Tire Size: 100/80 vs 90/90
When it comes to choosing the right tire size for your motorcycle, there are several factors to consider. Two of the most popular tire sizes are 100/80 and 90/90. But what's the difference between these two sizes, and which one is right for you?
What do the numbers mean?
Before we dive into the comparison, let's break down what the numbers in the tire size mean.
- The first number (100 or 90) represents the width of the tire in millimeters.
- The second number (80 or 90) represents the aspect ratio, which is the ratio of the tire's height to its width.
100/80 vs 90/90: Key Differences
Width
The most obvious difference between the two sizes is the width. A 100/80 tire is 10mm wider than a 90/90 tire. This may not seem like a lot, but it can affect the handling and stability of your motorcycle.
Aspect Ratio
The aspect ratio of a 100/80 tire is 0.80, while a 90/90 tire has an aspect ratio of 0.90. This means that a 90/90 tire is slightly taller and more narrow than a 100/80 tire.
Handling and Stability
The wider 100/80 tire provides better stability and handling, especially at high speeds. This is because the wider contact patch with the road gives you more grip and control. On the other hand, the narrower 90/90 tire is more suited for slower, more technical riding, such as in twisty mountain roads or off-road terrain.
Ground Clearance
The narrower 90/90 tire typically provides more ground clearance than a 100/80 tire. This can be beneficial for riders who frequently encounter rough terrain or potholed roads.
Fuel Efficiency
The narrower 90/90 tire also tends to be more fuel-efficient than a 100/80 tire. This is because it has less rolling resistance, which means less energy is wasted and more power is transmitted to the road.
Conclusion
When choosing between a 100/80 and a 90/90 tire, consider your riding style and the conditions you'll be riding in. If you prioritize stability and handling at high speeds, a 100/80 tire may be the better choice. However, if you frequently encounter rough terrain or prioritize fuel efficiency, a 90/90 tire may be the way to go. Ultimately, the right tire size for you will depend on your specific needs and preferences.
