How to Read Tire Markings?
2 Answers
Common methods include observing the tire brand, tire specifications, load index, and speed rating. Below is a detailed introduction to car tire markings: 1. Importance: Tires are one of the most critical components of a vehicle, affecting driving safety, comfort, fuel efficiency, and more. Understanding each marking on the tire can help avoid accidents caused by tire issues. 2. Three T Marks: The three T marks, located on the sidewall of the tire, refer to Treadwear, Traction, and Temperature. They indicate the wear resistance, traction performance, and temperature resistance, respectively. The three T marks are commonly used tire markings.
As a novice driver, I was initially confused by the markings on tires, but gradually learned to understand them. The key is to focus on several critical parts: for example, size markings like 205/55 R16, where 205 indicates the tread width in millimeters, 55 is the aspect ratio (55%), R stands for radial construction, and 16 is the wheel diameter in inches. Additionally, the markings include speed symbols like V (maximum 240 km/h) and load indexes like 91 (carrying capacity of 615 kg), both of which affect driving safety. When changing tires, I always check the production date code, such as 4023, meaning the tire was manufactured in the 40th week of 2023. Tires older than six years should be replaced. Seasonal tires also differ, with winter tires featuring a snowflake icon and summer tires lacking it. Remembering these details makes it easier to match tire specifications to your vehicle, avoiding unstable handling or increased fuel consumption, and ensuring smooth daily driving.
