The Taycan that set a 7:33 time was using a special Tequipment package that Porsche had specially developed for the Taycan to break the Nurburgring record that the Plaid had previously set, and it was running "R" type tires, Pirelli Pzero Corsas. So, comparably equipped, with the best available factory options for speed, the Plaid is 8 seconds faster around the Nurburgring than the Taycan. As for their tires being streetable, they are DOT approved for street usage, and can certainly be used on the street. When I lived in Southern California, I used "R" type tires on my daily driver; they were fun. Here in Colorado, they're not so practical since downpours occur more frequently.
