Motorcycle Tire Conversion Chart Inches To Metric
When it comes to choosing the right tires for your motorcycle, one of the most important things to consider is the size. There are two main measurement systems used for motorcycle tires: inches and metric. While some tires are only available in one size, others can be converted from one measurement system to the other. In this article, we'll be discussing the motorcycle tire conversion chart from inches to metric, so you can make the best choice for your ride.
Understanding Motorcycle Tire Sizes
Before we dive into the conversion chart, let's take a quick look at how motorcycle tire sizes are measured. There are three main components to a tire size:
- Width - this is the measurement of the tire from sidewall to sidewall, in millimeters or inches.
- Aspect ratio - this is the ratio of the tire's height to its width, expressed as a percentage.
- Rim diameter - this is the diameter of the wheel rim that the tire is designed to fit onto, in inches or millimeters.
So, for example, a common tire size for sport bikes is 120/70ZR17. This means that the tire has a width of 120 millimeters, an aspect ratio of 70%, and is designed to fit onto a 17-inch wheel rim.
The Motorcycle Tire Conversion Chart
Now that we understand how motorcycle tire sizes are measured, let's take a look at the conversion chart from inches to metric. Here are the most common tire sizes, listed in both inches and millimeters:
| Inches | Metric |
|---|---|
| 2.50 | 80 |
| 2.75 | 90 |
| 3.00 | 100 |
| 3.25 | 110 |
| 3.50 | 120 |
| 3.75 | 130 |
| 4.00 | 140 |
| 4.25 | 150 |
| 4.50 | 160 |
| 4.75 | 170 |
| 5.00 | 180 |
| 5.10 | 190 |
| 5.50 | 200 |
| 6.00 | 210 |
| 6.25 | 220 |
| 6.50 | 230 |
| 7.00 | 240 |
So, for example, if you have a tire that is 3.50 inches wide, you can convert that to 120 millimeters using the chart above. It's important to note that these measurements are not exact, and there may be slight variations between different tire brands and models.
Choosing the Right Tires for Your Motorcycle
Now that you understand how to convert tire sizes from inches to metric, it's important to choose the right tires for your motorcycle. There are many factors to consider, including your riding style, the type of motorcycle you have, and the road conditions you'll be riding on.
It's always a good idea to consult with a professional mechanic or tire specialist to determine the best tires for your specific needs. They can help you choose the right size, tread pattern, and construction to ensure that you get the most out of your motorcycle.
Conclusion
Choosing the right tires for your motorcycle is essential for safety and performance. By understanding how to convert tire sizes from inches to metric, you can make an informed decision when it comes time to replace your tires.
