Well, surely these are the same. Right? Haha of course they are. This is silly. Right? RIGHT?!?

Just because it’s spinning more does not mean it wears out faster though.

Maybe tires are more resistant to rolling on curvatures?

I'd say they are less resistant to going on positive curvatures. It's like a bum that goes deeper into the tire, deforming tire more which should result in more wear than driving on even surface.
