Your tires are your vehicle's only contact with the road. Ensuring they’re in good shape—especially the tread depth—is critical for your safety and performance. DM Motorsports in Midland Mint Hill, NC recommends checking your tire tread regularly to avoid premature wear, loss of traction, and dangerous driving conditions.

Why Tread Depth Matters

Tread depth affects:

Traction: Deeper treads grip better, especially in wet or slippery conditions.
Stopping Distance: Worn-out treads increase the distance it takes to stop.
Hydroplaning Risk: Shallow tread can’t disperse water efficiently.

Driving with low tread is not just dangerous—it can also be illegal. Most states require a minimum tread depth of 2/32 of an inch.

3 Easy Ways to Check Tread Depth

1. The Penny Test

Take a penny and insert it into the tread with Lincoln’s head facing down.
If you can see all of Lincoln’s head, it’s time for new tires.
If part of his head is covered, your tread is likely safe.

2. Tread Wear Indicators

Most tires have built-in wear bars running perpendicular to the tread.
If the tread is level with these bars, the tire needs replacement.

3. Tread Depth Gauge

A handheld tool that provides a precise tread depth reading in 32nds of an inch.
Readings of 4/32 or less suggest it’s time to monitor wear closely.
Readings at or below 2/32 mean it’s unsafe and time to replace.
