Default Wheel Size Selection 20 vs 19

I like the look of the 19" Turbo wheels the best, but on my build I have selected 20" SportDesign wheels (which seem like a bargain at $1260) thinking that I did not want to give up handling. I have selected AS+PASM and PTV for that reason as well.


I am still second guessing switching to the 19" Turbo wheels. I would appreciate some other thinking on the issue.

The appearance is your call, but we have the 20" Sport Design wheels because they are so easy to clean and we are anal about keeping them clean on the inside. We also love the appearance, but that is just an opinion.

The ease of cleaning the wheel is a good point.

The 20's are also a bit wider in the back!

The 20's will get you the 295mm rear tires which look outstanding. I also like the 19" Turbos for looks and ease of cleaning. Another pro for 19 inch rubber is less expensive tire replacement costs. I went Spyder 20's, SD was choice number two and the Turbo pulled third place.

Whether the 20" wheels offer any performance/handling advantage is probably debatable. Viewed from the side, I really like the 19" Turbo wheels. What made me switch to 20" SD wheels was the view from the back, where the 295mm 20" or 21" wheels look just fantastic. I guess one could much of that effect for little cash with some 1" spacers.

Handling/performance wise the difference between AS and summer tires is probably much more significant than 19" vs 20" wheels (265mm vs 295mm width).

@Cloudplay While I agree that compound is a bigger difference, 120mm more rubber width on the road is a significant difference as well.

19" rear is 255mm while 20" rear is 295mm, a difference of just 40mm which is still quite significant.

However, 19" with summer tires may perform equal to or even better than 20" with A/S tires.

I don't think that bigger-is-always-better as far as rims are concerned, neither for appearance nor for performance. However on my build I went for the 20" SportDesigns rather than the 19" Turbos for a few reasons (as mentioned by others as well):

1. To my eyes the SDs look much better than the Turbos - more classic, less fussy.

2. You get the wider rubber, which looks better and might give slightly better grip.

3. They'll be easier to clean.

4. As the OP said, the upgrade isn't too expensive.

By the way, when I get my Macan I'll be getting the 20" SDs either powder-coated or painted in Satin Platinum or Dark Grey. I don't want black because others have pointed out that black tends to make the wheel's details become less visible. The Platinum / Dark Grey should go well with the body's Dark Metallic Blue and other black trim.

Anyone looked at weight differences between the 19 and 20s? That's also going to be a performance factor if we are spitting hairs.
