For example, for a tire with the size of /55R17 99H. P/ 55 R16 89H - Aspect Ratio The aspect ratio tells you the height of the sidewall. It is expressed as a percentage of the tire's width. So, in this case. Our sample tire size has an aspect ratio of 55, which means that the sidewall height is 55% of the width. TIRE CONSTRUCTION. After the aspect ratio, you will. The first number indicates load carrying capacity if the tire is installed on a truck with a single-wheel rear axle, and the second number applies when the. There is a recommended rim width range for any given tire size with the ideal width usually around the middle of that spread. Some things to consider are how. The letter C stands for inner diameter, in this case mm. The French standard does not apply to all available tires. If you are picking out tires for your.

R – This indicates the tire construction (“R” means. 55 is the two-figure aspect ratio. This percentage compares the tires section height with the tires section width. For example, this aspect ratio of 55 means. What does R mean on tires? After the aspect ratio in this example, P/45R17 91V, you can find the letter R which indicates that the tire is a radial tire.
The ETRTO size designation (e.g. ) indicates the width (37 mm) and the inner diameter of the tire ( mm). This designation is unambiguous and allows a. What the Numbers in Tire Sizes Mean · = Section Width, or Tread (mm) · 55 = Aspect Ratio · 17 = Wheel Diameter · 97 = Load Index. /55R17 99H- The load index (99) is the tire size's assigned numerical value used to compare relative load carrying capabilities. The higher the tire's. 55 is the aspect ratio, so this means the height is equal to 55% of the tire's width. R stands for radial construction which refers to how the tires are made. What do tire sizes mean, and how do you read them? What are tire load index These numbers are necessary to get right when looking for tires, as a P/55R
