Good luck convincing BMW that run flats are a bad idea. It lets them save the money of equipping every car with a spare, a jack and a lug wrench. They're not going back, ever.
Goodyear makes awful tires, it doesn't matter if they're RFT's or regular tires. I've had regular Goodyears bubble sidewalls even with very small impacts.
Our 135i is on non RFT's and works much better than stock. When we buy our next BMW, I'll likely jettison the RFT's in the first month.
