curious as to why you didn't get a KUB rim....
..however you should be able to mount the 'tire and rim' to the 'center section' , FOUR different ways and one of them will give the same 'offset' as your right rear.
Why they asked about 'what tire' was to get the tread going the correct direction. The white rim should give you all 4 spacings.
Now the 'fun' is, did they mount the tire correctly. Did they have the original center or just the tire/rim ?
If you want an education......grab a Ford 9N manual and look at the diagrams on how to get 8 different 'track' (width) of rears..... as NCL said. ONCE the lightbulb comes on, it makes sense.

I didn't buy a Kubota rim for a couple of reasons. 1, my local Kubota dealer said it could be several days to a week out. 2, they aren't close to me. 3, the Ag tire shop said they could get me one. One stop shop was an attractive option.
I'm assuming you are assuming the center section can be mounted to both sides of the hoops. It can not. Only one side of the hoops have a flat landing allowing the center section to mate up. Therefore I only see 2 ways it can be mounted to this particular wheel, neither of which will match the other side.
The shop had the original wheel - they broke the old tire down before I concluded it wasn't worth reusing. It was thin. BUT In fairness I did take it with me when I left so they did not have it for comparison when they mounted the new tire to the new wheel. They asked which side it was for....hence the original question why would they ask that specific question rather than be concerned about the orientation of the original tire/wheel.
From the comments I've received here it is apparrant they goofed up. I'm hoping they will fix this on their dime.
