The set of numbers straight after the tyre width refers to the thickness of the tyre wall (or aspect ratio), which is a percentage of the width. So, in this case, 55 would have a height equal to 55% of the tyre's width. This number is often referred to as the tyre profile. Tyre construction

What Do The Numbers On Tires Mean? Tire service type ratings. Most tire sizes begin with one or more letters -- for example, P or LT. The letter tells us P = P-Metric (Example: P215/65R17 98T).

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.

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.

P denotes passenger-car tire. Some may start with an LT prefix, used on heavy-duty trucks. The number 235 is the cross-section width in millimeters, and 65 is the ratio of sidewall height to J - On some wheels, the letter 'J' might appear next to the wheel width, such as 16x7J. The letter J lets you know the shape of the wheels, and how the tire beads align with the wheels. J is commonly used for most passenger vehicles.

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. 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. 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.
A "C" indicates 6 plies, a "D" indicates 8 plies, and an "E" indicates 10 plies. The higher the number of plies in a tire, the stronger the tire is and the more air pressure the tire can safely hold. Higher ply tires require more air pressure to maintain proper wear.
