I had them on the Cades (NS2) that I bought for the e90. No they are not a premium tyre so should not be compared to a premium tyre.
For a budget tyre they are ok for normal road use. If you drive like a tard or have a very heavy right foot, then they won't do. But they will not see you off the road at their convenience.
Funny how people slate Nankang but say Kumho are fine, when they are in the same league, and the Kumhos are no better.
