The standards that industrial tires need to meet cover national and industry regulations, physical and mechanical properties, and many other aspects. The formulation and implementation of these standards are of great significance to ensuring the quality, safety performance and service life of tires. At the same time, with the continuous advancement of science and technology and the improvement of environmental protection requirements, these standards will continue to be updated and improved.
1. National and industry standards
GB/T 16622: For press-fit solid tires, their specifications, dimensions, speeds and loads need to meet the relevant provisions of GB/T 16622.
Reinforced truck tire standards: There are 15 specifications for reinforced truck and light truck tires included in the national standard, which have clear provisions in terms of tire section width, flatness, tire diameter, etc.
Tire production standards: The national regulations on tire production standards include tire identification, anti-counterfeiting identification, tire load index, speed level, tire pattern and tire brand. These standards are intended to ensure the authenticity and quality of tires, as well as the use environment and performance of tires.
2. Physical and mechanical performance standards
Tensile strength: The tensile strength of a tire is an important indicator of its ability to withstand tension, and the tensile strength is generally required to be ≥20Mpa.
Elongation at break: The elongation at break reflects the deformation ability of the tire when subjected to tension, and the elongation at break is generally required to be ≥350% (tread rubber).
Hardness: The hardness of the tire has an important influence on its wear resistance and service life. Generally, the hardness is required to be within the range of 75±5 Shore A.
Wear: Wear is an important indicator to measure the wear resistance of the tire. Generally, the wear (Akron) is required to be ≤0.305.
Load-bearing capacity: The load-bearing capacity of the tire is one of its key performance indicators. Generally, the load-bearing capacity is required to be ≥6000 pounds (load wheel) or ≥4000 pounds (guide wheel).
3. Other standards
Metal-rubber adhesion strength: For press-fit solid tires, the metal-rubber adhesion strength is also an important indicator, generally requiring ≥10K/M.
Durability: After the durability test is carried out according to the prescribed test method, the tire should not separate or bulge.
Environmental protection standards: With the improvement of environmental awareness, industrial tires also need to meet relevant environmental protection standards, such as reducing the emission of harmful substances and improving resource utilization efficiency.
