Sitrak Wheels and Tires (12.00R20-18PR Mixed Tread Pattern All-Position Reinforced 8.5-20 10-Hole Φ335 Extension Hose 8X4)

The Sitrak Wheels and Tires (12.00R20-18PR Mixed Tread Pattern All-Position Reinforced 8.5-20 10-Hole Φ335 Extension Hose 8X4) is a comprehensive, heavy-duty wheel and tire assembly specifically engineered for 8×4 trucks operating in challenging conditions. This assembly is built around the robust 12.00R20-18PR tire with a mixed tread pattern, designed to deliver versatile performance across all wheel positions. The mixed tread combines longitudinal grooves for water evacuation and lateral sipes for traction, making it suitable for varied road surfaces and weather conditions, from highways to construction sites.

A key feature of this assembly is the reinforced 8.5-20 wheel. These wheels are constructed with additional material and structural enhancements to withstand extreme loads and impacts that are common in mining, heavy construction, and logging applications. The reinforcement significantly reduces the risk of wheel bending, cracking, or failure under stress. The wheels feature a 10-hole bolt pattern with a Φ335 bolt circle diameter, ensuring a secure and precise fit on standard truck hubs, promoting stability and reducing vibration.

This package includes practical air inlet extension hoses, which are essential for efficient maintenance on dual-wheel setups. These hoses provide easy access to the inner valve stems, allowing for quick tire pressure checks and inflation without the need to remove outer wheels. Made from durable, flexible rubber resistant to oil and weathering, these hoses ensure a reliable air passage and encourage regular pressure maintenance, which is critical for tire longevity, fuel efficiency, and vehicle safety. The inclusion of high-torque wheel nuts guarantees a secure mounting that can handle the dynamic forces of heavy-duty operation.

Manufactured under the stringent quality standards of SINOTRUK Sitrak, this complete assembly is subjected to rigorous testing for load capacity (Load Index 154/151), high-speed endurance, and overall durability. The all-position design offers exceptional operational flexibility, allowing fleets to standardize their tire inventory and simplify rotation schedules. This assembly represents the pinnacle of heavy-duty component engineering, providing truck operators with a reliable, high-capacity solution that maximizes vehicle uptime and minimizes total operating costs in the most demanding environments.

Our assembly is specifically engineered for maximum durability in extreme conditions. The combination of reinforced 8.5-20 wheels and 18PR tires with a high load index (154/151) creates a system capable of handling the heaviest legal loads and the toughest terrains. The reinforced wheels are built to resist deformation and fatigue cracking, which are common failure points in standard wheels under constant heavy stress. This focus on structural integrity ensures the assembly can withstand the punishing environments of mining, quarrying, and heavy construction, providing unparalleled reliability and reducing the risk of catastrophic wheel failure.

The all-position mixed tread design offers a perfect balance of performance and versatility. The tread pattern provides sufficient traction for drive wheels, stable handling for steering axles, and even wear characteristics for trailer positions. This allows fleet managers to deploy a single tire type across their entire 8×4 fleet, dramatically simplifying inventory management, tire rotation strategies, and procurement processes. The mixed pattern also delivers a good compromise between fuel efficiency (from the longitudinal grooves) and all-weather safety (from the lateral biting edges), making it a highly practical choice for mixed-route operations.

We provide a complete, ready-to-install kit that includes every necessary component, from the major assemblies down to the critical extension hoses and wheel nuts. This eliminates the guesswork and compatibility issues that arise when sourcing parts from multiple suppliers. The air inlet extension hoses are a prime example of our attention to detail, solving a common maintenance headache and promoting proper tire care. By ensuring all components are designed to work together from the outset, we guarantee optimal performance, safety, and ease of installation, saving valuable workshop time and reducing the potential for errors.

Choosing SINOTRUK Sitrak means investing in a product backed by a global leader in heavy-duty truck manufacturing. Our wheels and tires assembly undergoes a comprehensive quality assurance process, including material certification, dimensional checks, load testing, and endurance validation. This commitment to quality translates into longer service intervals, reduced unscheduled downtime, and lower total cost of ownership. For operators who cannot afford failures, our Sitrak Wheels and Tires assembly offers the peace of mind that comes with proven performance, robust engineering, and the support of a trusted brand dedicated to keeping heavy trucks moving.
