Your Kubota salesman can order rim and tire together under Whole goods cheaper than parts. Give it a try.https://www.orangetractortalks.com/forums/threads/whole-goods-vs-parts.67345/
Ordered the 2122654 from TSC 3/19/12 and picked up on 4/6/12 . When we got the tiller unloaded and started to assemble we found it was shipped with wrong parts! And the wrong part had a big X on it as if to say so.
