Arkin, I have i20 OE alloys on my i10. I have also upgraded the tyres to 185 60 R14 which is a perfect match to i10 stock tyres. The ride quality is much better with the upgrades. Plus, there is road noise reduction and better grip (experienced when driving on highways during rains).
I would suggest swap the i20 alloys with the i10 rims + upgrade the i10 tyres to 185 60 R14 (Yoko A-Drive/S-Drive - performance tyres or Michelin XM1+ energy).
