It is indicated by a letter of the alphabet, which refers to a table that is common to all manufacturers. Each letter corresponds to a certain maximum speed. It starts from letter "A", the only one which is broken down with numbers (A1, A2, A3, etc.) and which allows speeds of between 5 to 40 km/h.
The section width is the width of the tire from one sidewall to the other measured in millimeters. In this example, the tire is 245 millimeters wide. 45 =Aspect Ratio (Ratio of Sidewall height to width) The aspect ratio refers to the height of the sidewall, and it is a percentage of the section width.
Tire size can be defined as a collection of numbers and letters that describe tire type, width, sidewall height, and wheel diameter — alongside other information. An example of a common tire size is as follows: P225/65R17. The tire size for your vehicle and wheels can be found in two places: The sidewall of your tire. Is the width of the tire measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P215/65 R15 tire, the width is 215 millimeters. Aspect Ratio Is the ratio of the height of the tire's cross-section to its width. The number 185 is the tire's width in millimeters, from one sidewall to the other. The number 60 after the forward slash character means the tire's height from rim to tread is 60 percent of its width, which again is 185 millimeters. R14 means the tire is meant to fit on a 14-in. diameter wheel.
Tire Width The tire width is measured from sidewall to sidewall of the tire. It is represented by a three digit number and measured in millimeters. In our example above, the width is 185mm. Aspect Ratio Aspect ratio is the ratio of the height of the tire's cross-section to its width.
A tire's aspect ratio is its height to width in percentage. A tire with 205 mm width and 55 mm sidewall height has a 55% aspect ratio. Aspect ratio impacts tire diameter. The first number in a tire size is the width in millimeters, and the second represents the aspect ratio. Tire Size Meanings A: TIRE TYPE. The first letter in the code tells you what class of tire it is. P stands for passenger vehicle tire. B: TIRE WIDTH. The three-digit number following the letter is the tire's width (from side to side, looking at the tire C: ASPECT RATIO. The forward slash

The aspect ratio, or profile, refers to the height of the sidewall as a % of the section width. In our example, 55 means the height is equal to 55% of the 195mm width. The bigger the aspect ratio, the bigger the sidewall will be.
