Everybody has their opinion and stories, here's mine.
My car had 24,000 mi when I bought it and the OE Michelin ZP tires were decent. Worn evenly and nowhere near the wear bars yet. Noisy and stiff, wouldn't hold a line in a bumpy curve driven aggressively - didn't expect that. What really disturbed me though, they hydroplaned so bad I was scared to drive it in a steady rain! I chalked it up to the tires being farther worn than they looked, and I have snow tires mounted now which are far superior in every aspect.
Fast forward to a week ago or so, driving a loaner CTS with only 124 miles on Bridgestone run-flats. Same thing - fairly heavy rain and that thing scared me to death hydroplaning! 40mph on a 55mph secondary highway without skating all over the road. My ride home in my own car with snows on it was smooth and uneventful on the same road, same day. I honestly don't know who designed these tires or who spec'd them for our cars, but they must live in an extremely dry climate.
Are they all that bad? Is there a run-flat that's better rated for rain performance?
