What is the minimum tire tread depth required for a vehicle to pass inspection?

The minimum tire tread depth required for a vehicle to pass inspection is 2/32 of an inch. This standard is set to ensure adequate traction, particularly in wet conditions, which is crucial for safe vehicle operation. Tires with this level of tread depth are less likely to hydroplane and can maintain better grip on the road surface, helping prevent accidents.

While tires may still have some function at depths shallower than 2/32, they significantly increase the risk of losing control, especially during inclement weather. This is why regulatory bodies enforce this minimum depth; it represents a compromise between performance and safety, ensuring vehicles are equipped to handle normal driving conditions safely.

Higher tread depths, such as those reflected in other options, are generally preferred for optimal performance but are not mandatory for passing inspection.
