before doing anything else please got to a shop for wheel alignment, since you have changed the tires & wheel profile you may need wheel alignment as well.
WOBBLING wheels at certain speed in PKDM vehicles after wheel changes are attributed to bad wheel alignment,.
am sure you are not an automotive engineer to challenge the assembly line & quality controllers of Pak Suzuki. At PW we always recommend never to change or upgrade any item in any Brand New Car for 1st 5000 kms so there can be warranty replacement for faulty items for free., if any.
regret your ordeal of making a hasty decision to upgrade tyres & change wheels.
