Are they staggered? The Crevier parts guy on roadfly had told me they are (a few months ago), but tirerack is showing that the OE tires for Size1 (19") are all the same (255/50-19), but there are two sizes associated with Size2.

In build your own, when you check the 19" wheels in the options, then do a 360 view on the exterior, you can see that it removed the flares. If the back wheels wheels were 10" wide, they would need the flares, right?

I don't think my 335 rears are 10".

Edit: I just checked, he definitely said that they're staggered: http://bimmer.roadfly.com/bmw/forums...9484640-1.html Does anyone have the skinny on this one? [What's on paper vs my lyin' eyes...]

Edit2: This document says they're staggered: http://www.bmw.com/com/en/newvehicle..._catalogue.pdf Buuut, its an international catalog. It says we have LED coronas too.

Edit3: Dur -- how about I just go out and read the side of the stupid tires: 255/50-19 on both front and rear. However, I have a 35d. jcmd2003, can you check your 35is? Perhaps they went all European on it!

All this talk about how rough the 20" run flats ride has confused me. Seems ours rides nice and smooth. Feels very sporty but not at all rough. My daily driver is a Lexus GX470 and talk about soft ride. :D

Maybe take a tape measure to the tires - brochure says 9x19 and 10x19 but maybe it's wrong.

My 335s all have 255/50-19s on them, so they're all 9"ers.

I have to agree. I had planned to dump the Run Flats right after delivery, but I have noticed the ride is pretty smooth. I still plan to in October, I have a free set of Michelin Latitude Tour HP's in 20's waiting for me from Michelin but have not been in a rush to install them like I thought I would. I will just keep the Run Flats to Install when the Lease is up. I also ordered the Space Saver tire.

With 10" rear wheels you probably wouldn't need flares, definitely with 20x11 in the rear you should get them or it's obvious they are sticking out past the flat flares...

I just measured my rims, and the are all 10" wide (actually about 10 1/4). Perhaps you can measure yours and see what you get? I was told they were 9 in front, 10 in back as well.

jcmd2003, look at the size written on the side of the tires. The front should be 255/50 R19. The back would be either the same as the front for 19" or 285/45 R19 for 10"

New question - anyone have a factory trailer hitch on their 2011 X5? I have not seen a single pic with one and don't even see it listed as an option. Would like to see a pic with one as I will need it for a bike rack.

They are actually good for putting stuff (skis) on the roof rack :thumbup:
