The center part of the rims of the rear wheels is offset from the center by 2 or 3 inches. So the way they are now the overall width is narrower, but there's less space between the rear tires. If I flipped them around backwards I'd have a wider space between the tires. Is that ok? I'm not sure if the offset is specifically so that you can adjust the width this way, or if its because the weight of the tractor needs to be to the outside of the rims for some structural reason or something.
Also, with turf tires it doesn't matter which way the tread goes right?
