Dual Sport tire measurements:

Dual Sport tires are commonly measured in millimeters by Width / Aspect Ratio x Rim Diameter (inches).

Term definitions:

• Aspect Ratio: The aspect ratio is the height of the sidewall in relation to the width of the tread. For example, if you have a tire that is 160/60R-17, the aspect ratio is 60% of the tread width (the first number in the tire size), creating a 96 millimeter sidewall height. Note to remember: Width is in millimeters, aspect ratio is a percentage, and rim diameter is in inches.
• Radial: Radial constructed tires utilize both ply and breaker (or belt) cords. The Ply cords extend from bead to bead at approximately 90 degree angle to the centerline of the tire. The breaker (or belt) cords are placed on top of the ply cords across the width of the tire. Advantages: Adding breaker (or belt) cords results in a stiffer carcass which helps provide a longer tread and tire life, better steering control and handling, overall smoother ride and ride comfort, and higher tread puncture resistance.
• Bias Belted: A Bias Belted tire utilizes ply cords that extend diagonally from bead to bead relative to the centerline and a stabilizer belt across the width of the tire. Advantages: This type of tire provides a smooth ride that is similar to the bias tire, but lessens rolling resistance due to belts increasing tread stiffness. The plies and belts are at different angles, which improves performance that compare to non-belted bias tires.
• Bias: Bias tires typically have the ply cords that extend diagonally from bead to bead at a range of 30 to 60 degree angles from the centerline. Each successive ply is laid at an opposing angle, forming a criss-cross pattern. Advantages: The design allows the entire tire body to flex easily, giving a comfortable ride on rough surfaces.

SAFETY:

Inspect and check tire pressure often. This is the most important tire-maintenance function you can perform. Refer to your machine's documentation for proper maintenance. Always give tires a gentle "run-in" period of 100 miles to get the feel of new tires-This means they should not be subjected to maximum power, abrupt lean-over,hard cornering, etc. Always match the front and rear tires for optimal handling, safety and performance. Mixing radials, or mixing radials with bias or belted-bias tires, may adversely affect handling and stability.

WARNING:

The charts and information on this page do not imply interchangeability. Consult your machine's manual to determine correct replacements, clearances, compatibility and stability, load-bearing capacity, speed rating, radial vs. non-radial, pattern and tread compound requirements, inflation recommendations and front-to-rear tire matching. Wrong selection can result in tire failure or loss of control with serious injury or death.
