What are the requirements for tires during vehicle annual inspection?

[OLeonardo]

During the annual inspection of vehicles, the requirements for tires are that the same model, specification, and tread pattern should be installed on both sides of the same axle. The tire bolts and axle bolts should be complete and tightened; the tire specifications should match the motor vehicle product announcement and the motor vehicle factory certificate; the length of the tire tread and sidewall should not exceed 25mm or be too deep, as this can affect abnormal wear and deformation. Depending on the type and usage of the vehicle, dedicated school buses should use tubeless radial tires; highway buses, tourist buses, and school buses should have all wheels fitted with retreaded tires and should be sent for regular inspections; vehicles transporting dangerous goods and other buses with a length greater than 9m should use radial tires; for passenger cars, motorcycles, and trailers, the tread depth should be greater than or equal to 1.6mm, while the tread depth of the steering tires for other motor vehicles should be greater than or equal to 3.2mm; the tread depth of the remaining tires should be greater than or equal to 1.6mm. Tire maintenance methods: regularly clean stones from the tire treads; minimize exposure of tires to direct sunlight; promptly check tire pressure; pay attention to suspension maintenance; inspect front wheel alignment; be mindful of driving habits, choosing smooth roads to avoid objects that can puncture or scratch tires, and avoid chemical spills that can corrode tires. Steps for vehicle annual inspection: exhaust emission test, the first item in the annual inspection, which requires re-inspection if failed; violation check, if there are unresolved violations, the inspection cannot be passed; appearance inspection, mainly checking for damage to the vehicle body, tires, lamp covers, etc., and whether the owner has made unauthorized modifications to the vehicle; on-site testing, mainly checking brakes, lights, horn, chassis, etc.; review, after all tests are completed, the vehicle management office will review the indicators; certification, if the review is passed, the motor vehicle inspection certificate can be obtained.

I just had my annual vehicle inspection last year, so I'm quite familiar with the tire requirements. The main points are that the tread depth must not be less than 1.6mm, which is checked with a tread depth gauge; also, you need to look for bulges, cracks, or obvious damage on the tires—those small cracks can become very dangerous if they accumulate. The two tires on the same axle must be of the same specification; don't mix a summer tire with a winter tire. The tire pressure also needs to be adjusted to normal, as too high or too low can affect braking performance. Last year, my car's tires had minor cracks and were required to be replaced. For daily checks, it's recommended to use a coin to measure the tread—if the entire head of the coin is visible, it's time to replace the tire, so you don't have to deal with failing the inspection later. Regular tire maintenance can avoid a lot of trouble, especially for drivers who frequently drive on highways.

Bro, think about tire inspection requirements from a safety perspective. The tread depth must be at least 1.6mm for anti-slip purposes, ensuring stability when driving fast in the rain. Tires must not have bulges or large cracks, as they could blow out on the highway. Tire pressure must be standard—too high or too low will increase braking distance. Avoid mixing tire specifications on the same axle, as it affects handling. I learned the hard way when I failed inspection for not checking tread depth. It's advisable to measure the depth yourself before the inspection using an APP tool or a coin for assistance. Regularly rotating tire positions can extend their lifespan and ensure safer driving—don’t wait for an accident to regret it.

Annual inspection tire regulations in brief: tread depth must not be less than 1.6mm; no bulges, cracks, or significant damage; tires on the same axle must be of the same type; proper tire pressure. These are strict requirements to ensure road safety. During inspection, technicians will measure with tools - non-compliance means failure. Don't neglect regular maintenance, always keep a tire pressure gauge handy.
