If i am going to change my 04 e60 wheels by replacing the 2003 M5 wheels, does anyone know if 2003 M5 has run flat tires because now i do have run flat tire on my wheels?? please advise

 

1. No the E39 M5 does not have runflats... but thats the LEAST of your worries...
2. The E39 M5 has a center bore of 74.1mm where as the E60 and many other BMWs have a 72.56mm center bore. I mean, it'll fit but you have 1.5mm of free play and will most likely cause vibrations. Either that or get hub centric rings to correct the problem.

 

A e39 M5 wheels will not look nice on a E60 it will be outdated. But that up to yo what you what.
