I've never kerbed a wheel while parking, but I have had them kerbed by pot holes and, oddly, a large speed bump.
With regards to the bump, I was driving towards one that was flush with the kerb at the peak (and this went on for just about a car length), but not on the "inclines". I drove up it and realised the person coming the other way was trying to swing in to a turn, so moved over to stop our mirrors clashing/us crashing, and my nearside wheel drove on to the kerb itself just off the edge of the speed bump. It must have been fractionally so, as I sort of "popped" off the kerb on the way down the bump and kerbed the wheel!
