Tires OEM Audi or OEM Porsche

My car on 15x8's is sporting 195/50 15's and the tires are slightly stretched-- not too stretched in my opinion but just help to round out the sidewall a bit

Had an alignment done at a Porsche dealer here in TX, gave them a printout of the specs a shop in CA had aligned it to. Come to find out they were way off and I ended up destroying the inside edge of my front track tires.

The stock tires are garbage. Brakes are expensive.
