What are the main differences between steel-belted tires and nylon tires?
1 Answers
Differences between nylon tires and steel-belted tires: 1. Different specification codes: Nylon tires: "-" represents nylon tires, and the specification is expressed as 900-16. Steel-belted tires: "R" represents steel-belted tires, and the specification is expressed as 900R16. 2. Different materials: Nylon tires: The main material is nylon, and the sidewall is marked with NYLON. Steel-belted tires: The main material is steel, with a fine steel wire mesh inside the rubber layer of the tire, and the sidewall is marked with STEEL. 3. Different structures: Nylon tires: Bias-ply, old-fashioned structure, with the carcass composed of multiple layers of crisscrossed nylon cord layers. Steel-belted tires: Radial carcass composed of a single layer of radial steel cord layers. The tread is fixed by multiple layers of steel belts, and the functions of the sidewall and tread pattern are relatively independent. 4. Different cord arrangements: Nylon tires: The carcass cords are arranged in a crisscrossed mesh pattern between layers, forming an angle of 35-45 degrees with the circumferential centerline of the tread. Steel-belted tires: The carcass cords are arranged parallel to each other in a radial pattern, forming a 90-degree angle with the circumferential centerline of the tread. 5. Different treads: Nylon tires: The tread is thinner, and the stress is mainly borne by the cord layers of the carcass, with the tread bearing only 10%~20% of the stress. Steel-belted tires: The tread is thicker and has a hard belt layer, capable of bearing 60%~75% of the stress. Advantages and disadvantages of nylon tires and steel-belted tires: 1. Nylon tires: Good longitudinal rigidity, suitable for medium-speed driving on ordinary roads, but the structural design is somewhat unreasonable, affecting development, and they are gradually being phased out. 2. Steel-belted tires: Less prone to punctures, large radial elasticity, good cushioning performance, and higher load capacity, but the sidewalls are thinner and more prone to damage, with poor lateral stability, high manufacturing technical requirements, and high costs.
