Sure they are, Mike. They're Code 88 because they measure .088" front face to back face. That's
what "Code" means, nothing more.
As I noted...I hope...long ago in this thread, I refer to the NMRA definition of Code 88, Code 110 or any other code as defined in RP-25. While the NMRA Code 88 wheel DOES have a total thickness of 0.088", it has other dimensions as well, including tread size and flange sizes. All of these dimensions together describe the NMRA Code 88 wheel. A far as I know, no one else has published a different definition of a Code 88 wheel. I DID say that I would call a wheel having a code 88 tread with a Code 110 flange a "Code 88T" wheel to differentiate it from a true Code 88 wheel. Since it turns out that this wheel might not exist and is, in fact, a Code 110 wheel with a reduced tread so that the entire wheel width is 0.088", I'll use the term Code 88T to define THAT case a true Code 88 shows up sometime.

What you mean is that they are not an RP25 Code 88 wheel. You're right about that. IM wheels
aren't; Reboxx wheels aren't. Not sure about the others. What the IM and Reboxx wheels are, is
exactly what you said: Code 88 wheels with Code 110-thickness flanges. I've been noting that on
this list for at least two years.
Well...I glad someone is alert.<G>.
