Sitrak Wheels and Tires (295 80R22.5-18PR Longitudinal Tread Pattern All Wheel Positions Load Index 152 149 22.5×9.00 Φ335 8X4 New Zealand Order Specification)
The Sitrak Wheels and Tires (295 80R22.5-18PR Longitudinal Tread Pattern All Wheel Positions Load Index 152 149 22.5×9.00 Φ335 8X4 New Zealand Order Specification) is a specialized heavy-duty wheel and tire assembly configured specifically for the New Zealand market. This assembly meets the unique requirements of New Zealand’s transport industry, including compliance with local axle load regulations and performance standards for long-distance travel on both highways and rural roads. The 295/80R22.5-18PR tubeless radial tires feature a longitudinal tread pattern, optimized for excellent directional stability, wet weather performance, and low rolling resistance.
This specification includes robust 22.5×9.00 wheel assemblies, which provide a strong and stable base for the tires. The wheels feature a 10-hole bolt pattern with a Φ335 bolt circle diameter, ensuring a secure fit on standard heavy-duty truck hubs common in New Zealand fleets. The assembly is designed as an all-wheel position solution, meaning the same tire and wheel combination can be used on steering, drive, and trailer axles of 8×4 trucks. This versatility simplifies inventory management and maintenance for transport companies operating throughout New Zealand.
Key to this assembly are the tubeless valves and plastic extension rods included for maintenance convenience. The extension rods allow easy access to inner valve stems on dual-wheel configurations, facilitating regular tire pressure checks and inflation. Maintaining correct tire pressure is particularly important in New Zealand’s varied climate and terrain, as it affects safety, tire wear, and fuel consumption. The Load Index of 152/149 indicates a high load-carrying capacity per tire, suitable for the heavy loads often transported on New Zealand roads.
Manufactured by SINOTRUK Sitrak, this assembly undergoes rigorous testing to ensure it meets the durability and performance demands of New Zealand’s transport sector. The longitudinal tread pattern is especially effective on New Zealand’s winding highways and in wet conditions, providing reliable grip and water dispersion. This complete wheel and tire package offers a ready-to-install solution for truck operators seeking to upgrade or replace their existing setups with a specification tailored for optimal performance and compliance in New Zealand.
