Actually I don't disagree.
No problem, we can look at the whole tyre, but lets focus to all capabilities in dry and wet, because noise, fuel consumption and wear do not directly relate to road safety which we are talking about.
Dry road: 2.0
Wet: 2.3
That places N8000 before Semperit which is in 7th place. So 7th out of 19.
If poor results are mainly due to excessive wear and not due to being unsafe, then it is the least of my concerns as I will be probably changing tyres after 4 years because of the age, with enough of the thread left.
On the other hand, somebody else who spends a lot of time in his car (maybe even different, more comfortable car) might be mainly focused that the tire lasts long and that its quiet and so on..
So as I said, I know these tyres are not the best if we are looking at the whole package, but considering just the safety, according to adac, they are not bad either.
