Tire Specifications
The 90/90-21 dual sport tire features specific dimensions that significantly impact its performance and compatibility with different types of motorcycles and terrains.
The first number, 90, represents the tire’s width in millimeters. This measurement refers to the distance between the tire’s sidewalls when it is mounted on a rim. A wider tire provides more stability and traction, especially on soft surfaces like sand or gravel.
The second number, 90, represents the tire’s aspect ratio, which is the ratio of its height to its width. A higher aspect ratio indicates a taller tire with a more rounded profile. This type of tire offers a more comfortable ride and better shock absorption on uneven terrain.
The final number, 21, represents the tire’s rim size in inches. This measurement refers to the diameter of the rim that the tire is designed to fit. A larger rim size typically accommodates a wider tire and can provide improved stability and handling.
Compatibility Considerations, 90/90-21 dual sport tire
When selecting a 90/90-21 dual sport tire, it is crucial to consider its compatibility with your motorcycle’s rim size and intended use. Using a tire that is too wide or too narrow for your rim can compromise performance and safety.

Additionally, the tire’s aspect ratio and rim size should be appropriate for the type of terrain you will be riding on. A taller tire with a higher aspect ratio is better suited for off-road adventures, while a shorter tire with a lower aspect ratio is more suitable for on-road riding.
Tread Design
The 90/90-21 dual sport tire features a distinctive tread pattern designed to enhance traction, handling, and stability on both on-road and off-road terrains.
The tread pattern consists of a combination of large, widely spaced knobs and smaller, closely spaced blocks. The large knobs provide excellent grip on loose surfaces, such as dirt and gravel, while the smaller blocks improve stability and handling on paved roads.
Traction
The large knobs on the tread pattern provide ample surface area for contact with the ground, resulting in excellent traction on soft surfaces. The widely spaced design allows mud and debris to clear easily, preventing the tire from becoming clogged and losing grip.
Handling
The smaller blocks on the tread pattern improve handling and stability on paved roads. The closely spaced design provides a smooth and consistent ride, while the staggered arrangement of the blocks reduces road noise and vibrations.
Stability
The combination of large knobs and smaller blocks creates a stable platform for the tire, enhancing stability and control in various riding conditions. The large knobs provide support and grip on uneven surfaces, while the smaller blocks help to maintain a consistent contact patch with the ground.
