Question: 1 / 400

What is a key sign of tire wear that should be checked during inspections?

Tread depth

Tread depth is a vital aspect of tire wear that should be meticulously checked during vehicle inspections because it directly affects traction, handling, and safety. Tires must have sufficient tread to provide grip on various road surfaces, especially in wet or slippery conditions. Insufficient tread depth can lead to hydroplaning, increased stopping distances, and diminished control, which elevates the risk of accidents.

Regularly checking tread depth ensures that tires meet legal requirements and are safe for use on the road. Using tools like a tread depth gauge or the penny test can help determine if the tires are worn beyond acceptable limits and in need of replacement. Ensuring proper tread depth is an essential part of routine vehicle maintenance and enhances overall road safety.
