Where is the tire quality certification agency?

Find the tire manufacturer and have them conduct the certification. If it is not a quality issue, request the manufacturer to issue a legally valid quality certification document; with this certification document, you can then go to Zhongke Testing, whose issued certificates are authoritative; third-party agencies that certify tire quality. The current state of testing in China: Domestic products are tested by national testing agencies, such as the Quality Supervision Bureau and the Disease Control Center, while exports are mainly handled by foreign testing agencies. Domestic third-party testing agencies are struggling to survive in the gaps. Tire size classification: A full-size spare tire has the exact same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. A non-full-size spare tire has a slightly smaller diameter and width than the other four tires, so it can only be used as a temporary substitute and must be placed on a non-drive wheel, with a maximum speed not exceeding 80km/h.
I commute by car daily, and when encountering tire issues, I always think about finding a reliable place for inspection to avoid accidents. The most hassle-free method is to visit the 4S shop or tire specialty store near home—they usually have testing equipment to check for tire wear, aging, or abnormal pressure. If you feel these shops aren’t authoritative enough, search online for labs or certification centers under China’s General Administration of Quality Supervision, such as the China Quality Certification Center (CQC). They specialize in this, but ordinary people may need to fill out a pile of forms to request testing. By the way, third-party institutions like SGS also operate in China, offering professional evaluation reports. I recommend regular tire health checks to avoid breakdowns that could compromise safety. Also, avoid overloading when driving—excessive tire wear makes inspections more troublesome. Safety is no small matter; spending a bit for peace of mind is worth it.
I'm a car enthusiast who spends my spare time researching tire technology. To assess quality, you need to find professional institutions, such as internationally recognized DOT or ISO agencies. In China, you can consult testing sites recommended by automotive industry associations. During specific operations, they use machines to test indicators like grip, pressure resistance, and noise levels to ensure tires meet standards before leaving the factory. Ordinary people don't need to visit labs in person; just check the official websites of companies like TUV Rheinland to book an appointment—affordable prices and accurate reports. I've found that checking certification marks before buying tires is very convenient, whether it's the U.S. DOT or European ECE standards. Additionally, real-world tests shared by fellow car enthusiasts on automotive forums can also serve as references to avoid low-quality products. Make it a habit to perform simple self-checks every six months, like checking if the tread depth is below 1.6 millimeters, which should raise an alert.
