I recently bought a set of three 15" Ronal LSs. When I compared them to a fourth Ronal LS I purchased to complete the set, I noticed that they have different center bores. The set of three have a bigger center bore and use a green hub centering ring, while the fourth is smaller. With the centering ring on they all have the same diameter center bore. The wheels are similar in every other way such as width and offset.
I was wondering if anyone else has Ronal LSs that use the centering rings?

Here is a comparison without the centering ring.
