Honestly glad to be chatting with someone that is acutely aware of the batcrazy product overlap world of tyres and the borderline scammy nature of it in terms of pricing and region engineering.

Yes UUHP is another equally head scratching segment. I call that segment the ' sports car ego feeder' because honestly i have tried supersports on my weekend car and it's just not as versatile as the all around uhp ( max performance) segment i love. They take time to heat up, they are very focused just on pure grip and a bit scary in rain. If we lived in southern France ok la i guess.

Tyres have gotten very competent so that segment is diminished returns. Max Performance segment is just perfect.
It can match the grippy guys and still deliver near touring level of comfort and wear and not to mention weather proof in Malaysia and i LOVE IT.

China tyres have become better but they lack finesse and balance but I'm sure they will get there

Thanks for the tip on tyre shop.  But i think like you said MC7 supply is possibly being 'managed' in the market to create FOMO to those who don't really research well.

Another shop I can suggest is Oscar tyre in kota kemuning. Apparently they are cartel and they undercut almost all shops. Kl side ASO tyre is quite good.
Yes FK520 have improved A LOT in response. Falken is now on par with the Europeans i feel. They have pulled far ahead of brands like Yokohama, Toyo etc. I also like the fact they continue to produce FK series only in Japan. No brand dilution like Michelin and Conti by switching  UHP ASEAN production to lesser factories. I use it on another car in the household. Excellent.

Btw u know any good tyre alignment shops in KL area? I usually go to Kin Alignment is Sunway. Fella is good but expensive AF.
