Bald tires are such used tires which have almost no tread. As you know that tread is such an important factor that helps tires to keep grip on the road, so bald tires can be extremely dangerous for driving. For maximum safety, tires should be replaced before they are actually bald. Every year, bald tires became the cause of hundreds of accidents.

Generally, tires are able to use until its tread depth arrives 1/16 of an inch (which is equal to 0.15 cm). In the United States, consumers use a penny to check the safety of tire. It is a common rule that people insert a penny between the treads of the tire. The Lincoln’s head portion of the penny points down. If you see the top section of Lincoln’s head then it is the clear signal that replace the tire. Penny coins in many other different countries can be used in the same way according to their rules. Most tire manufacturers also pressed tread wear indicators, which will become visible when a tire needs to be replaced.

Bald tires are dangerous for many reasons. Limited tread of bald tires reduces traction for the vehicle, which can be very harmful when you drive in icy or wet conditions. Since they are stressed, the chances of failing increases more, especially at high speed. So, the United States Department of Transportation suggests that either vehicles have new or used tires, drivers should check them properly on monthly basis and when they are going for a long trip then first ensure that the tire tread depth is safe.
