Hi all,

due to local road conditions I am planning to replace the BMW e60 tyre dimensions from 225/50R17 to 205/55R17. The 205/55R17 is not found on the recommended vehicle tyre dimension list.

The rolling circumference for the 225/50R17 is 1980.86mm whilst the 205/55R17 is 1982.37mm

In my case speedometer reading is not an issue.

Assuming that winter / snow tyres are “ideally” of smaller footprint width with higher side section height, there might be someone that might have been using this tyre size.

Does anybody have the experience / problem using the 205/55R17? i.e. iDrive warning, “false” flat tyre indicator warning, brake and driving control systems failure or warning; etc

Thank you
