Wow, I just took some spectra tapping on different surfaces, which BTW is a very good way to spot resonances that would amplify road noise. My wheel wells don't, fenders don't. So far a very strong suspect is the frunk liner's tall vertical wall that faces the cabin. It's a perfect drum. The spectrum also matches up well with that of the loudest rumble I got inside the cabin at highway speeds, so it would likely contribute.
Lining that with any kind of adhesive rubbery schtuff until it's deadened would likely help. Removing the frunk "tub" is pretty easy, but if we just stick some material onto that wall without pulling out the whole assembly we won't really lose frunk capacity and we can evaluate the effects, and maybe do a more permanent job if it helps. I'd guess the trunk tub also has some drum surfaces, that's next to go tap on.
