1. What Are All Steel Radial OTR Pnues?

All Steel Radial OTR Pnues refer to off-the-road tires designed with a radial structure and reinforced with steel belts across the entire carcass. Unlike conventional tires that may rely on textile reinforcement, these tires utilize steel layers to enhance strength, durability, and resistance to extreme working environments.

These tires are widely used on heavy-duty machinery such as dump trucks, loaders, graders, and mining vehicles operating in harsh conditions where durability and load capacity are critical.

Key Characteristics

• Steel belt reinforcement for maximum strength
• Radial tire structure for better flexibility
• High resistance to punctures and cuts
• Enhanced heat dissipation
• Improved traction on rough terrain

2. Why Are All Steel Radial OTR Tires Preferred Over Bias Tires?

The transition from bias-ply tires to radial tires in heavy industries has significantly improved operational performance. Radial tires distribute stress more evenly, resulting in better tire lifespan and fuel efficiency.

Main Advantages

• Better ground contact and traction
• Reduced rolling resistance
• Longer tread life
• Improved driving stability
• Higher load capacity

Companies such as Dongying Haorun specialize in producing advanced radial OTR tires that deliver consistent performance even in demanding mining and quarry operations.
