Cool , but way too silvery .
Look at modern , in use construction machinery for reference .
The steel alloys used for Tiger wheels and modern equipment are a bit different but neither would polish up shiny silver .

It's amazingly difficult to find good photos of bulldozer / excavator running gear surfaces on Google Images ,
but the steel is closer to the darker , graphite gray or umbers from the unavoidable oxidation of the freshly worn steel .
The topside of railway track will give the most polished surface appearance out of steel on steel conveyance you'll find , but you have to take into account the fact that it is stretched out straight and providing the ideal angle of incidence for lighting to make it shine .
With scale models you need to compensate for the vast differences in the effects that lighting has on a scale subject and a real one .
Even though certain wear points of a full size machine may appear shiny to an observer in real life , that point-specific observation is impossible to convey in scale .
This photo below demonstrates how the return rollers appear very bright in this viewing angle but if the camera were repositioned only slightly they definitely would not . It's only due to the perfect angle of incidence of the lighting .
