After a short test drive on the A3 I bought a BMW X1 Crossover with a load of extras from the local BMW dealer. I soon realised that the ride was very hard on the much cambered and pot holed side roads and that the car had to be driven carefully so as not to swerve. Now, after five weeks' ownership, we are very upset and cannot understand how BMW could produce a vehicle with such a hard ride. It has 18-inch alloys and low profile runflat tyres. When I checked the tyres before our journey I noticed that they were substantially under-inflated and wondered if this was done intentionally to soften the ride. Is there anything that can be done either with the dealer or mechanically to improve this worrying situation?
