Can't really judge simply by the thickness of the sidewall. Besides, the sidewalls are not really 110mm tall. That includes the actual bead of the tire that sits below the lip of the rim. about .75" of tire sidewall sits below the edge of the rim so the sidewall above the rim is more like 3.5" only.

Furthermore, how firm the sidewall is has a much greater impact on how the car handles, amount of sidewall deflection, how quickly the car turns in. For example, Formula 1 cars run these super thick sidewalled F1 tires and these cars probably turn in sharper and handle better than any other cars on the planet.
