Thanks Jack and welcome to OTT. I actually started a thread on this very topic and you can find it here:http://www.orangetractortalks.com/forums/showthread.php?t=2886 The rears should be very easy to find even if you need rims. It's a very common lug pattern and size of tire on even brand new kubotas. The fronts could be a little tricky. Hope this helps.
