I think FK510 can be cheaper than V701. This is based on the pricing of the previous FK453 model and because I never heard/seen Yokohama cheaper than Falken for similar competing models but I can be wrong.

RE003 is strong in the dry and reasonable/decent in the wet but the tread wear is only 220 and already confirmed will finish faster. The compound is not easily chipped though, similar to my CSC5 which only chips a little bit so far as opposed to PS3 or F1D5 which are chipping a lot more.

Kia & VW? No thx bro, I don't have confidence yet in Korean cars and also in VW. Furthermore, those are big cars. If I were to change, I would want smaller, more agile, and faster, don't want as big as my X anymore, AWD turbo with simple manual gearbox would be best. Anyway economy is tough, no money to spend on fancy cars coz got other much more important priorities.

Ic, from some other forum, it seems the wear is faster than usual. Maybe you don't drive aggressively in the corners, hence the wear is slow? But the 220 tread wear rating is correct and supposed to indicate it should wear out faster. Other competing tires usually have tread wear rating of around 300.

Yes, PS4 should be better in the wet grip and aquaplaning resistance than RE003.
