Rear noise

[Mark202]

Hi for the past year I've had this humming noise coming from the rear of my mk7 honda accord it started on the way back from a long trip to Scotland usually don't hear anything till 30 mph since then I've changed both rear wheel bearings and it's sailed through 2 mot's  but I still have this humming noise can anyone help?

Only other thing I could think of apart from wheel bearings would be tyres. Are the feathered or stepped on the edges as this can cause excessive road noise at higher speed 👍🏻
