I have stock A460 in my 1.6 Altis. They are noisy and hard. Grip is fine.
I would suggest to get rid of them and go for something else like Advan Db or Michelin xm2.
They maybe fine for 99% of the users. But if you have driven softer tires before you will never like them.
I have Advan Dbs in my other rides so I know how much inferior these A460s are in the comfort and noise zone.
