The Ultimate Guide to Tire Tread Depth and Safety


Your tires are the only contact point between your vehicle and the road. Their condition plays a crucial role in your safety, fuel efficiency, and driving comfort. One of the most critical aspects of tire maintenance is monitoring tread depth.


Why Tread Depth Matters


Tread depth is essential for maintaining grip, especially in wet conditions. The grooves in your tires are designed to channel water away from the contact patch. As the tread wears down, the tire's ability to displace water decreases, significantly increasing the risk of hydroplaning.


How to Check Your Tread Depth


There are several ways to check your tire tread depth:


1.The Penny Test: Place a penny into a tread groove with Lincoln's head upside down. If you can see all of Lincoln's head, your tread depth is less than 2/32 inch and it's time to replace your tires.
2.Tread Wear Indicators: Modern tires have built-in tread wear indicator bars. These are small rubber bars at the bottom of the tread grooves. When the tread is flush with these bars, the tire is worn out.
3.TireCheck App: Use our AI-powered tool to instantly analyze your tire tread depth using just a photo.

When to Replace Your Tires


Most manufacturers and safety experts recommend replacing tires when the tread depth reaches 2/32 of an inch (1.6mm). However, for better safety in rain and snow, consider replacing them at 4/32 inch (3mm).


Stay safe and check your tires regularly!
