[kostia]

Hi,
I have a 550i SP. I have found a 138 style rims 225/50/17 and I just want to double check that they will fit and I do not need to check anything else?
Thanks

Yes the 138's fit the 550i - If you have tire sensors (metal valve stems) you may want to check that the 138's have them because most of them don't.

Are you referring to tire pressure sensor?
