Sitrak Wheel and Tire (12R22.5-18PR Mixed Tread Pattern All-Position 22.5×9.00 10-Hole Φ335 Plastic Extension Spacer 8×4)
The Sitrak Wheel and Tire (12R22.5-18PR Mixed Tread Pattern All-Position 22.5×9.00 10-Hole Φ335 Plastic Extension Spacer 8×4) 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 12R22.5-18PR tubeless 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 robust 22.5×9.00 wheel assemblies, designed to provide a perfect balance between strength and weight. 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 use of high-quality steel and advanced manufacturing processes results in a wheel that is both durable and relatively lightweight, contributing to improved fuel efficiency and reduced unsprung mass. The wheel design also incorporates features that promote optimal brake cooling and reduce the risk of corrosion.
A key component for maintenance convenience is the inclusion of tubeless valves and plastic extension rods (spacers). These extension rods 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 plastic material is chosen for its durability, resistance to corrosion, and ability to withstand various environmental conditions without cracking or deforming. 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, operators also benefit from simplified inventory management and tire rotation practices.

Our assembly offers the significant operational advantage of an all-position tire design. 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. This universality simplifies fleet management by allowing tires to be rotated freely among all wheel positions, promoting even wear and extending the overall service life of the tire set. It also reduces inventory complexity, as only one type of tire needs to be stocked for replacements, leading to lower storage costs and simplified logistics for fleet operators.
The inclusion of high-quality ancillary components, such as the specific tubeless valves and durable plastic extension rods, demonstrates our commitment to providing a complete, user-friendly solution. These components are not afterthoughts but are integral to the system’s reliability. The extension rods ensure that maintaining proper tire pressure—a critical factor for safety, fuel economy, and tire longevity—is quick and easy, even on inner dual wheels. This attention to detail reduces maintenance time, encourages regular pressure checks, and helps prevent issues like underinflation, which can lead to premature tire failure and increased fuel consumption.
Every element in the Sitrak Wheel and Tire assembly is manufactured to the exacting standards synonymous with the SINOTRUK Sitrak brand. From the steel used in the wheels and nuts to the rubber compound in the tires, materials are selected for their performance and durability. The assembly process includes multiple quality control checkpoints, including dimensional verification, balance testing, and load testing, ensuring that every unit delivered meets our high-performance benchmarks. This rigorous process minimizes the risk of defects and ensures consistent, reliable performance across all components, giving our customers peace of mind and reducing 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 optimized design of the wheel and tire combination contributes to lower rolling resistance and reduced vehicle weight, which directly improves fuel efficiency—a major operational expense. Backed by comprehensive technical support and warranty, investing in our Sitrak Wheel and Tire assembly is a strategic decision for maximizing uptime, safety, and the overall profitability of your trucking operations.
