This seems a silly question to ask, but has anyone any advice about removing the thin chrome wheel nut covers on a mini, please? I tried to remove the wheels on my mini 30 but couldn't get the covers off the wheel nuts (the only one that I could loosen was the locking nut!). I tried prising them from the base with a screwdriver and pulling them using a rubber grip, but they wouldn't budge. Because they are so thin I guess that trying to grip them to pull them off would be counterproductive, so any advice gratefully received.
Best wishes
Mike
