Lu,
The bonding wire dangling from the landing gear may be fine in theory but I can assure you the last time I saw one of those was on a car for travel sickness!
As has been mentioned the tyres (as in Dunlop) are conductive.
As for wheel bearings I have seen them with some indication of burning but not destroyed as in thousands of volts.
As all of the ball bearing provide a contact, and there are fair few on them I would imagine that normal static just passes through without harm.
Worst case senario must be a lightning strike just before touchdown !!
