Tires are the only contact that translates movement for your car to the road and can mean the difference between you having an accident and avoiding it. So think about that before you go and buy some cheapo unknown crappy tires.

No, I'd rather buy a good used well known tires than the unknown cheapo brand you mentioned above! Heck I wouldn't even use it even if they were given free to me!

Still, I can physically inspect it to judge the condition and I would have no doubt of the original quality of the brands. So if you tell me to drive over 200kph and whack sweeping fast bends say using a used GY F1 vs using this Cromax or whatever the heck it is, no brainer I'd still take that used F1 anytime any day (provided I've inspected them properly and happy with the condition).

Well it seems like you've never driven with very good tires before, or maybe never slip and slide due to some shitty tires. Many are like you thinking a tire is just another piece of black round rubber/latex and they are all the same. Yes of course there's part of the branding value there but there are also a lot of technology built in and developed into this piece of black rubber. I tell you, tires is part of the car that can improve your handling characteristics the most or vice versa. Try driving and cornering with some shitty tires like Silverstone or this Comax or what ever Vietnam & China brand tires and compare that with a high performance Michelin, Goodyear, Bridgestone, etc2. If you still cannot tell/feel the difference then I cannot say anything anymore.

No, not true. Who says that? I'm using Goodyear F1 for >3yrs now (>50k kms) often very hard/aggressive driving, pushing them in the corners, driving >100kph in the rain, often cruising at >180kph constantly in the dry. They serve me well and does not disappoint me. It's a no brainer, choose the Goodyear instead of that unknown comax.

Well as I said earlier, my current GY F1 is already >50k km without able to do rotation coz I'm on a staggered setup? But yeah, my fronts are looking pretty much destroyed already now.
