[4 Series Gran]

Hello All,
First time BMW owner here, just bought a 2017 Gran Coupe M Sport 420D.
While I really like the Car, the ride comfort on some bad back roads here in Ireland is terrible.
I read some threads on changing to go-flats, but there is limited discussion on how much of a comfort increase there is from changing, especially when driving on back roads.
Thanks in advance,
John.

Hello John,
Get rid of the run-flats and fit convential tyres, run-flats are worst type of tyre ever fitted to vehicles. The ride is much smother and better with a slightly wider wal. I recommened Michelin Pilot Sport 4 or Michelin cross-climate.
