Review on 📏 PROND Tire Tread Depth Gauge - Accurate Measurement Tool for Tire Tread Depth, Color Coded Gauge for Tire Depth, Tire Tread Gauge - White Type by Joshua Pilla

Bought this to keep an eye on my wife's tires as they were nearing the end of their tread life. This works well to let you know how low your profile is getting. The displays are a bit small and difficult to read in low light, but that's not a bother. The measurements match what the tire shop gave me after measuring the tread, so I'm sure they're accurate. Not sure about durability but they are cheap enough to replace as I monitor tread life on two other cars.
