Replaced OEM runflats with these tires. Ride comfort and wet traction improved significantly. Tires are fantastic in rain and light snow. Haven't driven in heavy snow yet.
As other reviewers have warned, the steering response of these tires is much slower than runflats. Entry into turns has lost a lot of precision. This does take some of the go kart handling fun out of the Mini. I considered returning them, but the improved ride comfort has been worth the trade off.
