Resonating bass cabin noise when driving

Was there any conclusion to this? I’m driving a MG ZS EV Deluxe 2021, and suffering from the same problem..

If you're talking about the noise, the general consensus seems to be to change the tyres.
Personally I would just put up with it until ready for new tyres as the new ones may be just as bad.
In the past, for some of my previous vehicles, I have purchased tyres that are rated as quiet but been disappointed by the noise in the cabin as the noise rating is external drive by noise.

I have same issue. Rear bumper is hollow, and makes similar deep noise if tapped. wondering if that might be source.. Anyone get any further?

Just fitted the rear undertray brace to fix front edge but noise is still there. undertray still seems a bit mis-shaped!

Got the garage to properly fit the brace and now it is flush with no warping. Still getting loud deep resonating noise from rear wheels (2.6 bar, continental premium contact C) when they go over any uneven surface or bump. MG garage said there was nothing wrong but this can't be normal!!

I too. Not normal. Some recent mg4 hasn't this problem so I think something is changed

I also discovered that , I have not yet got around to looking at it. Also if you tap the rear quarter above the wheel arch on the opposite side to the stiffened charge port side, there is a hollow resonant noise to that. Taking off the interior trim is a bit of a fiddle , but hopefully it could access the inner surface to stick on a bit of damping material. Again, yet to get round to it .
