Hi,

I like your setup w/ the spare.

Can you say what size your spare and emergency rim are ?
Are your run flats on 18” or 19” rims?

I bought an 18” emergency rim, and was told by my BMW dealer service guy that
I can’t use the 18” rim, since I have 19” rims on my 540 xDrive, and if I used the
emergency rim, it could cause damage to the transfer case of the xDrive, and BMW
WOULD VOID ANY WARRANTY....I’m told the transfer case is a $9,000 item if it needed
replacement...

What do folks think? Should I just forget equipping the car with the 18” emergency rim, and get a full size 19” rim to use as the spare ?
