potentially off topic, but the OE Pirelli are horrific in my opinion. A 235 PS4 has the same ground contact surface area as them due to the weird side wall angle. They're an absolutely bizarre tyre. Grip was shocking too compared to the competition. Again, all my opinion.
Whenever I had them on they chewed through to thread on the inside shoulder in 1k miles. 2nd set had all sorts of bulges and weirdness, blow-out waiting to happen. It wasn't alignment, and this is a common theme with them.
I went 235 square PS4 and never looked back. Pirelli, especially the OE flavour, has obliterated any trust I may have had in them as a tyre manufacturer. It doesn't shock me that "rim protection" (if you can call it that on those weird cross sections) is super inconsistent. Not one bit.
Also both should have the Audi OE letters R02 or whatever on the wall, so there shouldn't be any confusion.
