Wow, that seems strange!  It was my understanding that only very early TR2s
had 4" wheels, the steel wheel specification was changed to 4.5" at TS1869
according to several references.

I'm certainly no expert, but I don't think that's right.  My recollection is
that the TR250 wheels were 5", and the Moss catalog agrees.

Didn't the TR250 also have "Rostyle" hub caps?  That means the wheels will
have those extra long posts, something like an inch longer than the proper
TR4 wheels.  I don't know if the TR4 hubcaps will mount on them, but they
would look funny (IMO) if they will.
