Keep your tires safe and legal with this compact Tire Tread Depth Gauge!
This tool helps you instantly measure tread depth to see if your tires still meet the legal minimums:

• Winter tires: 4 mm reference
• Summer tires: 1.6 mm reference

Features:

1. Keychain hole to keep it always with you
2. Easy-to-read step design
3. Small, durable, and print-friendly (PETG or PLA recommended)

Use it by simply placing the gauge in the tire groove. If the tread is flush with the indicator step, it’s time to replace your tires.
