What is the minimum tread depth for passenger vehicles in Maine?

The requirement for a minimum tread depth of 2/32 of an inch for passenger vehicles in Maine is crucial for ensuring adequate tire performance and safety. Tires are designed to provide traction, especially in wet conditions, and maintaining the appropriate tread depth is essential for effective water displacement and grip on the road. When the tread depth falls below this minimum, the tires may become less effective at preventing hydroplaning and may lead to longer stopping distances. By setting the minimum tread depth at 2/32 of an inch, Maine regulations help to ensure that vehicles maintain a level of safety that protects both the driver and others on the road.
