I would think that the vibrations do not come from rft tyres as such (if not damaged to some degree) nor from spacers. The cause is somewhere else. I would first try rebalancing with road force, that would reveal potential problems with rims and/or tyres as such.

Hello, my idea is also tyre balance road force based. But my tyres are very old designs. 2021 made but completely away from premium quality and comfort.
bridgestone er300 turanza. Very hard and loud. That's why cant reach low road force
My latest hope is Michelins.
