I was about to place an order for a new M5 and then discovered that it doesn't come with a spare tire or run flats
Just wanted to get an idea of anyone here has tried run flats? I know it is not good for performance but how bad is it?
Also, I've seen threads about keeping a doughnut spare in the boot. Is anyone doing this? How much space are you realistically left with? Would you still be able to fit in two suitcases and a baby stroller?
Planning to drive long distances and maybe on roads that may not be great and don't want to be stuck in the middle of no where with roadside assist hours away!
