Changing the size of the car's rims requires registration, but if the rim size remains unchanged, registration is not necessary. Here are the relevant details: 1. Before modification, you can consult the vehicle management office to understand the situation. Otherwise, it may fail the annual inspection and you may be ordered to restore the original condition. If you replace the rims with the same size, the annual inspection can generally be passed, but the appearance should not change too much unless local policies are very strict. 2. According to Article 6 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," changes such as body color, engine replacement, frame replacement, substandard body quality, illegal operation, and household registration changes must be reported. Other small, legally produced parts that do not affect performance do not need to be reported. As long as the size of the replaced rims is the same as the original, the appearance can be changed freely. If the size is changed, it will not pass the annual inspection.

I've driven cars for hundreds of thousands of kilometers and changed wheels several times. Whether you need to register wheel modifications mainly depends on whether the specifications match the original factory settings. If the size and shape remain unchanged, and you're just changing the color or style, generally no registration is required—you can swap them yourself. However, if you increase the wheel size, such as changing from 17 inches to 19 inches, you must register the modification with the vehicle management office, as regulations require reporting changes to key vehicle structures. The registration process is straightforward: bring your vehicle license, ID card, take photos of the modified car for review, pay a small fee (usually around a few dozen yuan), and it's typically done the same day. If you don't register, you risk being fined or penalized if caught by police or involved in an accident, and insurance companies may deny claims. Safety is also a major concern—larger wheels can affect braking and stability, and registration helps you avoid these risks. Before modifying, check your local vehicle management office's rules—don't skip the process to save trouble.

I have a modified car and love upgrading my wheels. If you're just replacing wheels with the same size and specifications, usually no one cares about registration. I've changed to colored ones before without registering. But if you go up an inch or more, like from 18-inch to 20-inch, you must register it to be safe. Last time, my friend got stopped by traffic police for not registering—got a lecture, a fine, and his car was thoroughly inspected. Registration isn't hard: just fill out a form at the DMV, get your car photographed and checked, and it costs less than 100 yuan, taking less than half a day. After modification, the handling changes—bigger wheels raise the car, making it easier to skid in rain. Test drive to check balance before committing. It's great to personalize your car, but remember not to cross legal boundaries.

Years of car repair experience have taught me that safety is the top priority when modifying rims. If the new rims match the original factory size, no registration is required; however, any changes in size or shape, such as upsizing or widening, must be registered. The reason is simple: unregistered illegal modifications can lead to insurance claim denials in case of accidents and result in penalty points for violating the law. Changing rim specifications may cause tire rubbing or suspension damage, posing risks during high-speed driving. The registration process only requires submitting an application at the vehicle management office, followed by an on-site inspection to update the vehicle registration certificate. It's advisable to have a professional shop test compatibility before making changes to avoid major losses for minor gains.
