How to Read Tire Size Specifications?
1 Answers
Tire specifications are labeled on the sidewall in the order of "tire width, aspect ratio, rim diameter, load index, and speed rating." Here is the relevant information: 1. If the tire specification is 195/55/R15-85V, it means the tire width is 195mm, the aspect ratio (section height to width) is 55%, it is a radial tire (R) suitable for a 15-inch rim diameter, the load index of 85 represents a maximum load capacity of 515 kg, and the speed rating is 240 km/h. 2. Tire width is one of the factors affecting a vehicle's fuel consumption. The wider the tread, the larger the contact area with the ground, resulting in greater friction, and wider tires tend to consume more fuel. However, wider tires also provide stronger grip and better handling. Conversely, narrower tires have lower fuel consumption and a lighter driving feel, but with a smaller contact area with the ground, the grip is not as strong.
