Tried to rotate my tires and found out that they are wearing out from the inside corner out, is this an alignment problem or something more serious?? I have the Dunlop Run-Flats 205-45-R17.
Also, can I go with a 215-45-R17 without any complications?

 

Your rears will wear more on the inside edge than on the outside due to the alignment set up when it is set to OEM specs. This is common on all BMW's and MINI's.

Front will not wear as much on the inner edge when set up with the OEM alignment specs.

As for going with a 215 -45-R17 that is fine it will actually make your speedometer slightly more accurate.

 

Thank's Shatzy for the info, had no idea!
