I would agree on how the car is used, would depend on which tire to buy.
I don't know how this sets with fellow forum members, and has probably been discussed before, but...
I thought the factory only recommends "N" stamped tires for replacement...yes, this probably adds $xx to each tire, but it has Porsche's stamp of approval.
Perhaps this is overkill for owners...because there are always exceptions, new rims, price, wider, taller, track tire etc.
