For Long Life of Your Wagon
All wooden wheels, light and heavy, should have a 'dish'. This dish creates a truss-like situation in the wheel that supports the wheel when the vehicle is turning or on a hillside. The size and style of the wheel determines the amount of dish. Proper dish is built into a wheel from the hub out. Axles and boxing's are machined and gauged to coincide with the angle of dish in each wheel. Note: On a wagon, the dish of the front wheels will be different from those of the rear because the diameters are different.
