Goodyear Tire Specifications?

Goodyear/GoodYEAR EfficientGrip 225/50R17 94V. Below is an introduction to Goodyear tires: 1. Quality: High durability, long service life, excellent grip, outstanding economy, hailed as the quietest and most comfortable tire ever. It utilizes the latest noise-reduction technology, featuring a closed shoulder design that effectively blocks sound wave transmission to minimize noise. The uniform tread block design ensures gentler contact with the ground, reducing noise generated upon contact. The vertical garden design effectively prevents uneven long-term wear and noise caused by wear. 2. Function: Supports the full weight of the vehicle, withstands the vehicle load, transmits forces and moments in other directions, delivers traction and braking torque, and ensures good adhesion between the wheel and the road surface.
When I used to choose Goodyear tires, I paid special attention to the series of numbers on the sidewall. For example, in the common "245/45 R18 100W" marking, the first three digits 245 indicate the tread width is 245 millimeters, and 45 represents that the sidewall height is 45% of the tread width, known as the aspect ratio. The R stands for radial construction, which is pretty much standard these days. The 18 means it fits an 18-inch wheel. The following number 100 is the load index, which translates to a maximum load capacity of 800 kilograms, and the letter W indicates a top speed rating of 270 km/h. For long-distance driving, it's essential to check if the load index is sufficient, while for track use, the speed rating is more critical. Nowadays, some new tires also feature the MOE symbol, which signifies Mercedes Original Equipment certification.
Goodyear specifications are like clothing sizes; they must match the vehicle. My neighbor once installed the wrong size and nearly had an accident. For example, the Efficient Grip series offers multiple options like 205/55R16 and 225/50R17, where 55 and 50 represent the aspect ratio. Forcing low-profile tires onto older models can lead to sidewall bulges when driving over speed bumps. For winter, it's best to purchase snow tires according to the original factory specifications, with studded tires bearing special markings. The newly released EV tires even feature an "EV" logo, with reinforced sidewalls to withstand electric motor torque.
You can tell the tire specifications by looking at the sidewall characters. Taking the Goodyear Assurance as an example, in the common size 215/60R16, the '60' represents the aspect ratio—the larger the number, the thicker the sidewall and the better the comfort. In the last two digits '91V', '91' indicates a load capacity of 615kg, and 'V' stands for a maximum speed of 240km/h. When replacing tires, ensure the new tires match the old ones in specifications, or they won't pass the annual inspection. For four-wheel-drive vehicles, it's especially important that all four tires are of the same specification; even a half-centimeter difference can damage the differential.
Goodyear tire specifications involve three key numbers. The tire width affects grip and fuel consumption; my actual test showed that 225-width tires consume 0.5 liters more fuel per 100 km compared to 205-width tires. The middle two digits, such as the 40 aspect ratio on Eagle F1, indicate that a smaller number makes the tire more prone to blowouts but offers more precise handling. The final letter represents the speed rating, with H-rated tires (210 km/h) being sufficient for most SUVs. When changing tires, always check the vehicle's nameplate data, as incorrect specifications may cause the tires to rub against the wheel arches when turning.
