19 fills the rear nicely not the front so much.. But RFT prices on the 20s might be rougher not sure... But nothing smaller than 19s works on the F30..

20s have a very bad ride
19s are perfect!!
19s are perfect!!
From someone who went from 19's to 20's on my F30 literally in the last week...
I changed from 704M's with Bridgestone Runflats to 405M's with Pirelli runflats (both OEM).
The tyre profiles for front and rear stayed the same.(IE front on the 19's were 35, and the rears are 30) For that matter I think the width stayed the same too (225 front, 255 rear) making them look a bit thin for 20's, but nonetheless...
My personal experience;(validated by wife saying so too...)
Ride quality is pretty much the same. It's not harder at all tbh.:thumbs:
The larger circumference of the wheel allows the car to roll over things slightly easier and the ride is actually smoother.:thumbs:
The ride is definitely quieter (maybe due to Pirelli's) I drove back from Centurion to Fourways this morning with no tunes, enjoying the peace and quiet of the D and the open road.:thumbs:
I do find myself keeping an eye out for potholes more often. :skit:
I do expect the tyres to cost more.:thumbdo:
I do expect my ODO reading to be out.:fencelook:
I also expect some impact on economy. (but positive, as the 20's are actually lighter in my case, with them being forged wheels):thumbs:
The wheels fill the arches much better. :thumbs:
Refer to pics posted here: LINK
Other than that, it's been smooth sailing so far.
I suspect the harder ride comes from people going to 20's but then dropping the profile of the tyres to compensate for keeping the same circumference.
In summary;
I think in this case specifically, using the BMW OEM wheels as designed for the car had no trade-off between form and functionality. So I get the looks with now drawbacks. I know for a fact when I swapped my E90 335 wheels from 18 OEM's to 19's CSL reps that the ride was harder, and that the wheels were heavier, and that I had to alter tyre profile, and my economy took a dive (not that one should care about economy on a x35 car)
Anyways, hope that helps. I guess it comes down to what you prefer. Looks, functionality, or both. In the case of both, expect to cough up some more.

Back in the day when I had my 335, I kept the original tyres just changed the wheels, which had different offsets, landed up with a wider rear stance, end of the day also depends what wheel you going for to get the desired look. I kept the original rims and then gave them with the car when I sold
