Sitrak Wheel and Tire (11R22.5-16PR Mixed Tread Pattern All-Position 22.5×8.25 10-Hole Φ335 Plastic Extension Spacer 8×4)

The Sitrak Wheel and Tire (11R22.5-16PR Mixed Tread Pattern All-Position 22.5×8.25 10-Hole Φ335 Plastic Extension Spacer 8×4) is a comprehensive, all-position wheel and tire assembly specifically designed for 8×4 heavy-duty trucks. This kit is engineered to provide a balanced blend of traction, durability, and fuel efficiency across all axle positions. The assembly features 11R22.5-16PR tubeless radial tires with a mixed tread pattern, which combines the straight grooves of a highway tread with the lateral biting edges of a traction tread. This design offers versatile performance suitable for both on-road and light off-road conditions, providing reliable service in diverse operating environments.

At the core of this assembly are the robust 22.5×8.25 wheel assemblies. These wheels are constructed from high-quality steel and feature a 10-hole bolt pattern with a Φ335 bolt circle diameter, ensuring secure mounting and compatibility with standard heavy-duty truck hubs. The 8.25-inch width provides an optimal footprint for the 11R22.5 tires, promoting even wear and stable handling. The wheels are designed to withstand the stresses of heavy loads and frequent use, offering a reliable foundation for the tire assembly. Their construction focuses on durability without excessive weight, contributing to overall vehicle efficiency.

This package includes essential maintenance accessories such as tubeless valves and plastic extension rods (spacers). The extension rods are a crucial feature for dual-wheel configurations, allowing easy access to the inner valve stems for pressure checks and inflation. Made from durable, weather-resistant plastic, these rods prevent corrosion and ensure a reliable seal. By facilitating regular tire pressure maintenance, these components help maximize tire life, improve fuel economy, and enhance overall safety. The inclusion of high-grade wheel nuts ensures a secure, vibration-resistant attachment of the wheels to the hub.

Manufactured under the stringent quality standards of SINOTRUK Sitrak, this complete assembly is tested for load capacity, durability, and performance. The 16PR (Ply Rating) tires offer a substantial load index of 146/143, making them suitable for a wide range of freight applications. The all-position design provides operational flexibility, allowing fleet managers to maintain a single tire type for their entire 8×4 fleet, simplifying inventory and maintenance procedures. This assembly represents a practical, reliable, and cost-effective solution for truck operators seeking to optimize their vehicle’s performance and reduce total operating costs.

Our assembly provides exceptional versatility through its all-position, mixed tread tire design. The mixed tread pattern offers a balanced performance profile, delivering reliable traction for acceleration and braking, effective water evacuation for wet-weather safety, and reasonable rolling resistance for fuel efficiency. This makes the tire suitable for use on any axle of an 8×4 truck, greatly simplifying fleet management. Operators can maintain a single tire inventory, implement straightforward rotation patterns, and reduce the complexity associated with managing multiple tire types for different positions, leading to operational efficiencies and cost savings.

The 22.5×8.25 wheel assemblies are engineered for durability and reliable performance. Their design provides a solid and stable base for the tires, ensuring even load distribution and contributing to predictable handling. The 10-hole Φ335 bolt pattern is a common industry standard, ensuring broad compatibility and ease of sourcing replacement parts if needed. The inclusion of tubeless valves and high-quality plastic extension rods demonstrates our attention to the practicalities of maintenance, making routine pressure checks and inflation simple tasks that encourage proper tire care, which is fundamental to safety and longevity.

Every component in this SINOTRUK Sitrak assembly undergoes rigorous quality control. The tires are built with robust casings and advanced rubber compounds to resist wear, cuts, and weathering. The wheels are manufactured from certified materials and subjected to stress tests to verify their load-bearing capacity and structural integrity. The ancillary components, like the extension rods and nuts, are selected for their durability and precise fit. This comprehensive quality assurance process ensures that the entire assembly works together seamlessly, providing reliable service and minimizing the risk of premature failures that can cause costly downtime.

Choosing our complete Sitrak Wheel and Tire assembly represents a smart investment in value and reliability. By providing a perfectly matched kit from a single trusted source, we eliminate compatibility guesswork and installation errors. This not only saves time during initial fitting but also reduces long-term maintenance complexity. The balanced design of the assembly promotes even tire wear, extended service life, and consistent vehicle performance.
