Clemens, with respect yours are the standard size (a lot smaller by 6.85mm) but the very Limited Edition Morgan Lightweight Alloys have a totally different sizing hence the OP question.
They are 7" X 16" rims so larger than the standard 15" and with the deep section tyre wall combine to give a better ride than the smaller wheels, I had a good comparison with my first Plus 8 on 15" alloys.
Only optional for the Plus 8 cars for a very limited time in the late 1990's and look like this, they were a £1674:38 option according to my cars original invoice supplied to me by the previous owner.
