A tire that is more stretched over a wider wheel will be more likely to "skip" over minute bumps on the road surface and lose grip in the process.

I think we're in somewhat agreement except for the fact that max steady state cornering force does increase with additional wheel width with TRA range. I wouldn't make a binary statement about any given manufacturer's chosen spot within TRA spec since a whole range of metrics figures into that choice other than purely maximum cornering force.
