This gels with my observations, I've seen raised dimple nuts, concave dimple nuts and security nuts with concave dimpled caps all on road wheels, as I said before, when looking at dimples trying to decide if its a cap or nut, then the dimples mean squat... just use the wrench to find out THEN use the cap remover if you have to, don't bother trying to remove a real nut with the cap remover cos you just end up with a broken cap remover.
