How can I tell when a tire is bald?

Answer by  Mable (3008)

The old test is to put a penny in the tread and see where it comes on Lincoln. Better accuracy is to check the tire's instructions: most have a colored thread woven in that appears when the tread is too worn. Or, you can take your vehicle for inspection -- it won't pass without sufficient tread on the tires.

Visually inspecting a tire can conclude if it is bald. You can typically see the tire treads without having to use a gauge. If the tread is still visible you will want to use a gauge to measure the depth of the tread. You can also use a penny to gauge the thickness of the remaining tread on a tire.
