Precisely, it depends on the surface, hence why modeling this can get complicated, different surfaces interact in unique ways.

Here's some reading that went way over my head that may help understand friction between rough surfaces: https://workspace.imperial.ac.uk/med...20surfaces.pdf

Why make them do it? Most teams have the resources to test this ourselves. Perhaps we'll do a study of this and publish our results.

You can simulate this without buying huge wheels, just use a pneumatic wheel and test it at varying levels of inflation, the under inflated wheel will likely have better traction in accordance with your theory.
