What did the Panther's interleaved road wheels achieve?

What practical benefit did the Panther's interleaved road wheels provide in return for their maintenance burden?

They promised a smoother, more stable gun platform and better fire on the move, but the vehicle did not realise that benefit well enough to justify the complexity.

The viewer uses the Panther tank's interleaved road wheels as an example of technical refinement that more than doubled maintenance work. The intended payoff was a smoother ride and therefore a more stable, accurate gun platform, especially for firing on the move. In practice, the Panther did not realise that promised mobile-fire capability well enough to vindicate the complexity. The same standard applies to warship engineering, where an improvement must be judged by operational gain as well as theoretical performance.
