Vivekac: Good luck man, and good choice made with pathy.
yannick27: Your case is very clear with below two options:
1. If only vibration at steering after 110: Steering stabilizer need change
2. If you have vibration + slight wobble: Wheel balancing is out
I know i might sound stupid to you that after reading that 2 set of tire change and you still have this, but trust me about 90% of tire installing shops DONT BALANCE PRECISELY and that fraction of unbalance cause high speed vibration with little wobble.
Get to some real professional who do wheel balancing with properly calibrated machine. I saw one good shop in Deira few years back, but i cant recall its name and number. Its somewhere diagonally opposite Muraqabat Police Station (Behind metro station).
