Michelin Treadwear Indicator
Narrow bands, sometimes called wear bars, that appear across the tread of the tire when only 2/32 inch of tread remains.

Bridgestone Tire Warranty
The tire must not be worn to 2/32 inch (1.6 mm) or less remaining original tread depth (i.e. worn down to the top of the built-in indicators in the tread grooves).

Goodyear Tire Maintenance
Check the Tread Wear Indicator Bar: Located at the bottoms of the tread grooves in several locations around the tire. When a tire is so worn that these bars become visibly flush with the adjacent tread ribs, it’s time to replace the tire.
Or
Take the Penny Test: Simply insert a penny into your tire’s tread groove with Lincoln’s head upside down and facing you. If you can see all of Lincoln’s head, it’s time to replace your tires.
