Here is a thread from Bimmerfest: Tire Hazard Insurance? - bimmerfest - BMW Forums it confirms the the plan is of value if you have the runflats. It also indicates that the Plan only covers BMW original equipment. In other words, if I were to put non-RFs the plan would not cover. So I am closer to concluding that if we must have the RFs, the plan looks worthwhile (and it still appears to be priced based on tire/wheel size and length of coverage). Equally, I am feeling that IF we can use non-RFs on the car, with no probs from BMW, that is a much less pricey way to go.
