I think Eco tyres are (relatively) dangerous.
It's not the car that's at fault, as such, but the low-friction tyres fitted to them.
We learned years ago that you drive like a nun, but my point still stands that you only regret fitting shit tyres when it's too late to realise the error in your ways.
Falken, I'd probably use - but Nexen and Federal are definitely not on my list of trusted brands.
