Definition & Sizes The Armor 16.9-28 tire is a heavy-duty tire for backhoe loaders, suitable for heavy-duty construction and material processing. "16.9-28" means the tire has a tread width of approximately 16.9 inches and a rim diameter of 28 inches. This size is common on backhoe loaders because they require high traction and a large load capacity. General Construction & Specifications High ply rating (typically 10-12 ply) to withstand heavy loads and pressure when hauling or towing equipment. The R-4 tread, or lug traction pattern, is designed for extreme conditions, featuring thick tread blocks, deep grooves, and reinforced sidewalls for resistance to punctures, abrasion, and impact. Tires are typically bias ply or radial, depending on the model; for heavy equipment use on dirt, bias ply may be preferred for its high lateral resistance. Technical & Functional Advantages High grip on uneven terrain such as dirt, rocks, mud, or contaminants, thanks to the deep lug profile and self-cleaning tread pattern. Resistance to wear, cuts, and mechanical damage thanks to a special rubber composition and strong sidewall construction. Good stability and control even under maximum load conditions, especially when lifting, loading, or maneuvering on rough surfaces. Long service life with proper maintenance: proper inflation (if pneumatic tires), tire rotation, and regular inspection for tread and sidewall damage. Ideal Uses Backhoe loaders used in construction projects, dredging, excavation, filling, or work requiring heavy loads and power. Work locations where the ground surface is rough, rocks, contaminants, damp or muddy. Heavy operations and high work frequency require tires to withstand extreme conditions and minimize downtime.
