Metric tire designations: The width is expressed in milimeters. The aspect ratio is expressed as a percentage of the width and defines the distance from the outer edge of the tire to the edge of the rim. The rim size is expressed in inches. Standard tire designations: These are straightforward diameter, width and rim size expressed in inches. Two dimension designations: If your tire size is similar to this: "13.00-18", you'll need to look it up in our tire charts. This designation only provides two dimensions (width and rim size) and therefore does not provide enough information for the calculator. |
