Get it balanced from Honda Fort. I had similar issue. I got the tyres balanced from Honda point, honda defence, cavalry honda and another place but none of them could balance the typres properly. Steering would slightly vibrate at speeds over 100 and vibration increased with the speed. Finally went to honda fort and the problem got fixed after 2 years. I almost got my Axle changed in order to fix the issue.
So go to honda fort, find ghafoor sb on the third floor. He will do a test drive and let you know what the issue is.
