Tires NANKANG or Sailun

I think it really depends on the car. A fresh set of 13” AR-1 will last 2000-3000km on track on my dad’s Caterham.

I have them on my '17 Bolt. They are definitely quieter than the previous tires. They seem to be holding up well, and I love hearing the tires chirp for traction when flogging it a 30 MPH!

Sailun tires are pretty good in general for being off brand. My Jetta had them when I bought it — I put about 45k miles on them before they wore out. And during that time I hit a pothole hard enough to bend the wheel — but the tire survived.

I was skeptical at first because they were so cheap. But after I did a cross-Canada trip on them I was so impressed by them. They survived nasty potholes. I didn't notice any range loss. Very quiet as well. The grip in wet conditions were far better.

I ran Ns2R on my R32 for a couple years and have no complaints.

I have them. I used to have a Michelin PS4S, which lasted about 24k miles before my front tires basically have no treads left (1.5/32 I think). Difference is stark, in terms of noise in highway. NS-25 is just so much quieter and I realized I can hear my podcasts without raising the volume to where it used to be. In terms or ride quality, I can definitely feel that it is ever so slightly more firmer than the PS4S, but I didn't actually check what tire pressure my tire shop put them on as, so it's subjective I suppose. road feel and grip, albeit I did not push them too much, isn't that bad.

Our shop puts on a fair amount of those Sailuns because people like the price point they carry. They generally hold up ok although the Terramax A/Ts 10 plys dont hold up great for anything bigger than a half ton truck.

The Nankang NS20 wears well on track and has oK grip, but in the past I've found it to have a somewhat tricky balance around the limit. GReat for learning how to drive, but again it's not the best tyre in the wet so on the road it might not be ideal.

Friends have run these, they are outright terrible in all respects.

I had a set on a 2008 F-250 work truck. Wore down quickly ~15K miles and unevenly. Felt like hard plastic chunks when cold, noisy, no off road traction. Had one blow out at about 60 mph and later on I had another tire get a tumbleweed puncture in the sidewall. They were trash. Swapped them out for a proper set of tires.
