Agreed, could well be the tyres, i've scrapped tyres (Toyo as it happens and other than noise/ride they were fantastic for wet grip especially), at 4mm due to ridiculous noise and harsh ride though acceptable when the tyres were newer.
You'll have too jack the back up and spin the wheels if bearings are suspected, but i expect road roar.
I've recently had to soundproof the back end of a couple of small cars, C2 and Aygo, the difference i transmitted road roar hads been remarkable, in both cases the thin plastic mouldings were the only covering over the rear wheel arches, both cars are transformed...might be worth having a poke nose under the boot/arch trim see if your rear wheelarches and boot area are similarly uncovered.
Road roar is a big problem, especially with low profiles, there are some tyres designed for quiet running.
