What are the tire tread standards in the 2021 new vehicle inspection regulations?

The 2021 new vehicle inspection regulations for tire treads require the use of a tire tread depth gauge. If the tire is severely worn and the depth does not meet the standards, the vehicle will not pass the annual inspection. Below are the relevant details: 1. New axle length inspection: The main purpose of this new inspection is to strictly investigate illegal modifications such as extending the axle length and other chassis alterations. Vehicles undergo safety inspections when they leave the factory, and any unauthorized modifications by the owner may affect the vehicle's safety. 2. New vehicle lifting device inspection: The lifting device inspection primarily examines the safety of the vehicle by checking areas such as the engine hood, trunk lid, and window lifting mechanisms.
Speaking of the new 2021 vehicle inspection regulations regarding tire tread standards, I've been in this line of work for years, and experience tells me it mainly comes down to tread depth and uniformity. The new rules require tread depth to be no less than 1.6 millimeters—just measure it with a dedicated tool, and you'll know right away. If it's too shallow, the grip is poor, making it prone to skidding in rainy conditions and causing accidents. The regulations also stipulate that tread wear must be even; you can't have one side worn smooth while the other side is still new—that's called uneven wear, commonly seen in vehicles that haven't had timely wheel alignments. Additionally, check for cracks, bulges, or cuts. These minor issues may seem insignificant, but a blowout at high speed can be deadly. I think the new rules are stricter than the old standards to reduce accident rates and remind everyone to maintain their vehicles regularly. I've seen many owners try to save money by not replacing tires, only to fail the inspection and waste money in vain. For a DIY check, use a one-yuan coin monthly to measure the tread—if the outer ring is visible, replace the tire immediately.
