what experience u want?

My tyre size is 225/45R19.

Quite comfortable considering the 45 profile.

However, not many choice of tyres for this size

225/45 is still 10.1cm sidewall so still reasonably comfortable. Once you start to drop below 10cm then will feel a bit stiff, and below 9.5cm then will feel quite harsh.
Switching to normal ones will surely give you noticeable improvement in comfort. Btw how come you change tires so fast?? I thought not so long ago you asked and changed already, no?

I'm on 19" too, falken fk510 is indeed quite good between handling with comfort. If you want maximum grip, ps4s still the best choice.

BTW, what ride and what is the original tire size?
I believe we need more information to properly recommend.
As tires itself also got many different type from UHP, SUV type and also different width & height even for 19".
