In 7mm, I tend to use Markits rolling stock wheels, which are cast metal with a small insulating bush. I notice that Roxey Mouldings sell a 4mm version from the same maker, gauged to 00, and I wonder if anyone has successfully used them by sliding them out to EM? They are supplied on a 26mm pinpoint axle, but I’m afraid I know nothing about the flange profile, nor the tread width (which does look a bit on the generous side).
