The 22.5×9.00 Wheel Assembly is a heavy‑duty steel wheel engineered for the Sitrak C7H, offering a perfect balance of strength and weight. Its 22.5‑inch diameter and 9.00‑inch width provide an ideal fit for the 315/70R22.5 tires. This wheel features a precision‑machined mounting face and 10‑stud bolt pattern, ensuring a secure, vibration‑free attachment. The durable powder‑coat finish resists corrosion and road debris, making it a reliable choice for long‑haul and off‑road applications.
The Tubeless Tire Assembly is a premium radial tyre designed for steering axles, featuring a longitudinal tread pattern that delivers excellent straight‑line stability, low rolling resistance, and superior wet grip. With a load index of 151/148 (single/dual), it supports heavy loads while maintaining outstanding durability. The 18‑ply rating ensures high resistance to impacts and punctures, making it ideal for demanding highway and regional haulage. This tyre is tubeless, reducing weight and improving heat dissipation, which extends tread life and enhances fuel economy.
The Wheel Nut is a high‑strength, zinc‑plated fastener designed specifically for the C7H’s wheel mounting system. It features a conical seat that mates perfectly with the wheel’s stud holes, ensuring even clamping force and preventing wheel loosening. Each nut is manufactured from grade 10 steel and heat‑treated for maximum durability, capable of withstanding the high torque loads encountered during heavy braking and acceleration. The kit includes forty nuts, sufficient for all seven wheel assemblies.
Our Wheels and Tires are manufactured to Sinotruk’s original equipment specifications, guaranteeing flawless compatibility with the C7H’s axle hubs and brake systems. Every wheel, tire, and nut is engineered to perform as a matched set.
The tubeless radial tires offer excellent resistance to punctures and heat buildup, while the steel wheels and high‑strength nuts ensure a secure, vibration‑free ride. This Wheels and Tires combination enhances vehicle stability and reduces the risk of blowouts.
This Wheels and Tires kit provides everything needed for a full axle set – seven wheels, seven tires, and forty nuts. No additional parts are required, simplifying the replacement process and saving valuable workshop time.
The longitudinal tread pattern and tubeless design reduce rolling resistance, contributing to lower fuel consumption. The high‑quality materials and precise engineering ensure that these Wheels and Tires deliver exceptional mileage and low total cost of ownership.
The Wheels and Tires are among the most critical components of any heavy‑duty truck, directly influencing ride quality, fuel efficiency, and overall safety. This genuine Sitrak C7H kit combines precision‑engineered steel wheels, high‑performance tubeless radial tires, and durable wheel nuts to deliver a complete, ready‑to‑install solution for fleet operators and owner‑drivers alike.
The 22.5×9.00 wheel is the industry standard for heavy trucks, offering a robust platform that supports the vehicle’s weight while accommodating the large‑diameter tires required for modern powertrains. Its 10‑stud hub‑piloted mounting system ensures even load distribution, reducing stress on the wheel studs and improving wheel retention.
The tubeless tire assembly is specifically designed for steering axle applications, featuring a longitudinal tread pattern that minimises rolling resistance and provides excellent straight‑line tracking. This is especially important for highway driving, where fuel efficiency and tire wear are key operational concerns. The 315/70R22.5 size offers a perfect balance between load capacity and footprint, ensuring optimal traction and braking performance.
The tire’s 18‑ply rating (18PR) indicates its high load‑carrying capacity and resistance to penetration, making it suitable for both on‑road and light off‑road conditions. The load index of 151 (single) and 148 (dual) means each tire can support up to 3,450 kg when used singly and 3,150 kg when in dual configuration, providing ample margin for fully laden operations.
The wheel nuts are a critical yet often overlooked component. Our genuine nuts feature a conical seat that matches the wheel’s taper, ensuring that the clamping force is applied evenly across the mounting surface. This prevents wheel loosening, reduces the risk of stud failure, and extends the service life of both the wheel and the hub.
Installation of these Wheels and Tires is straightforward, provided standard workshop equipment is used. The wheels are balanced to ISO standards, and the tires are pre‑inflated to the recommended pressure (typically 8.5 bar for steering axles). The nuts should be torqued to 550‑600 Nm in a star pattern to ensure even clamping.
Regular inspection of the Wheels and Tires is essential for safety and longevity. Check for signs of uneven wear, cuts, or bulges on the tires, and ensure that the wheel nuts remain tight. The longitudinal tread pattern is designed to self‑clean, reducing the risk of stone retention and subsequent damage.
For fleet operators, standardising on these genuine Wheels and Tires ensures consistent performance across the fleet, simplifies inventory management, and reduces the risk of compatibility issues. The high‑quality materials and precision engineering result in lower total cost of ownership, thanks to extended tire life and reduced maintenance downtime.
The 22.5×9.00 wheel’s offset and backspacing are optimised for the C7H’s suspension geometry, ensuring proper wheel alignment and minimising steering effort. This contributes to reduced driver fatigue and improved vehicle stability at high speeds.
The tubeless design eliminates the need for inner tubes, reducing weight and improving heat dissipation. This is particularly beneficial for long‑distance haulage, where tire temperatures can rise significantly. The reduced weight also contributes to better fuel economy and lower CO₂ emissions.
We recommend that these Wheels and Tires be installed by trained professionals using calibrated torque wrenches and proper lifting equipment. The wheel nuts should be re‑torqued after the first 100 km of driving, as the wheel and hub surfaces settle.
The longitudinal tread pattern is also effective in dispersing water, reducing the risk of hydroplaning on wet roads. This enhances safety during adverse weather conditions, a critical consideration for trucks operating in all climates.
The 18‑ply rating, combined with the robust steel carcass, provides excellent resistance to sidewall damage, making these tires suitable for regional distribution routes that may include rough roads or construction sites.
We back our Wheels and Tires with a 12‑month warranty against manufacturing defects. Our technical support team is available to assist with any installation or compatibility questions.

Choosing genuine Wheels and Tires ensures that your C7H maintains its original ride quality, handling, and safety characteristics. Aftermarket wheels may have incorrect offsets or load ratings, leading to handling issues or premature failure.
The wheel nuts are supplied with a corrosion‑resistant coating that prevents seizing, making future wheel removal easier. This is a small but important detail that can save significant time during roadside tyre changes.
The tire’s load index of 151/148 ensures that the vehicle can operate at its maximum gross vehicle weight without compromising tire integrity. This is essential for compliance with weight regulations and for ensuring safe operation.
