Has anyone dumped his/hers runflats on 20s?

So how was it at 145? Can't wait to get there myself when I take delivery!

it was effortless. the X felt very composed and safe. However, at such speeds, wind noise becomes quite apparent and a little bit annoying. Otherwise, it was perfect!

Sorry to bring an old thread back!

But, after having switched, last Spring, to Michelin Latitudes Tour HP for my 20", I have decided to switch back to my Dunlops (Which are in my garage still). Let me explain why:

At first, when I had them put on, I noticed an immediate improvement in ride comfort. However, after having driven it aggressively, i must say that they are no good for the X's capabilities. The steering feels a lot lighter, the on-center feel is not the same, and you have to give more steering effort to turn. The DSC seem to kick in a lot more therefore constraining the power delivery. Even on even surfaces, if I floored it and tried to change lanes at the same time, the DSC would engage and not allow for any acceleration. Needless to say, you can forget about even increasing speed while taking those long-turn on-ramps, as DSC would prevent the fun yet again. I was thinking that maybe the DSC software could be upgraded, but no luck with that. I also played with the tire pressure, but no improvement.

I also noticed that the Michelins are rather noisy on concrete highways: all other surfaces seemed very quiet.

Additionally, they are not as wide as the 214 style wheels, which makes the X look less aggressive.

Anyway, sorry for a long write-up, but I really thought somebody may benefit from this.

I must say, that after almost 7K miles, the Michelins look like new.

Does anybody have any thoughts or other experiences?

Thanks

I'm in an almost identical position. After about 7K miles on the Dunlops, I switched to Mich Tour HP non runflats - initially liked the improvement in ride quality, but over time it appears to be offset by other sacrifices in looks, handling and noise.

The Michelins (esp. the front tires) don't have the same tread width as the Dunlops, so they look a little weak. We're talking OEM size, identical to the original 20" Dunlops.

Regarding noise, agree that they can be very noisy on certain concrete road surfaces (very common here in Dallas). Also, on any type of road surface, at speeds above 80 mph, the Michelins begin to howl. I've tried various inflation pressures to see if it helped - it didn't.

Bottom line - when they wear out, I'm probably switching back to the Dunlops (or any better alternatives that may be available at the time). One positive for the Michelins is it appears they will last much longer than the Dunlops. I'm guessing I'll get close to 30K miles out of the Michelins. I'd be lucky to get half that out of the Dunlops.
