Your tires are the only part of your car that actually touch the road — and that makes them one of the most important safety features on your vehicle. Good tire tread is essential for keeping you safe, especially in wet or slippery conditions.
But how do you know when it’s time to replace your tires? Checking your tire tread is quick and easy, and it can help you avoid accidents and expensive repairs down the road.
Why Tire Tread Matters
Tread is the patterned part of your tire that grips the road. As your tires wear down over time, the tread becomes shallower, reducing traction. This can lead to:
- Longer stopping distances
- Increased risk of hydroplaning in wet weather
- Less control on snow or ice
- Higher chance of tire blowouts
How to Check Your Tire Tread
The Penny Test
One of the simplest ways to check tread depth is the penny test:
- Take a penny and insert it into the tread groove with Lincoln’s head facing down.
- If you can see the top of Lincoln’s head, your tread is too worn and it’s time to replace the tire.
- If part of Lincoln’s head is covered, you have enough tread for now.
Look for Tread Wear Indicators
Most tires have built-in tread wear bars — small, raised sections in the grooves. When these bars are level with your tread, it means your tires have worn down to the minimum safe depth.
Use a Tread Depth Gauge
For a more precise measurement, you can buy a simple tread depth gauge at an auto parts store. Insert it into the groove and check the reading.
- New tires usually have around 10/32″ to 11/32″ of tread.
- Replace them at 2/32″ or sooner if you drive in rain or snow often.
When to Check Your Tires
- Every month
- Before long road trips
- If you notice your car slipping or handling differently
- After hitting potholes or curbs
Other Things to Look For
While checking tread, also inspect for:
- Uneven wear (which could indicate alignment issues)
- Bulges or cracks
- Nails or objects stuck in the tire
Final Thoughts
Tires are critical for your safety and your car’s performance. Regularly checking your tread helps you catch problems early, avoid accidents, and extend the life of your tires. It only takes a minute, but it can save you a lot of trouble down the road.
