tread depth
Groove thickness remaining
Tread depth is the measurement of the grooves in a tire, indicating how much usable rubber remains.
New tires typically have 10/32 to 11/32 of an inch; at 2/32, tires are legally worn out in most jurisdictions.
The penny test—inserting a coin to see if Lincoln's head is visible—offers a rough gauge.
Adequate tread depth is essential for grip, especially on wet roads.
