4011.20.10 - Radial

This HTS subcategory, 4011.20.10, specifically covers new pneumatic tires made of rubber that are designed for use on buses and trucks. The key defining characteristic is their intended application and the corresponding structural and performance specifications required for these heavier-duty vehicles. This includes tires built to withstand significant load capacities, higher operating pressures, and the demands of frequent braking and acceleration associated with commercial transport.

Distinction from sibling category 4011.20.50, "Other," is crucial. While the latter encompasses a broader range of pneumatic tires for buses and trucks that do not meet the specific criteria of this "Radial" classification, 4011.20.10 exclusively applies to radial-ply construction. Radial tires feature internal cords running radially across the tire from bead to bead, with stabilizing belts placed circumferentially under the tread. This construction provides distinct advantages in terms of fuel efficiency, tread wear, and ride comfort compared to bias-ply tires.

Further classification within this category is determined by the intended operational environment. The subcategories "On-the-highway" and "Off-the-highway" differentiate tires based on whether they are primarily engineered for paved roads or for use on rough, uneven terrain such as construction sites, mining operations, or agricultural fields. This distinction guides the design of tread patterns, sidewall reinforcement, and overall tire structure to optimize performance and durability for each specific application.
