial for your safety and your vehicle’s performance. One of the most common signs is low tread depth. As tread wears down, tires lose traction – especially in wet or slippery conditions.
A simple way to check is the penny test: insert a penny into the tread with Lincoln’s head down – if you can see the top of his head, it’s time for new tires. Most experts recommend replacing tires when tread depth reaches 2/32 of an inch.
Another key indicator is visible damage. Look for cracks, cuts, or bulges in the sidewalls, which may indicate internal tire damage or a weakened structure. Such issues can lead to blowouts if left unaddressed. Similarly, if you notice vibration or thumping while driving, it could point to tire imbalance, uneven wear, or internal defects – each of which are signs that replacement may be necessary.
Age is also a factor. Even if your tires appear in good shape, manufacturers generally recommend replacement every six to ten years, regardless of tread depth, due to rubber degradation over time.
Uneven wear patterns such as more wear on one side of the tire can result from misalignment, improper inflation, or suspension issues. If caught early, a tire rotation or alignment can help; if not, the tires may need replacing sooner than later.
Finally, if it’s taking you longer to stop – especially in rain or snow – your tires may no longer be safe. Paying attention to these signs of tire wear can help protect you and your passengers on the road.
