Where are the black tyres on all of Minichamps M1A2 wheels

?
Or have M1A2s(SEP) discarded the use of rubber tyres on its wheels? You know without rubber tyres the track would have friction and would probably snapped when braking hard.
Hmmmpf If somebody had told me earlier.....errr bugger
The wheels where the tyres are supposed to be are supposed to be painted black...
