The manufacturing process for modern fire wheels typically involves the following steps:

Design: The first step in the manufacturing process is to design the fire wheel. This involves creating a 3D model using computer-aided design (CAD) software. The design must take into account the intended use of the fire wheel, as well as any safety requirements.

Material selection: Once the design is complete, the materials for the fire wheel must be selected. Modern fire wheels are typically made from high-strength, heat-resistant materials such as steel, aluminum, or titanium.

Machining: The next step is to machine the materials into the shape of the fire wheel. This is typically done using computer numerical control (CNC) machines, which can precisely cut and shape the metal.

Heat treatment: After the fire wheel is machined, it undergoes a heat treatment process to increase its strength and durability. This typically involves heating the metal to a specific temperature and then cooling it slowly to produce the desired properties.

Assembly: Once the heat treatment is complete, the various components of the fire wheel are assembled. This may involve welding, bolting, or other joining techniques.

Testing: Before the fire wheel can be used, it must undergo extensive testing to ensure it meets safety standards and performs as intended. This may involve static testing to check the strength of the fire wheel, as well as dynamic testing to simulate the stresses it will undergo during use.

Finishing: Finally, the fire wheel is finished to improve its appearance and protect it from corrosion. This may involve painting, powder coating, or other surface treatments.

Overall, the manufacturing process for modern fire wheels involves a combination of advanced design, machining, and testing techniques to produce a high-quality product that is both safe and reliable.

The process of removing a foam tire from a wheel can vary depending on the type of wheel and tire you are working with. Here is a general guide for removing a foam tire from a wheel:

Remove the wheel from the vehicle or equipment.
Use a tire iron or pry bar to break the bead of the tire by inserting it between the tire and the rim and applying pressure to push the tire away from the rim. Work around the entire circumference of the tire until the bead is broken.
Use a tire spoon or bead breaker tool to pry the tire away from the rim. Insert the tool between the tire and rim and pry the tire away from the rim by levering the tool downwards. Work around the entire circumference of the tire until it is completely separated from the rim.
Once the tire is removed, you can then remove the foam insert. If the foam insert is not already loose, you may need to cut it out with a sharp utility knife or scissors.
Inspect the wheel and tire for any damage or wear and make any necessary repairs or replacements.
When reassembling the tire and wheel, make sure the foam insert is properly aligned with the valve stem and that the tire is mounted evenly on the rim. Use a tire mounting machine or a manual tire iron and bead seater to re-seat the tire onto the rim.
Inflate the tire to the recommended pressure and test it for leaks or other issues before putting it back into service.
