Tires OEM BMW or NANKANG

I had a set of Nankang NS-25 UHP tires on my mazda 3 turbo sedan. They were great tires and handled really well. Got about 30k miles out of them. I was pretty pleased, they even did alright in snow.

So to create some perspective, my AR1’s on a small light car (Miata), lasted for 5 track days. Assuming an average of 20 mins per session, and around four sessions in morning and four in afternoon, we can assume I’m doing around 160 minutes or driving per day. So in theory I put 13 hours on those tyres!

I’ve used Nankang plenty of times on my older cars, they were fine. Drove fine in wet, drove fine in dry, no louder than any other tires.

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 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.

My buddy has them on the rears of his FBO 335i right now. They're not terrible for basic to spirited street driving. They can't handle any power at all though.

I've had NS-II on my car for the past 4 years. For daily driving these tires will do just fine. Wet grip is alright and they're not terribly loud. They don't compare to Michelin Pilot Sport tires I ran before but they also don't cost anything close to Michelins.

I have a set of 215/40 18 nankang ns-20's. Tires of course are on the cheaper side but many run them so thats what I went with. They perform fine for daily use and ride alright, however a few months back now I noticed that the driver side tire had some (at the time) small cracks in the sidewall. Thought thats odd but didnt have means to buy new tires so kept driving on them. Of course it got worse and then the passenger front tire began to do the same. This week I threw on a set of steelies and inspected all 4 tires and they all have the same sidewall cracks. The rears not as bad as the fronts but still present. Mainly on the inside of the rear tires, outside and inside of the front tires. Rear tread id say is like 60-70% remaining while the front are maybe 50% or so. Tires are also less than 3 years old with maybe 30k miles. Super frustrating as I have no idea why they did this and are pretty much trash at this point.

Those tires are death traps in snow and ice. No sipes, no studs, hard compound... You're going to be on hockey pucks.
