When choosing wheels for a camping folding wagon, you need to consider many factors, including terrain, usage environment, wheel material and design, etc. Here are some key points：
Universal wheels and off-road wheels: Universal wheels are suitable for smooth ground, such as cement floors, because they can rotate 360 degrees, turn easily, and are relatively light; off-road wheels are more suitable for uneven terrains, such as grass and beaches, because of their Stronger grip and less likely to slip.
Wheel material: Rubber wheels have good slip resistance and wear resistance, which can effectively improve driving stability and extend tire service life.
PU wheels and tank wheels: PU wheels are wear-resistant and chemical-resistant, and are suitable for a variety of environments; tank wheels use metal tracks, which have stronger off-road performance and are suitable for harsh road conditions.
Wheel size: Small-sized wheels (such as 5-inch) make the vehicle more flexible and suitable for narrow roads and complex terrain; large-sized wheels (such as 8-inch) are more laborious to operate, but in some cases have better passability.
To sum up, the choice of wheels for camping folding wagon should be based on specific usage scenarios and needs. If you often use it on flat ground, swivel wheels or narrow wheels may be a better choice; if you plan to use it in complex or harsh terrain, wide off-road wheels or tank wheels may be more suitable. At the same time, considering the material and size of the tires is also an important factor, which will affect the driving performance and service life of the vehicle.
