When picking up a new car, it is essential to conduct a comprehensive inspection of the vehicle. First and foremost, pay attention to a set of numbers on the outer sidewall of the tires, which indicate the manufacturing date of the tires. Generally, the time from production to warehousing for tires should not exceed 3 years, and the usage time should not exceed 8 years. Tires have markings on them. For retreaded tires, these markings are usually stickers that can be rubbed off with a finger, whereas the markings on new tires cannot be rubbed off. Carefully inspect the tires for any scratches or wear. If the vehicle has been driven, the wear on the tires will be quite noticeable.

As someone who frequently works on cars, I know identifying original tires isn't that difficult. The key is to check the markings on the tire sidewall: OEM tires often have a special OEM code, which is a unique serial number that can be matched in the vehicle manual. The brand should also be correct, like Bridgestone tires for a Toyota. Additionally, details such as the size (e.g., 215/55R17) and speed rating (e.g., H) should match the factory specifications. I also pay attention to the tire's production date code, usually a four-digit number indicating the week and year, ensuring the tires are of the same age. OEM tires are specifically designed for the vehicle, offering better grip and fuel efficiency, so I regularly check for even wear. If unsure, you can visit a dealership to verify the vehicle records. After all, maintaining original parts enhances handling safety and provides peace of mind on long trips.

When I first bought a car, I was also curious about how to confirm if the tires were original. The direct method is to check the vehicle manual for tire specifications: the tire width, aspect ratio, and wheel size are all clearly listed. Then, look for any brand-specific markings on the tires, like Honda vehicles might have tires with the Honda logo. The production date code is prominently placed, with the last two digits indicating the year and the first two digits the week number, ensuring the tires are new. If they've been replaced, the tire brand and model might differ, but I recommend sticking to the original specifications for reliability, avoiding issues like excessive noise or instability. Checking the model online or using a mobile app for comparison is also convenient.

Identifying original tires involves several key points. Check if the sidewall information matches the vehicle: specifications like 205/50R16 and speed symbol T can be found in the manual. Original tires often have unique OEM codes printed on the side. The brand should also be a partner of the car manufacturer, such as Goodyear for General Motors. Don't overlook the production date code, a four-digit number indicating the manufacturing time. The simplest way is to ensure the tires look neat and uniform, with new tires having deep and even tread patterns.
