I suggest you select a highly rated customization shop and consider their recommendations. For wheels, my shop worked with Forgeline and a Porsche master mechanic to design this staggered 21"/20" and flush offset Fuchs-tribute design with what I'm told were the largest rear tires ever fit to a Taycan with rear wheel steering and air suspension. They made this wheel/tire solution work with the Taycan alignment including four wheel steering, and they selected Porshe-spec NF0 EV tires with sound deadening, so everything perfectly customized for the peculiarities of the Taycan with sound insulated glass. Without a well-connected and highly experienced customization shop, I don't know how most car owners would figure out all those details.
