Has 20.5x25s... I am looking at the 744s 26.5s thinking them might be alright for field use loading hay... I put 23.5s on my 544E & it made it WAY better & more stable.

 Picking 3-6 3x4x8 bales at a time now. 

Any  good ideas where to find a set of rims "reasonable"?  Might be buying a "Interesting" 6 bale head & want enough rubber on the loader.
