In the mining, construction machinery, agricultural, and industrial vehicle sectors, wheel rims are not only the carriers of tires but also the foundation for the safety and efficiency of the entire machine. As one of the world's top three OTR heavy-duty wheel rim manufacturers, HYWG is committed to providing high-strength, high-reliability, and high-consistency wheel rim solutions for the most demanding operating conditions.
For over 20 years, HYWG has been deeply involved in the OTR wheel rim market, including mining wheels, engineering machinery wheels, and agricultural and industrial wheels. Its products are widely used in mining dump trucks , wheel loaders, graders, bulldozers , underground and open-pit mining equipment , agricultural tractors, harvesters , and port and industrial vehicles .
Whether under high loads, strong impacts, long-term continuous operation, or complex terrain and harsh environments, HYWG rims have earned the trust of customers with their stable performance.
HYWG firmly believes that a reliable wheel rim must be reliable from the very beginning.
As one of the few Chinese companies capable of producing wheel rims across the entire supply chain, from steel to finished product , we independently manufacture the profile steel for wheel rims. This allows our products to outperform ordinary standard wheel rims in terms of concentricity , fatigue resistance , weld strength , and service life . High-strength, high-quality steel ensures that our wheel rims possess excellent fatigue and impact resistance .
From steel rolling, mold design, high-precision forming, automated welding to surface treatment and finished product inspection , this "one-stop" production model ensures that all products meet uniform high standards, truly realizing full-chain manufacturing and quality control of wheel rims.

HYWG boasts a research and development team comprised of senior engineers and technical experts, focusing on the research and application of innovative technologies. Through precise steel profile design and structural optimization, we enhance the overall strength of wheel rims under heavy load conditions , and strictly control welding processes and dimensional tolerances to ensure tire consistency and long-term stability .
At the same time, we will establish a comprehensive after-sales service system to provide timely and efficient technical support and after-sales maintenance, ensuring that customers have a smooth experience during use.
HY WG's rims must pass several key tests, including: appearance and welding inspection, radial and end face runout testing , non-destructive testing, and air tightness and sealing performance testing.
