Rim size significantly impacts vehicle performance, safety, fit, and economy, particularly in mining vehicles , loaders, graders, and other construction machinery. Large and small rims each have their own advantages, with varying performance, comfort, fuel consumption, and appearance.
Larger rims can usually match larger diameter tires, thus supporting higher loads . For large rigid dump trucks like the Cat 777 , we equip it with 49-inch ( 19.50-49/4.0 ) rims to withstand loads of hundreds of tons.
At the same time, wide rims can provide greater tread support, reduce tire deformation, improve cornering stability and anti-overturning performance , and also provide stronger impact resistance during work .
High-strength rims ensure tires do not burst due to deformation or cracking under high temperatures and high loads. The multi-piece structure facilitates disassembly and maintenance, reducing downtime.
The tires paired with small rims have a higher profile and thicker sidewalls, which can better absorb road impact and provide a softer and more comfortable riding experience.
Because the rim is smaller, it's lighter and has lower inertia. When paired with narrower tires, this effectively reduces rolling resistance, thereby lowering fuel consumption. In scenarios requiring frequent turns or operating in confined spaces, smaller rims offer improved maneuverability and turning radius. This is crucial for light construction machinery or agricultural vehicles , as the lighter overall wheel weight allows for more responsive acceleration.
We are a leading manufacturer specializing in the research, development, and manufacturing of construction machinery rims. We are committed to providing high-performance, long-life, heavy-duty rim solutions to customers worldwide. Our products are widely used in off-road vehicles such as mining dump trucks, loaders, graders, bulldozers, and forklifts . They come in 1-, 3-, and 5- piece configurations, with sizes ranging from 8 inches to 63 inches.
In the field of wheel rim manufacturing, we are committed to building an integrated manufacturing system for the entire industry chain to comprehensively improve product quality and delivery efficiency.
The factory achieves independent control over the entire process from raw material production , steel cutting, forging and forming, machining, to welding and assembly, surface treatment, testing and packaging, and builds a highly integrated, intelligent and efficient production chain.
We carefully select high-strength, low-alloy structural steel to ensure that each wheel rim is stable and reliable under extreme operating conditions such as mines, ports, loading stations, and excavation. Automated welding equipment and a rigorous quality control system enable highly consistent and precise mass production. Strict control of every process ensures dimensional accuracy and product consistency. Advanced electrostatic spraying and electrophoretic coating processes not only enhance corrosion resistance but also ensure a long lifespan and a high-quality appearance.
With more than 20 years of deep cultivation and accumulation, we have served hundreds of OEMs around the world and are the original rim supplier in China for well-known brands such as Volvo, Caterpillar, Liebherr, and John Deere.
We have a long history of designing and manufacturing high-quality rims for a variety of off-road vehicles . Our R&D team, comprised of senior engineers and technical experts, is focused on the research and application of innovative technologies, maintaining our leading position in the industry. We have established a comprehensive after-sales service system, providing timely and efficient technical support and after-sales maintenance. Every process in our rim production adheres to strict quality inspection procedures, ensuring that each rim meets international quality standards and meets customer requirements.
TRACTION's rims have undergone rigorous validation by host customers, and TRACTION has extensive and loyal partners in the global market.
