Hi, our recently purchased X1 is proving to have a bit of a hard ride for me. It's has the M Sport styling and 255/35 R 19 fitted.
We need two new rear tyres and I was hoping for some advice on options for getting a more comfortable ride.
I know they are run flats and having had those before, know that they don't have much give in them.
Are there any options here please (that don't cost the earth!)

Thanks.
