Where to Find Tire Size Specifications?
3 Answers
The tire size specifications are printed on the sidewall of the tire. For example, 205/55R16 indicates a tread width of 205 millimeters, an aspect ratio of 55, and compatibility with 16-inch rims. The aspect ratio is straightforward to understand: 55 means the sidewall height is 55% of the tread width. The sidewall is the part between the rim and the ground when viewed from the side. A higher aspect ratio means a thicker sidewall, which increases the distance between the rim and the ground. Here's an explanation of the numbers and letters in a tire model, using 225/60R17 99H as an example: 1. 225: Represents the section width, simply the width of the tire tread. 2. 60: Represents the aspect ratio, indicating the height of the tire sidewall. 3. R: Stands for the tire type code, with R denoting a radial tire. 4. 17: Indicates the rim diameter, meaning the tire fits a 17-inch rim. 5. 99: Represents the load index, the maximum weight the tire can bear. 99 corresponds to a maximum load of 775 kg. 6. H: Indicates the speed rating, the maximum speed the tire can handle. H means the tire can withstand speeds up to 210 km/h.
I remember checking the tire specifications when I first bought the car. Those numbers engraved on the sidewall are the model numbers, located near the rim with clear and visible text. For example, seeing '205/55 R16' means 205 refers to the tire width of 205 millimeters, 55 is the aspect ratio, and R16 indicates a rim diameter of 16 inches. The sticker on the door frame is also a common place to find this information, or you can check the trunk page in the owner's manual. Never neglect regular tire inspections to prevent skidding accidents caused by worn treads. Make it a habit to glance at them every month—don’t slack off.
As a mom who drives my kids around, I'm used to checking the label on the door frame for tire specifications. It's located right by the driver's door, and the label clearly lists all the size information. The tire sidewall also has a series of characters printed on it, like '195/65 R15'—just snap a photo with your phone to remember. If the label is worn or illegible, refer to the owner's manual; it contains diagrams with explanations. A quick reminder: when getting new tires, make sure the model matches, or it might affect handling and safety.
