Motorcycle Tyre Size Conversion Inches To Metric
One of the most important parts of a motorcycle is the tires. They are responsible for providing grip, stability and safety while riding. Choosing the right size tire for your motorcycle is crucial. The size of a tire is usually measured in inches or millimeters. The majority of motorcycle tires are measured in inches in the United States, while the rest of the world uses the metric system. This article will help you understand how to convert motorcycle tire sizes from inches to metric.
Understanding Tire Size
Motorcycle tire size is usually written on the sidewall of the tire. It consists of a series of numbers and letters that indicate the tire's width, aspect ratio, construction type, and diameter. For example, a tire size of 120/70ZR17 indicates that the tire is 120 millimeters wide, has an aspect ratio of 70% (the height of the tire is 70% of its width), is a radial construction type, and has a diameter of 17 inches.
Inches to Metric Conversion
Converting motorcycle tire sizes from inches to metric is a simple process. The first step is to convert the width of the tire from inches to millimeters. To do this, multiply the width in inches by 25.4. For example, a tire with a width of 3.5 inches would be 88.9 millimeters (3.5 x 25.4 = 88.9).
The second step is to convert the diameter of the tire from inches to millimeters. To do this, multiply the diameter in inches by 25.4. For example, a tire with a diameter of 17 inches would be 431.8 millimeters (17 x 25.4 = 431.8).
Once you have the width and diameter in millimeters, you can write the tire size in metric format. For example, a tire with a size of 120/70ZR17 would be 120 millimeters wide, have an aspect ratio of 70%, be a radial construction type, and have a diameter of 431.8 millimeters.
Importance of Choosing the Right Size Tire
Choosing the right size tire for your motorcycle is crucial for safety and performance. A tire that is too small or too large can affect the handling and stability of the motorcycle. It can also affect the accuracy of the speedometer and odometer.
When replacing a tire, always make sure to choose the correct size tire for your motorcycle. Refer to the owner's manual or consult with a professional mechanic if you are unsure about the correct tire size.
Conclusion
Converting motorcycle tire sizes from inches to metric is a simple process that involves converting the width and diameter of the tire from inches to millimeters. Choosing the right size tire is crucial for safety and performance. Always make sure to choose the correct size tire for your motorcycle to ensure proper handling, stability, and accuracy of the speedometer and odometer.
