big difference between 21" and 19"
 

Does anyone know if there is a big difference in E70 X5 between 19" and
21" wheels. Is the comfort still OK, I mean without the adaptive drive option, or is it uncomfortable.
Is the someone who did let go the sport suspension for this reason ?

There will be a ride difference for sure, and if you go with a wider tire on the larger wheel you will feel more road pull.

are the 20 inch wheels a bit more comfier than the 21 inch wheels? i have the ferric grey and mi thinking of switching to 20". these ones: (btw, the 20s remind me of the lambo Gallardo wheels)

i love the 21" ferric grey ones, but since my wife would be driving it, it ferric great attract too much attention, here is my car:

i want her car to be a bit more conservative instead of that rugged sporty feel, i just don't want other to think she "Wanna race" typa' thing :)

you know what i means?

i have an E60 M5 for that! :)

i can smoke ur m5 :P

20 vs 21 isn't going to be a real difference, the issue is the wider tire and smaller side wall.

issues in what sense? th 20" have slighly thicker profile, which should give a bit morr comfort. plusi like the 20" with those hexagonial type of design, plus they don't always look dirty like my 21" ferric grey! :)

btw, would the 20s change handling in any way as far as stability and handling since the rear tires are not as wide as the 21s?

i have 19 in wheels. i really want 20in. any good ideas where to find a good deal on 20in factory wheels.

i wanna go big like 22" or 23" like the hamann "flash"

You've been asking this for a long time. 20" factory (OEM) wheels are the cheapest from Morristown BMW. Check the "Accessories Forum sponsored by Morristown BMW" for their deal on it. I doubt you will find a cheaper price if you want to stay factory and not replica.
