True.
Consider yourself lucky.
If you get a flat, DO NOT go to a BMW dealer- they will refuse to patch it (which is what all MFGs allow) and will force you to buy a new tire...AND they dont offer a road hazard warranty on the overpriced replacement, so you will be vulnerable again.
If the tire IS non-repairable, DO, go to Americas Tire, Discount, Big O, whatever- pay less than the dealer AND get the road hazard. That way the next time you have 'coverage'
If youi pencil it out, all you'l have to do is replace the tires once and you will then be fully covered with road hazard (ie "tire warranty')
Also, you might try going to a local tire store and say "brand new car, new tires- will you sell me a road hazard plan for all 4 tires?"... Multiple people have reported success.

PS DO NOT drive around on your runflats if they lose pressure... pull over, get it repaired. Personally I would not trust a tire that had been run flat for very long....
