4011.20.50.30 - For use on a rim measuring 40.6 cm or more in diameter

This HTS classification, 4011.20.50.30, specifically designates new pneumatic tires made of rubber that are designed for use on buses or trucks and are intended for off-the-highway applications. The defining characteristic for this category is the tire's suitability for mounting on a rim with a diameter of 40.6 centimeters (equivalent to 16 inches) or larger. This size specification is crucial for differentiating these heavy-duty tires from those intended for smaller vehicles or passenger cars.

The distinction from its sibling category, 4011.20.50.50 (Other), lies in the precise rim diameter requirement. While both fall under "off-the-highway" tires for buses and trucks, category 4011.20.50.30 is narrowly defined by the 40.6 cm or greater rim diameter. The "Other" sibling would encompass off-the-highway tires for buses and trucks that do not meet this specific diameter threshold, or potentially other unique characteristics not captured by the 40.6 cm criterion.

As this classification represents a leaf node, there are no further subcategories. Therefore, the focus for classification at this level is solely on confirming that the pneumatic tire is new, made of rubber, intended for bus or truck use on or off the highway, and specifically designed to fit a rim with a diameter of 40.6 centimeters or more. Examples include tires for large mining vehicles, construction equipment, or heavy-duty agricultural machinery operating in non-road environments.
