Motorcycle Tire Sizing: A Comprehensive Guide
Understanding Motorcycle Tire Size Notation
To determine the correct tire size for your motorcycle, it's essential to understand the metric and alpha size notation. The following table provides approximate conversions:
| Metric Size | Inch Size | Alpha Size |
| WM0 | 150 inches | - |
| WM1 | 160 inches | - |
| WM2 | 185 inches | - |
| WM3 | 210 inches | - |
Factors Determining Motorcycle Tire Size
There are five main aspects to consider when determining the ideal motorcycle tire size: 1.
Tire Diameter: The diameter of the tire is measured from one sidewall to the opposite sidewall. 2.
Rim Diameter: The diameter of the rim that the tire will be mounted on. 3.
Aspect Ratio: The aspect ratio is the ratio of the tire's height to its width. 4.
Section Width: The width of the tire's tread from one sidewall to the other.
Calculating Motorcycle Tire Size
The formula for calculating the overall motorcycle tire size is as follows:
Tire Diameter = (2 x Aspect Ratio x Section Width) + Rim Diameter For example, a tire with a 170/60/R17 designation would have the following measurements: * Section Width: 170 mm * Aspect Ratio: 60% * Rim Diameter: 17 inches Using the formula, we can calculate the tire diameter: Tire Diameter = (2 x 0.60 x 170) + 17 = 254 mm
Conclusion
Understanding motorcycle tire sizing is crucial for selecting the appropriate tires for your bike. By considering the metric and alpha size notations, as well as the five main factors that determine tire size, you can ensure that your motorcycle is equipped with the optimal tires for safety, performance, and comfort.
