Motorcycle Tyre Conversion Chart Imperial To Metric
As a motorcycle enthusiast, you may be familiar with the different measurements used to identify the size of your motorcycle tyres. Some motorcycle tyres are measured in imperial units, while others are measured in metric units. Unfortunately, this can create confusion when you need to purchase new tyres or replace your existing ones. To help you understand the differences between imperial and metric tyre sizes, this article will provide a comprehensive motorcycle tyre conversion chart.
What are Imperial Units?
Imperial units are a system of measurement that were adopted in the United Kingdom in the 19th century. These units include measurements such as inches, feet, and pounds. In the context of motorcycle tyres, imperial units are used to measure the diameter, width, and aspect ratio of the tyre.
What are Metric Units?
Metric units are a more modern system of measurement that are used in most countries around the world. These units include measurements such as millimeters, centimeters, and kilograms. In the context of motorcycle tyres, metric units are used to measure the diameter, width, and aspect ratio of the tyre.
Why Convert from Imperial to Metric Units?
If you have a motorcycle that was manufactured in the United States, it is likely that the tyre size is measured in imperial units. However, if you are purchasing a new tyre or replacing an existing one, you may find that the tyre you need is only available in metric sizes. In this case, you will need to convert the imperial measurements to metric measurements in order to find a compatible tyre.
