Are wheel adaptor plates allowed?

My buggy has kombi 5 stud pattern on the rear & my rims are severely buckled.

I have a few 15*7 early wide 5 stud rims & was hoping to use them with adaptor plates until $ start growing on the tree in the back yard!

ps. If anyone has a couple of 15*7 kombi 5 stud rims they don't need anymore..........
