For the record the kerbing damage on my wheels was parking kerb damage, not the wheel bending high speed damage that they had insinuated in several messages to me.
I would recommend, as another forum user did to me but I was out of the country, to go to the dealer and "witness" their "test" and ask them to do the same test on wheels without any cracks.

I agree with the testing another wheel suggestion.
Also, they tested a cracked wheel and concluded that the run-out was due to the kerb damage, and the run out caused the cracks? I would suggest that the run out could be due to the cracks!
If they say the kerbing caused the cracks and your wheels are cracked on the inside (underneath the car) and the kerbing is on the outside - how do they conclude the kerb damage caused the cracks?
My conclusion is, again, they are not qualified to comment. Ask for the Regional Manager's engineering qualifications, particularly in metalurgy.
