Motorcycle Tyre Size Converter Imperial To Metric
As a motorcycle rider, it is important to have the right tyre size to ensure a smooth and safe ride. However, tyre sizes can be confusing, especially since some countries use imperial measurements while others use metric. This is where a motorcycle tyre size converter comes in handy.
Imperial Tyre Sizes
Imperial tyre sizes are measured in inches and are commonly used in the United States. The size is usually written as a series of numbers and letters, such as 120/70-17. The first number indicates the width of the tyre in millimetres, the second number is the aspect ratio (the height of the tyre sidewall as a percentage of the width), and the final number is the diameter of the wheel in inches.
For example, a tyre with a size of 120/70-17 means that the tyre is 120 millimetres wide, has an aspect ratio of 70%, and fits on a 17-inch wheel.
Metric Tyre Sizes
Metric tyre sizes are measured in millimetres and are commonly used in Europe and other parts of the world. The size is usually written as a series of numbers, such as 180/55R17. The first number indicates the width of the tyre in millimetres, the second number is the aspect ratio (the height of the tyre sidewall as a percentage of the width), and the final number is the diameter of the wheel in inches.
For example, a tyre with a size of 180/55R17 means that the tyre is 180 millimetres wide, has an aspect ratio of 55%, and fits on a 17-inch wheel. The "R" in the size indicates that it is a radial tyre.
Why Convert Tyre Sizes?
There are several reasons why you may need to convert tyre sizes. For example, if you are importing a motorcycle from Europe, it may have metric tyres that need to be replaced with imperial tyres to comply with US regulations. Alternatively, if you are traveling abroad with your motorcycle, you may need to convert your imperial tyres to metric to ensure that you can find replacements if needed.
Another reason why you may need to convert tyre sizes is if you are trying to upgrade your motorcycle's tyres. Many riders prefer to use tyres with different sizes to improve handling, traction, and overall performance. By using a tyre size converter, you can easily compare the size of different tyres and choose the one that best suits your needs.
Using a Tyre Size Converter
There are several online tyre size converters that you can use to convert between imperial and metric tyre sizes. These converters are usually free and easy to use. Simply enter the size of your current tyre and the converter will provide you with the equivalent size in the other measurement system.
It is important to note that tyre size converters are not always 100% accurate. This is because different tyre manufacturers may have slightly different sizes for the same tyre. It is always a good idea to double-check the size of the tyre before making a purchase.
Conclusion
Motorcycle tyre sizes can be confusing, especially since there are different measurement systems used around the world. However, with the help of a tyre size converter, you can easily convert between imperial and metric tyre sizes and find the right tyre for your motorcycle.
