I've heard what you are saying before by others that have had runflats. The Contis are runflats and are probably quiet because they are new. The Bridgestones were quiet when new also. Your right I wouldn't buy a set but if they're going to give me a new set every 8000 miles I'll take them. Or they can give me non-runflats, a spare, a jack, and tools since the new cars don't come with any of that.
