I've run a set of the N8000's on the ZT-T190.

I currently have a set of Goodyear F1 As2's. The Nexen's were comparable performance IMO, and half the price. Can't comment on how long they last mileage wise in comparison, but personally I think the N8000 are superb value for money. They are 90p dearer per tyre though.
