Porsche tires.. a world for itself??

Hello people, I’m not driving a porsche, but I’m already diligent. nevertheless I have a question: wanted to buy me new matures, unfortunately not for a porsche and I came across the porscheidentikation n4. the other dates like wide/… are all right. the matures are from pirelli, 265/35/18 asymetrico or something. pirelli has the same matures only without a porschecode. well, I wrote to the nice Italians and want to know what differences there are between porsche and not porsche they just said that I can drive the size but that they don’t say anything about the mature composition. my fear is that the porsche tires have a softer rubber mixture. that’s great for the driving behavior, but it’s faster. and you know how expensive the dinger is… so my question is if anyone knows the difference between porsche and not porsche and if the porsche tires are recommended??? many thanks already in advance
