tire wear bar

I did a penny test on the tire. Tire thread is at middle of the Lincoln's hair. The "wear bar" on the tire is not yet flush with the thread. Does the tire need to be replaced?

If the tread is equal with or not touching the top of Lincoln's head then you should consider new tires. The distance between the edge of a penny to the top of Lincoln's head is about 3/32 of an inch, the minimum legal limit for tread depth is 2/32. However, tires worn to this point can be a safety concern. It is best to consider new tires once the tread depth is approaching 3/32 of an inch, or when the tread is just slightly overlapping with the top of Lincoln's head on the penny.

From this site...Checking Tire Wear - Wikiautos

You can also buy a tread depth gauge at most any auto parts store pretty cheaply.
