Matching off-highway tyres with the right wheel

Matias Salonen, product manager at Nokian Tyres, sheds light on a critical aspect often overlooked in heavy-duty machinery: the importance of selecting the appropriate wheel to complement your off-highway tyre. While it may seem like a straightforward task, Salonen emphasises that not every wheel fits a particular tyre, and understanding why the choice of heavy-duty wheels matters is paramount for ensuring optimal performance of the complete wheel assembly.

“When purchasing tyres, the wheels may appear to be a necessary inconvenience,” comments Salonen. “However, the characteristics of the heavy-duty wheel play a significant role in ensuring the complete package functions correctly. Various factors determine the suitable use for a wheel.”

In the world of heavy-duty machinery, where challenges such as navigating through rugged terrains, carrying heavy loads, and maintaining high speeds are commonplace, the characteristics of the wheel are of utmost importance. Unlike tyres, which may be replaced multiple times throughout a machine’s lifespan, wheels are typically a one-time purchase expected to endure the rigours of heavy-duty operations. Hence, the reliability and durability of the wheel are non-negotiable, with any failure deemed unacceptable.

Traction a key consideration

Selecting the right wheel entails considering various factors, beginning with traction requirements. Salonen explains that while agricultural and forestry tyres may share similar wheel profiles, their traction needs differ significantly. For lighter loads, a smooth contact surface between tyre and wheel suffices, whereas knurling becomes necessary to prevent tyre slippage under high loads and torques. This knurling not only enhances grip but also accommodates varying tyre pressures without compromising traction.

Moreover, the wheel profile design is crucial for ensuring seamless tyre installation and proper functionality. Salonen stresses the importance of using wheels with the correct profile to facilitate tyre installation and ensure longevity and performance.

Durability especially important in heavy-duty applications

Durability is another key aspect, especially in heavy-duty applications where wheels are subjected to heavy loads and external impacts. Salonen discusses advanced reinforcements, such as Nokian Tyres’ Tube-Edge reinforcement, designed to enhance wheel rigidity and longevity in unforgiving environments.

Matching heavy-duty wheels to specific work requirements involves considering factors like wheel size, durability, and stability across different industries. From agriculture to forestry and earthmoving, each sector has unique demands that require specialized wheel solutions to ensure optimal performance and reliability.

A cohesive unit

In conclusion, Salonen emphasises the importance of viewing heavy-duty wheels and tyres as a cohesive unit rather than separate components. “The way I see it, heavy-duty wheels and tires should not be considered separately but rather as a combination of perfectly matched properties. No one is satisfied if the wheel does not function properly, and premium tyres fall apart,” he states.

By selecting the right combination of wheels and tyres, machinery operators can maximise performance, durability, and efficiency, ultimately unlocking the full potential of their equipment. “Ideally, wheels are designed for tyres, and tyres are designed for wheels. The proper support brings out the best in both your tyres and your machinery,” says Salonen in closing.
