Just change PS4 for my countryman, I think the problem is not the type of tyre, it is on Mini.
Drive alone is fun, but with passenger, they will feel uncomfortable.

Before that I used PS3, I feel that PS3 more comfortable than PS4. But that is only like first 10k km, after 10k km the comfort and quiet gone, become noisy and a bit bumpy. But the grip is always perfect.
