Vehicle tires are designed with treading to help the rubber grip the road. However, they will wear down over time, which reduces the safety of the driver and passengers as well as the car's performance. Here are some details about treads that will help you recognize when it's time to invest in new or used tires.

A Guide to Tire Tread

What Are the Tread Depth Requirements?

Tread depth refers to the verticle measurement of the top surface of the tire from the bottom of its deepest grooves. The industry requirement for the United States is that the depth must exceed 2/32 inch. Most new tires measure at 10/32" or 12/32". At 2/32", a tire is deemed bald because it no longer produces the friction needed to grip the pavement firmly. Driving in this condition becomes especially treacherous in rain, sleet, or snow because the roadways are already slick with precipitation. 

To ensure your car tires meet the standard requirements, you should measure the tread depth regularly. You can use a tread depth gauge for an accurate reading, and you can find them in most tire shops. If you don't have one on hand, you can use a penny. Place the coin in tire groove so that Lincoln's head is downward. If the top of his head disappears, the tire has enough tread. If it's visible, it's time to purchase new or used tires. 

What Are the Common Wear Patterns?

Tires don't wear down into a universal pattern; the wear and tear can take on several forms. For instance, if the tires are over-inflated, the wear and tear will be evident down its middle. Conversely, under-inflation will cause the outer edges of the tire to go bald while tread remains in the center. Feathering is another wear pattern that indicates an excessive positive or negative tire alignment. This type of wear is scuffing, which makes one side of the tread pattern lower than the other.
