How to Read Tire Specifications and Models?

Tire specification and model dimensions are expressed in millimeters, representing the section width and the percentage of the aspect ratio. Followed by: tire type code, rim diameter (in inches), load index (allowable load capacity code), and allowable speed code.

I've been driving for over a decade, and reading tire specifications is quite straightforward. There's a combination of numbers and letters on the sidewall of the tire, like 205/55R16. The 205 refers to the tire width in millimeters, 55 is the aspect ratio percentage, R stands for radial tire construction, and 16 is the wheel diameter in inches. Following that, there's 91H, where 91 is the load index, and H indicates a maximum speed rating of 210 kilometers per hour. When replacing tires, it's crucial to match the original specifications—don't just opt for cheaper options to save money. I often check tire wear and pressure while washing the car to ensure the tread depth is sufficient for water drainage and anti-skid performance. These codes directly affect handling and fuel consumption, so safety comes first. I recommend regularly checking the tire manufacturing date to avoid driving on aged tires that could cause problems.
