Sitrak Wheel and Tire (315 80R22.5-18PR Longitudinal Tread All-Wheel Position Lightweight 22.5×9.00 10-Hole Φ335 Plastic Extension Rod 8X4)

The Sitrak Wheel and Tire (315 80R22.5-18PR Longitudinal Tread All-Wheel Position Lightweight 22.5×9.00 10-Hole Φ335 Plastic Extension Rod 8X4) is a comprehensive wheel and tire assembly specifically engineered for heavy-duty trucks with 8×4 configurations. This assembly features a longitudinal tread pattern designed to deliver optimal performance across all wheel positions, including steering, drive, and trailer axles, providing excellent stability, water evacuation, and low rolling resistance. The 315/80R22.5-18PR tubeless radial tires offer a high load capacity with excellent resistance to hydroplaning, making them ideal for highway and long-distance applications.

At the heart of this assembly are the lightweight 22.5×9.00 wheel assemblies, engineered to reduce unsprung mass while maintaining structural integrity. 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 lightweight construction, achieved through advanced materials and design optimization, contributes significantly to improved fuel efficiency, better acceleration, and reduced wear on suspension components. Each wheel weighs approximately 34kg and comes complete with a valve, ready for installation.

A key maintenance feature of this package is the inclusion of high-quality plastic extension rods for the valve stems. These rods allow for easy access to the valve for tire pressure monitoring and inflation, which is particularly important for dual-wheel configurations where inner valves are difficult to reach. The plastic material is selected for its durability, corrosion resistance, and flexibility across a wide temperature range. This thoughtful design element promotes regular tire pressure checks, which are essential for safety, optimal tire wear, 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 rigorously 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. The all-position design with longitudinal tread offers predictable handling and extended tire life through even wear patterns.

Our assembly offers the distinct advantage of combining a specialized longitudinal tread pattern with lightweight wheel technology. The longitudinal tread provides superior directional stability, excellent wet-weather performance through efficient water channeling, and typically lower rolling noise compared to other patterns. This makes it an ideal choice for trucks that spend most of their time on highways. The lightweight 22.5×9.00 wheels directly reduce the vehicle’s unsprung mass, leading to measurable improvements in fuel economy, braking performance, and reduced stress on suspension components.

The all-wheel position compatibility of this assembly provides exceptional operational flexibility. Fleets can standardize on a single tire type for all positions on their 8×4 trucks, simplifying inventory management, tire rotation practices, and spare part logistics. This universality reduces administrative complexity and capital tied up in multiple tire stocks. The consistent performance profile across all axles also contributes to predictable vehicle handling and balanced wear, allowing for more accurate maintenance scheduling and cost forecasting.

Every component in the Sitrak Wheel and Tire assembly is manufactured to the exacting standards of SINOTRUK Sitrak. The lightweight wheels undergo rigorous testing for fatigue strength and impact resistance to ensure they meet durability requirements despite their reduced weight. The tires are constructed with advanced steel belt technology and rubber compounds designed for longevity and fuel efficiency. The plastic extension rods are tested for durability and seal integrity. This comprehensive quality assurance process ensures every unit delivers reliable, consistent performance.

Choosing our complete assembly translates into significant total cost of ownership (TCO) benefits. The initial investment is offset by the fuel savings from reduced rolling resistance and lighter weight, the extended service life from high-quality materials, and the operational savings from simplified maintenance and inventory. By providing a perfectly matched kit from a single trusted supplier, we eliminate compatibility risks and installation errors. Backed by comprehensive technical support, investing in our Sitrak Wheel and Tire assembly is a strategic decision for maximizing the efficiency, safety, and profitability of your highway-oriented trucking operations.
