RunFlat and tire size

It seems that 18 and 19 inch run-flats do not get along well with potholes. It seems that the 17 inch standard run-flat does better. Is it a rim problem on the 18 and 19 inch? Is it the closeness of rubber to the rim?
Why the disparage?

Lower profile tires offer less ride compliance.

com·pli·ance
The action or fact of complying with a wish or command.

Are you saying folks who purchase an 18 or 19 inch tire are expecting a better ride? or perhaps assume that a bigger tire would do better falling into a pot-hole? The other possibility is that you used a wrong word-compliance.
