Dumb wheel and tire question

[Uknown]

I have a MY24 Turbo S with PCCBs and Mission E wheels…which I love but prefer the 20 inch wheel ride better. I did some research before buying it to see about getting 20 inch tires and wheels. It looked like I could. However now what I am finding is Porsche Taycan Sport Aero wheels and tires are ok for winter tires, but not for summer or all season? It makes no sense to me. Does anyone know why that is? Anyone running these on a Taycan with PCCBs? Why would winter tires be ok, but not summer or all season?

Worse case I am going to try some all season tires on and see if the ride is any better (I don’t hate the current ride but the 20s on my old 4S was better ).

Are you sure 20s will fit with thr PCCBs?

Seems they do for winters, but not summers is what I am getting from 1 dealer and Sun coast.., I am skeptical.

The mission E wheel has grown on me, so likely I will just try some different tires initially.

But the lack of clarity on if the wheel works bugs me so hoping to find the technical limitation and understand what is different between winter and summer tire.
