Michelin PS3.

What is 'normal' to you? Would 40-50k km usage durable enough for you? If so then the PS3 is sufficient enough. If you want very high durability, then get something like Goodyear Duraplus which is claimed to last up to 100k km but of course don't expect the performance to get anywhere near PS3.    If you ask me, 40-60k km tire life is good enough already without needing to trade off much with performance. Tires that can last longer up to 100k km is only suitable for taxi! 

Not expensive lah for 15".

Even for 17", based on the performance offered, PS3 still consider worth every penny.

for 195/55/15 rm 230 ps3
try the hankook evo2v12 around rm 200

Try Hankook V12 Evo2, performance on par with PS3 though, review got from other user mention road grip is good in dry as well in wet grip due to its inner tread with double mark for water channeling efficiency
