Sorry Fred , I called my Son and ask him cause he put them on for me , but it must run in my family he can't remember either. He said to me you know how many rims I've measured since then . Now I don't feel as bad ...lol
If you still have the receipt for the wheels that should tell you. I have a file on my car for everything I have bought for it. Even the smallest thing the receipt is in there for the next guy.
