@Doggo that's what I did. $ US 5200ish from Porshe dealer.Have been looking around at this and can't seem to find rims that work. Possible the ice macan rims are an option? Alpine5 and winter2 seem like a good choice of tire.
Worst case can get the OE 20" rims with (likely) alpine5, but it's like 6k delivered
great write up. For me 20s generally better in the snow than 21s. I have 21 summer and 20 winter wheels. Decided to go with winter wheel/tire cause we have tough winters with wheel damaging salt and gravel and I goOn my Macan 4, I have 21 " Macan Design 8.5ET27/10.5ET47. The best fit winter wheels I could find are from Braelin.
BR10 in 21" - F: 9ET30 gives -9mm inner clearance and +3mm extended wheel position; R: 11ET50 gives -9mm inner clearance and +3mm extended wheel position.
BR10 in 20" - F: 9ET25 gives -4mm inner clearance and +8mm extended wheel position; R: 10ET40 gives +13mm inner clearance and +1mm extended wheel position.
BR08 in 20" - F: 8.5ET25 gives +2mm inner clearance and +2mm extended wheel position; R: 10ET45 gives +8mm inner clearance and -4mm retracted wheel position.
I would have gone with the BR08 20" wheels to save cost on winter tires and I prefer to have a "+" inner clearance with a neutral wheel position.
In the end, as I leased my Macan that will see only 3-winters, I decided to just buy winter tires (Michelin X-Ice Snow SUV F: 255/45R21; R: 285/40R21) and swap tires 2x per season. My indy shop will remove/mount/balabce for $25/tire.
