12.00-20 Tire and 8.50-20/1.7 Rim Wheel Assembly, suitable for underground mining and general operating conditions.

The 12.00-20 pneumatic tire paired with the 8.50-20/1.7 rim wheel assembly constitutes a highly reliable mobility solution specifically designed for underground mining and subterranean engineering vehicles. Widely utilized in underground mining haul trucks, service vehicles, and auxiliary operational equipment, this assembly is engineered to meet the demands of continuous operation under conditions involving heavy loads, severe impacts, complex terrain, and harsh environments.
This wheel assembly consists of a 12.00-20 industrial pneumatic tire and an 8.50-20/1.7 steel rim; through a meticulously engineered design match, the two components achieve an optimal balance between load-bearing capacity and operational stability.
The 12.00-20 pneumatic tire delivers exceptional cushioning and shock-absorption capabilities, effectively absorbing impact loads from the mine roadway floor to enhance vehicle ride smoothness. Conversely, the 8.50-20/1.7 rim is manufactured from high-strength steel, featuring a structural design that reinforces load-bearing zones and critical stress points, thereby ensuring stable and reliable performance even under heavy-load conditions.
Suitable for heavy-duty transport operations in underground mines, it is capable of withstanding the sustained pressures associated with frequent loading cycles and high-intensity operations.
Specifically designed to navigate the challenging environments of mine roadways—characterized by loose rock, potholes, and obstacles—it effectively mitigates the risk of rim deformation and structural damage.
The precise matching of the tire and rim enhances overall operational stability, minimizing abnormal vibrations and uneven tire wear.
In high-risk underground operational settings, it significantly improves vehicle driving safety and ensures the stable, reliable operation of both personnel and equipment.
Leveraging HYWG’s comprehensive rim manufacturing supply chain capabilities—spanning the entire process from rim profile steel R&D and forming to welding and final assembly—the production process is under complete in-house control. A rigorous quality inspection system ensures that every wheel assembly meets the exacting requirements of mining applications regarding dimensional precision, structural integrity, and fatigue life.
With its combination of high reliability, superior safety, and exceptional durability, the 12.00-20 pneumatic tire + 8.50-20/1.7 rim wheel assembly provides a robust mobility foundation for underground mining vehicles, standing as a critical component choice for enhancing mining transport efficiency and overall equipment performance.
