4011.90 - Other:

This HTS category, 4011.90, encompasses pneumatic tires of rubber that are not specifically categorized under headings for motor cars, buses or trucks, aircraft, motorcycles, or bicycles. This includes tires designed for a broad spectrum of other vehicles and machinery where the primary application is not one of the specifically enumerated uses. Examples could include tires for industrial equipment, agricultural machinery, trailers not attached to passenger vehicles, or certain off-road vehicles.

The defining characteristic of this category is its residual nature. Unlike sibling categories such as 4011.10 (motor cars), 4011.20 (buses or trucks), 4011.30 (aircraft), 4011.40 (motorcycles), and 4011.50 (bicycles), this sub-heading is for tires whose primary intended use does not fall into those specific types of vehicles. Therefore, classification here depends on excluding the tire from those more specific categories.

Within 4011.90, further subdivisions exist to refine classification based on tire construction and tread pattern. Sub-category 4011.90.10 specifically addresses tires with a "herring-bone" or similar tread pattern, often found on tractors or heavy-duty equipment. The 4011.90.20 designation is for radial tires within this residual group, distinguishing them by their internal construction. The remaining tires, not fitting the aforementioned specific tread or construction types, fall under the general classification of 4011.90.80, "Other."
