If I wasn't pressed for time, I would've made them get the run flats. But to be honest, it's given me something to think about noticing the difference in ride and noise. I got a good price too so didn't want to be too arsey.
Googling about though, BMW do sell a mobility kit (compressor and slime). Why would they do that if they didn't let people use non rfts. Probably more so that they prefer you to use rfts so wont give you the option. I know as a customer we expect to be given the choice since we're paying so much but sometimes though not giving a customer the option makes life so much easier.
'setup' for rfts, thats something I've not heard before.
