WHich other gen 5 Prius has the same donut wheel bolt pattern so I can buy one?

Here's a comprehensive list:

100? Gen 5, man.

 

For the OP, there's a thread by @Hammersmith that has a lot of stuff in it. I got the part numbers for a new oem wheel and jack and bought a tire from Tire Rack. A tad more expensive I'm sure.

You didn't mention your model. I went with putting it in bag with a black winter coat on it behind the passenger seat on my LE. I felt I'd lose trunk space if I put it in the well. AWD and higher end models have a higher deck, so tire in well more doable. Still work to do.

edit: If you wanted to, you could probably fit a full-sized spare in back of the passenger seat.

 

Gen5 are NOT 5x100; those are gen4's
I believe gen5 is 5x114.3 pattern, same as Subaru 5-lugs.
