Replacing tires that meet the standards can pass the annual inspection. Vehicle Annual Inspection: Vehicle annual inspection refers to the annual examination of vehicles that have already obtained official license plates and registration certificates, conducted in accordance with the "Technical Conditions for Motor Vehicle Operation Safety." The purpose is to check the main technical conditions of the vehicle, urge the strengthening of vehicle , keep the vehicle in good condition, and ensure driving safety. Inspection Frequency: For passenger transport vehicles, the inspection is conducted once a year within the first 5 years. After 5 years, it is conducted every 6 months. For cargo vehicles and large or medium-sized non-passenger transport vehicles, the inspection is conducted once a year within the first 10 years. After 10 years, it is conducted every 6 months. The annual inspection of motor vehicles is divided into the initial annual inspection and regular annual inspection.

















Last time I also got new tires before the annual inspection, and there was no problem at all. The inspection mainly checks if the tire specifications match the original factory settings—you can't randomly increase the size or width, or it will be considered illegal modification and fail. The tread depth must be sufficient, with a minimum of 1.6mm, which they measure with a gauge. They also require that the two tires on the same axle must be identical—you can't have a performance tire on the left and a regular tire on the right, as it would cause braking imbalance. Once, my neighbor went for the inspection with winter tires, and the inspector checked for cracks or bulges on the tread—his passed safely. It's recommended to keep the original tire parameter documents when replacing tires, as they might be useful during the inspection.

With over a decade of experience in auto repair, I've seen it all – changing tires to pass inspections is a sure bet. Just remember two non-negotiable standards: First, the size specifications must exactly match those on the vehicle registration certificate. For example, swapping 18-inch rims for 19-inch ones is a violation. Second, tread depth is crucial – I've seen cases where tires worn down after 80,000 kilometers went unnoticed by the owner, only to be slapped with a rejection sticker at the inspection station. Another often-overlooked summer issue is the tire pressure monitoring system, now standard in new cars. Damaging the sensors during tire replacement will definitely result in a failed inspection. My advice? Stick with the same brand and model when replacing tires. Don't cut corners with used or retreaded tires – inspection station staff have sharp eyes for these things.

Last week, I accompanied my friend to the DMV, and his passed the inspection smoothly after getting new tires. The inspection process is actually just three steps: first, check if the tire size matches the original factory specifications on the nameplate; second, inspect the tire surface for any cuts or bulges; and finally, measure the tread depth. Remember, the tread patterns on all four tires must be consistent—don’t mix a drainage-pattern tire on the left front with a slick tire on the right front, as that will definitely get you flagged. My friend bought his tires from Tuhu Auto Service for 180 yuan each, saving half compared to the dealership. It’s also a good idea to check and inflate the spare tire beforehand, as they sometimes inspect that too.

As an experienced driver of thirty years, I've got some insights on changing tires for annual inspections. Don't believe those who say it's not allowed – the key is doing it properly. Last year, I replaced all the old tires on my and made sure the shop kept the original 185/65R15 size specification sheet. During the inspection, they checked the size against the sheet and had me turn the steering wheel left and right to observe tire movement. They also used a small device to check the tire manufacturing date – tires over six years old are recommended for replacement even if they show no wear. Once on a rainy day, I saw an inspector lying on the ground feeling the tread grooves, so it's important to regularly remove stones and mud buildup.

Last time before my annual inspection, I changed to Michelin quiet tires and passed in one go. The inspector focused on three key areas: first, the production date marking on the outer side of the tire, which must not exceed 6 years; second, the tread depth—insert a coin into the groove, and if the exposed part is less than 1.6mm, it's qualified; third, checking for any signs of wheel modification. Interestingly, they had me start the car and press the brake while they shone a flashlight to check the gap between the brake pads and the tire. I recommend avoiding the rainy season for the inspection, as mud can easily obscure the production date code. The original tire specifications can be found on the label inside the door frame—just follow that for replacements, and you can't go wrong.
