i have 2006 exi
with 205 60 r 15 tyres
suspension felt a bit harder as compared to my previous car city idsi 05
i checked with many mechanics they all told its fine.
1 ov them suggested to have a thorough underwash and then sparay wd 40 on suspension rubbers.
i ve done it . now my car feels a bit better but not as much as the cars with oem tyres and rims
so i think that culprit may be my stock rims.
Sir you are using more then an inch bigger tires then stock diameter, they are even bigger for a VTI.
You should change the tire size to stock 185/65 R14 and some premium tires like Bridgestone Turanza GR 90 or AR10.
Else if you need low profile get 195/55 R15 and Yokohama S drive.
Your current tires will ruin your car's suspensions.
