Thankyou Hanno, that gives me some idea what is going on.

Wayne, your info both comforts and depresses me.

With the info you guys have given in mind, I expect the tyre shop won't want to have anything to do with my tyres, potentially on 'safety' grounds. Very nervous, some folk! Probably also quite wise.

I see my options as:

1/ Persist with trying to fit these tyres, via tyre shop in town.
2/ Return the tyres, and buy something new. ?starting same issue.
3/ Whittle down perfectly intact tyres, on the off chance I dont bollocks the job.
4/ Forget the whole waste of time, and cut my losses as such.

Now, I'm not a quitter, as my local tobacco shop will testify. These tyres and wheels only become mine once the set currently on the vehicle are returned, so I am loathe to butcher them. I will follow through with the run to tyre fitting place/s, just to say I have exhausted that avenue. I'll take advice from folks tomorrow, then contact the 'owner' of these tyres, for direction. I judge from my discussion with him today, that this problem has not arisen with him in the past. That is despite mating the tyres to other CMP wheels. I wonder if there were some of both types of tyres in his supply. Now THAT would be interesting.

I really, really, don't want to start lathing metal off my rims. Not because I fear weakness, but because I fear a total stuff-up from whoever gets the job. I know it sounds paranoid, but I have had horrendous work done by those who would have us believe they are 'professionals'......wink, wink. Had an engineering shop mill some metal from a block of aluminium once, and the finished product that was proudly returned, it looked like as I that big guy with the metal teeth from the 007 movies had gnawed at it.

Bet I dream about @#(ing tyres tonight!
