Well it would depend on how you have your diff setup wouldn't it? If you have it setup properly, you would have the inside slightly spinning just enough so that the outside wheel has more drive torque biased to it. This is something I've seen from my own experience (albeit not in F1). This puts the outside wheel on its traction limit and the inside wheel basically just follows (although its spinning faster, its transferring less torque)
So, I'd still say in this case, the lightly spinning wheel on the inside is under much less "abuse" than the outside which "should" have more torque, more vertical load and more lateral load passing through it.
I'm happy to be proved wrong though. Perhaps in F1 with such a low CG, the inside wheel is still sufficiently loaded. Do you have any experience with this or some more details to share?
