Tires NANKANG or Achilles

Nankang NS-20, super easy to stretch and had no problems with them. also quite cheap (for the size i got them in)

Nankang NS2-R is best bang for buck track tyre hands down.

It’s marginally slower than most other semi-slicks, but it will last longer, it will be faster than any premium road tyre on track.

That being said, the CR-S is an incredible tire if your focus is driving on dry tracks. I found wear to be good with very consistent laptimes, it doesn‘t overheat easily, which is something I very much enjoy. Being able to push for many laps with the tire staying consistent and predictable is quite a treat if you ask me. Performance in the wet however isn‘t really good.

These tires wear like iron for me. They're fantastic.

The Nankangs are good

I have nankang econex on my 2006 twingo. But since i barely drive it, it's just fine.

CRS and AR1 are great track tyres and so use the AR1 myself.

However, what I think is their UHP road tyre, the NS2 is poor compared to Michelin/bridgestone/Continental offerings.

I’ve seen mixed reviews of them. With some saying they aren’t great in the wet(acceptable but lacking when compared to others), other saying they wear really quickly.

Just realized Carmax put a new set of these on the 2020 Mustang I bought from them.  Easily the worst performing tire in the rain that I have ever encountered.  Instant hydroplaning on concrete, when there isn't even much of any water.  At least knowing how terribly cheap these tires are, I may not feel bad replacing them before their end of trade life.  Dangerous!  Avoid!

Can't speak to an Elantra N, but on my GT86 they were very noisy and very uncomfortable.
