Tread Depth Tire Gauge

We all know how to use a penny to measure tread depth. If it's level with Abe's beard, you need new tires. Or is it his nose? Or do you turn the penny upside down? This dual-purpose gauge removes the guesswork. It's an accurate, easy-to-read tire gauge, but it also measures tread depth from 0 to 19/32". Red, yellow or green indicators tell you when it's time for new tires. Storage pouch and coin cell battery included. Measures 2 1/2" x 1 1/4" x 3/4".
