Sitrak Wheels and Tires (11.00R20-18PR Mixed Tread Pattern All-Position Reinforced 8.5-20 10-Hole Φ335 Extension Hose 8X4)
The Sitrak Wheels and Tires (11.00R20-18PR Mixed Tread Pattern All-Position Reinforced 8.5-20 10-Hole Φ335 Extension Hose 8X4) is a comprehensive, all-position wheel and tire assembly specifically engineered for heavy-duty trucks with 8×4 configurations. This assembly features a mixed tread pattern designed to deliver optimal performance across all wheel positions, including steering, drive, and trailer axles, providing balanced handling, traction, and wear characteristics. The 11.00R20-18PR radial tires offer a high load capacity and excellent resistance to impacts, punctures, and heat buildup, ensuring reliable performance in long-haul and regional transportation applications.
Central to this assembly are the reinforced 8.5-20 wheel assemblies, designed to provide exceptional strength and durability under heavy loads. The wheels feature a 10-hole bolt pattern with a Φ335 bolt circle diameter, ensuring secure mounting and compatibility with standard heavy-duty truck hubs. The reinforcement in the wheel design includes thicker materials and optimized structural supports, making them ideal for the most demanding operating conditions, including mining, construction, and heavy freight transport. This durability directly translates to longer service life and reduced replacement frequency.
A key component for maintenance convenience is the inclusion of air inlet extension hoses. These hoses allow for easy access to the valve stem for tire pressure monitoring and inflation, which is crucial for dual-wheel setups where the inner valve can be difficult to reach. The high-quality rubber material is chosen for its flexibility, resistance to oil and corrosion, and ability to withstand various environmental conditions without cracking. This thoughtful inclusion simplifies routine maintenance and helps ensure tires are kept at the correct pressure, which is vital for safety, tire life, and fuel economy.
Manufactured under the stringent quality control standards of SINOTRUK Sitrak, this complete wheel and tire package is designed as a direct, hassle-free replacement or upgrade for 8×4 trucks. It eliminates the complexity of sourcing and matching individual components, guaranteeing perfect compatibility and performance. The assembly is tested for load capacity, high-speed durability, and overall reliability, making it a trusted choice for fleet managers and owner-operators who prioritize safety, efficiency, and low total operating costs. By choosing an all-position design with reinforced wheels, operators also benefit from maximum durability and simplified inventory management.

Our assembly offers the significant operational advantage of an all-position tire design combined with reinforced wheels. The mixed tread pattern provides a versatile performance profile, delivering good traction for steering, effective power transfer for driving, and stable rolling resistance for trailer positions. The reinforced 8.5-20 wheels are built to withstand extreme loads and harsh environments, significantly reducing the risk of wheel failure and deformation. This combination ensures maximum uptime and reliability for trucks operating in demanding sectors like construction, logging, and heavy haulage.
The inclusion of high-quality air inlet extension hoses demonstrates our commitment to providing a complete, user-friendly solution. These hoses are not generic accessories but are specifically designed to fit the valve stems on this assembly, ensuring a perfect seal and easy operation. By making tire pressure checks and inflation quick and effortless—even on inner dual wheels—we encourage proper maintenance practices. Maintaining correct tire pressure is one of the most effective ways to prevent premature tire wear, improve fuel efficiency by up to 3%, and enhance overall vehicle safety.
Every element in the Sitrak Wheels and Tires assembly is manufactured to the exacting standards synonymous with the SINOTRUK Sitrak brand. The reinforced wheels undergo additional stress tests and quality inspections to ensure they meet higher load and impact resistance criteria. The tires are produced with advanced rubber compounds and steel belt construction for longevity and puncture resistance. This rigorous process minimizes the risk of defects and ensures consistent, reliable performance across all components, giving our customers peace of mind and reducing unexpected vehicle downtime.
Choosing our complete assembly translates into tangible cost savings and operational efficiency. By providing a perfectly matched kit, we eliminate compatibility concerns and installation errors that can occur when sourcing parts separately. This plug-and-play approach reduces workshop time and labor costs. Furthermore, the durability of the reinforced wheels and the all-position tire design extend service intervals and simplify inventory management. Backed by comprehensive technical support and warranty, investing in our Sitrak Wheels and Tires assembly is a strategic decision for maximizing uptime, safety, and the overall profitability of your heavy-duty trucking operations.
