Get your wheel checked for any bends.
If the wheels aren't bent then it sounds like a typical case of smuggled tyres. Smuggled tyres can never be balanced perfectly. If you knowingly bought smuggled, then the blame is on you. Otherwise go to the tyre dealer and ask them to address this problem. Use any sources you have cause these tyre dealers are greedy scumbags who have no issue selling dangerous products that can prove to be fatal and will never admit their mistakes. For motorway travel, I would suggest to not use these tyres anymore.
