[IrisDella]

There are four main requirements for tires in the 2020 vehicle inspection, detailed as follows: 1. Installation: Tires of the same model, specification, and tread pattern should be installed on both sides of the same axle. Tire bolts and axle bolts should be complete and securely fastened. The tire specifications should match the motor vehicle product announcement and the motor vehicle factory certificate (for in-use vehicle inspections, it should match the motor vehicle registration information). 2. Damage: The tire tread and sidewall should not have cracks or cuts exceeding 25mm in length or deep enough to expose the tire cord layer, nor any other defects, abnormal wear, or deformations that affect usage. 3. Passenger cars, motorcycles, and trailers: The tread depth of the tire crown should be no less than 1.6mm. For other motor vehicles, the tread depth of the steering wheel tire crown should be no less than 3.2mm; the tread depth of the remaining tires should be no less than 1.6mm. 4. Highway buses, tourist buses, and school buses: All wheels and the steering wheels of other motor vehicles should not be fitted with retreaded tires.
