Over the years I have seen 4, 6, 8 ply tires on just about any and all machines. I think it is/was more or less a thing that had to do more with the price of the tire then other things and 8 ply being the top of the line and 4 ply the cheaper ones. The heavier the ply the more it takes to get a thorn etc to the tube so less likely to have a flat. Now if you where talking about truck tires then that would be for handling a heavier load
