On my previous two E90s I go the RFTs removed and used the BMW mobility kit. I only had to use it once when I was in the middle of nowhere in the middle of the night (spooky) It got me home safely, but the tyre was completely screwed after, but that was because the puncture was in the sidewall, not the tread.
