The care has the same problems with both dimensions. I must add, with the summer tyres the car is running perfectly normal and smooth. I've occurred this problem only with winter tyres on.
Can anybody please give me some answers? Thanks!

When you say 225/45 R18 "all wheels", are they on 8" rims, or on the 8"/8.5" rims?
If on 8" rims, difficult to say what is going on (assuming xDrive transfer tolerances), except pressure variation (F to R) possibly too great. On 8"/8.5" rims, could be pushing the RC tolerances.
I'm assuming all tyres are the same brand, type and spec.
