This AOMASO 2-in-1 tire gauge and tread depth gauge is a must have for all vehicle owners. It’s very compact in size and you can put it in the glove box so you have it anywhere you go. With a push of the power button, the color backlit LCD turns on, and you can begin measuring the tire pressure. The unit will turn off automatically to save power. If you need to measure tread depth, with the unit on, just push the power button once, and it will toggle to the tread depth mode. Slide the side metal ruler out and insert the tip into the groove of the tire tread. Now push down until the tire gauge touches the top of the tread, and the display will show in mm or inch for the remaining tread you have. There is also a red, yellow, green bar at the bottom to give you indication if you need to replace the tire. The tool is very handy and you can watch the full video review below.
