How to Take Repeatable Tire Tread Depth Readings

Park on level ground. Follow the gauge instructions to set its zero, then place the probe inside a tread groove away from raised wear bars. Rest the base squarely on the tread so the gauge does not tilt.

What to check on the product

Digital tire tread gauge in the selected color. Check the unit shown on the display before recording a measurement. See the Digital Tire Tread Depth Gauge for Groove Measurements for the available options and additional photos.

Recording your measurements

Record the unit and position along with each reading. Compare inner, middle and outer grooves and repeat around the tire. If readings vary sharply or you see damage, have a tire professional inspect it.
