What does it mean if your car's tires are “bald” under Pennsylvania law?

If a car's tires are described as "bald" under Pennsylvania law, it means that they have worn down to the wear bars, rendering them unsafe for driving. The term "bald tires" typically refers to tires that have lost significant tread depth due to wear, which can negatively impact traction, handling, and the vehicle's overall safety, especially in wet or slippery conditions. Pennsylvania law recognizes that tires must maintain adequate tread depth to ensure safe operation of a vehicle on public roads.

The use of wear bars is crucial since they indicate when the tread has worn down to an unsafe level. When the tread has worn down to meet these bars, it suggests that the tires are no longer able to provide sufficient grip, which could lead to a higher risk of accidents. Therefore, option B accurately reflects the legal and safety implications associated with bald tires in Pennsylvania.
