It is called a "tread depth measurement"
There is a special tool for this or you can use a caliper set that will do depth measurement or a "Machinist rule"
A very easy test is to take a Lincoln penny and insert it between the treads head down. If you can see the top of lincoln's head your tires need replacing. This means the tread is worn to below 2/32" which is the danger level. The tires have very little grip and are prone to hydroplaning when worn this much.

How can I know if my car's tires are worn out?
Always check for visable damage to the tire itself. If there is no visible damage, the easiest way to check tire wear is the penny test. Place a penny "head down" into the groove of a tire, If you can see the top of it's head, your tires need replace, legally. However, you should replace your tire when the tread is reduced below 4/32 of a inch. The easiest way to measure this is actually to us the "Quarter test". Do this test the same as the penny test on with a quarter, for a more accurate reading or check your tires "wear bars" which are bars within your tread that are below the tread and are the minimum safe depth for your tire.
