How to Read Tire Markings

Understanding tire markings is essential for selecting the correct tires for your vehicle. These markings provide a wealth of information about the tire's size, load capacity, speed rating, and other important characteristics. The most prominent marking is the tire size, which is typically displayed as a combination of numbers and letters, such as 205/55R16. As mentioned earlier, the first number (205) indicates the tire's width in millimeters, the second number (55) is the aspect ratio, 'R' signifies radial construction, and the last number (16) is the rim diameter in inches.

In addition to the size, tires also have a load index and speed rating. The load index is a numerical code that corresponds to the maximum weight a tire can carry when properly inflated. This number is usually followed by a letter, which represents the speed rating. For example, a tire with a load index of 91 and a speed rating of V can carry a maximum load of 615 kg (1356 lbs) and is rated for speeds up to 240 km/h (149 mph). Always ensure that the tires you choose meet or exceed your vehicle's load and speed requirements.

Other important tire markings include the Department of Transportation (DOT) code, which indicates the tire's manufacturing date. The DOT code is a series of letters and numbers, with the last four digits representing the week and year the tire was manufactured. For example, a DOT code ending in '2023' indicates that the tire was made in the 20th week of 2023. It's advisable to purchase tires that are relatively new, as rubber compounds can degrade over time, even if the tires have not been used.

Tire markings also provide information about the tire's construction and materials. Markings such as 'M+S' indicate that the tire is designed for mud and snow conditions, while 'XL' signifies that the tire has an extra load capacity. Understanding these markings can help you make an informed decision and select tires that are best suited for your vehicle and driving conditions.
