But the load spec for Macan differs by 2 between front and rear 101Y front 103Y rear for size 21 wheel.
I read somewhere the different N criteria were just the moved up through as later tyres of the same name got approval. i.e start off with N0 then N1 then N2
However when I look at Blackcirles only N0 available for front 21's but for the rears No, N1 and N2 available for the Michelins with N0 and N2 having the Macan 103y rating but N1 107Y implying to me a fit for a different Porsche model
