Tire Size Meaning There are two ways that tire manufacturers display tire size, inches and metric. To find the tire size meaning in inches is very straight forward. Example A : 33X12.50R15 The first number is your overall diameter of the tire. In this example the tire diameter or "height" is 33 inches tall.
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.
Diameter : 35 The Diameter of this tire size is 35 inches. The first number in a high flotation tire size is the overall diameter of the tire. Section Width : 12.50 The width of this tire size is 12.5 inches. The second number in a high flotation tire size is the width of the tire in inches. Tire Construction : R
Tire Size Guide: How to Read Tire Numbers and Letters Tire Class. The tire class is indicated at the beginning of the tire code. Typically, you'll see the letters P, LT, or Tire Width. The three-digit number following the tire class is the tire width. The width is the distance of the tire
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 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 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
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.
What Do the Numbers on a Tire's Size Mean? People often ask, "What do the numbers in a tire's size mean?" A friend of mine recently placed the following post on her Facebook wall: "Need some automotive help here. Will P225/60R16 tires fit a car that right now is 'wearing' LT215/70R16 tires?" The answers she got were as varied as could be.
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
The most basic information that you'll find on a tire's sidewall is related to its size. This is normally written as 185/65R15, for example, though you'll sometimes see "P" (for passenger cars)
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.

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. Specialized vehicles may use other markings such as JJ, K, JK, B, P, A, D, S, T, or W.
