I'm ready to go with a TireRack set of wheels and tires 265/40R18 XL Michelin Pilot Alpin PA2 Blackwall N2 (Porsche). The 19" looks a lot less is certain. The amount of dry road travel is important; 95%.

Still looking for experienced feedback.

 

Everybody I ever spoke to told me that for winter tires you have to go with 18" rims, so your selection of PA2 18" is correct.

Only thing here - you can look around and find original Porsche take-offs - a lot of people sell original 18" rims after they upgrade to 19".

 

Is there good site you've used for these type of exchanges?
