My understanding is that tread width is ultimately most important with regard to DSC? But, I could be totally talking out of my A** and happy to be corrected!
Not sure about DSC, or DCS, or whatever it is, but when it comes to the driving dynamics, as pertains to oversteer and understeer, then yes, the TW is very important, and .1 is negligible.

However, RAKE is super important to some driving systems, so choosing a taller sidewall in just the front or the rear can have a terrible impact on how the car loads each tire, which can confuse all sorts of systems.
