I was a repeat user of Nexen N8000 until they stopped production.
Currently using Hankook Ventus V12 evo2 (Korean made - 215/45/17) and still loving it until today!

Generally, not necessarily to go for US premium tyres but ideally avoid China brand tyres if the price is not much difference.
Alternatively, if I on budget may consider Kumho Ecsta PS31 but not made in Korea though.
