I would like to get rid of my run flats but only if I can have a spare onboard. Will cutting the sub floor have any negative side effects, like sound insulation, structural strength, etc? I've never looked at that area very closely. It's awesome what you did, thanks for posting.
Thx! And that’s exactly why I did it. No more runflats. The car is a dream to drive with regular tires. To your questions. I would buy the bmw wheel and tire because the after market ones I’ve seen are too large. Everything else you can get on your own and save a ton. The subfloor is a thin layer of pressed fiber. I doubt it does much in way of sound deadening. In fact I would bet the tire eats more noise that what I removed. And most of it is still there holding the tire in place. The trunk floor is actually pretty stiff but I plan on throwing one of those EVA gym floor squares between the wheel and the trunk floor to tighten it all up and give support.
