Motorcycle tire sizes can vary depending on the make and model of the motorcycle. The size of a motorcycle tire is typically expressed as a combination of three numbers, such as 120/70-18. The first number (120 in this example) is the width of the tire in millimeters. The second number (70 in this example) is the aspect ratio, which represents the height of the tire’s cross-section to its width. The third number (18 in this example) is the size of the wheel rim, expressed in inches.
The width of a motorcycle tire is typically measured in millimeters and is the first number in the tire size code. This measurement represents the width of the tire from sidewall to sidewall. A wider tire will typically provide better traction and stability, but may also be more prone to wear and tear due to the increased contact with the road.
The aspect ratio of a motorcycle tire is the second number in the tire size code and is a measure of the height of the tire’s cross-section relative to its width. This ratio is expressed as a percentage, with a higher aspect ratio indicating a taller tire. For example, a tire with an aspect ratio of 70 would have a height that is 70% of its width.
The third number in a motorcycle tire size code is the diameter of the wheel rim, which is typically expressed in inches. This measurement determines the size of the tire that can be fitted onto the wheel. A larger rim diameter will allow for a larger tire, which may provide improved handling and a more comfortable ride.
It’s important to note that motorcycle tire sizes can vary greatly depending on the make and model of the motorcycle, as well as the intended use of the tire. It’s always best to consult the owner’s manual or a motorcycle tire specialist to determine the appropriate tire size for your specific motorcycle.
