Car shakes at high speed..tires are balanced

Haven’t moved tires front to rear, I think they are being balanced in the shop. I don’t think it is a bent rim, all the tires are on rims, and I didn’t hit any of them with a hammer. I haven’t noticed a werr werr sound of a wheel bearing, but I have noticed some occassional grinding noises in the back right tire. I didn’t think wheel bearing would cause it to vibrate.
