i. Reasonable Matching The tires at the front and rear, left and right of the machinery must be reasonably matched. The tires assembled on the same machinery should ensure the same brand, specification, structure, tread pattern, and load. Radial tires and bias-ply tires cannot be mixed; tires with different rim diameters, widths, or different cross-sectional […]
