What's up with the skinny rear ag tires on the 4025 4wd?

It is kind of odd that they put such a nice big wide R4 set of tires on this model and a comparatively narrow set of ags. I've never done the homework myself, but you can be pretty sure you can find an ag tire of the same height that is wider, but you will have to go with a different rim.

Having two tractors with 13.6-28 tires, I wonder why they only went with the smaller version of the 28s. But the front tires are a great choice. Run R1s on all my tractors. Nice tractor.
