Ages ago I greased up the thread with LM grease and wound it up and down several times. Hence when I had the new front tyres (Uniroyals) fitted after the puncture incident, and I wanted the old spare back in the cradle, Mr National Tyre Man wasn't happy during his halfhearted attempt to shift it when he got mucky grease all over his nice clean latex gloves (!), said "well, if it's stuck I can't do anything" and WALKED OFF
My girlfriend said she saw him mouth something to the reception guy on his way through to the backroom too. Jobsworth.
I'm pretty sure I crossthreaded it, but haven't had a chance to look at it due to another problem with the car (another story).
Cheers,
Mark.
