Extremely pleased based on first few hundred miles of city/highway driving.
These Michelin runflats provide the handling that the original run-flats did, without any of the unbearable harshness of the OEM Bridgestone run flats, which I replace with Bridgestone non-run flats after a few thousand miles. The Michelin's ride a little tighter than the non-RF Bridgestones, but I haven't noticed any appreciable increase in harshness you often get with RF tires. My wife hasn't noticed a decline in comfort either. Note we have pretty bad city roads in San Francisco.
