Hi Im looking to get a spare tire for a new rear bumper im fabricating. The issue is the current set of 4 rims i have are not manufactured anymore and therefore I cannot match a 5th rim to them for the spare tire. Would I just get a random rim with the similar dimensions/offset of my current 4 rims and then have a shop remove and replace the tire from that rim every time I rotate the 5 tires?

Ideally having a matching 5th rim would allow me to rotate in that spare tire by myself. But would like some thoughts on this. Thanks.
