This is a follow up to the review I wrote a few days ago. My Cooper S came with Bridgestone RE050A RFT run flats and the ride was awful. I have just put these conventional Continental Extreme contact DWS tires on and the difference is huge.
1) The steering is now lighter when making corners at low speed and roundabouts
2) The roar from the tires is much quieter.
3) The Mini doesn't crash and bang into pot holes and ridges like it did with the Bridgstones. Don't get me wrong, it's not Lexus smooth, as the mini still has a sport suspension (i.e. firm) and large'ish 17 tires, but I drove the same route to work this morning over a section of badly surfaced road and I wasn't gritting my teeth and grimacing all the way. Sure you could feel the surface, but I now feel like the tire is part of the suspension not excluded from it.
4) Best of all, the tramling has all but gone. Its pouring here in Vancouver and worn inner city grooves in the road are everywhere, but the Mini now tracks straight and true, I can drive with one hand on the wheel instead of bracing myself with two and wrestling it in the direction I want it to go. Vast improvement - worth the upgrade for this alone. I noticed the same effect on my Mazda 3 sport when I changed from Goodyear Eagles to these Continental.
Based on experience in the Mazda, I know they will be good in the dry too, but I wimp out in the snow and leave the car in the garage so I don't have any experience of that.
