Road noise in my vz2 hybrid is pretty bad too. T005's from factory, 16k miles in.
On the M11 it's louder than my 2001 hzj105 landcruiser - and that's quite something. Given the lc is on bfg ko2's 285/75r16 that have done 50k miles, running off a 4.2L donkey diesel engine.
I would even say, the road noise inside the formentors is about twice as loud as what's going on inside an XC60. The Volvo is very nice, the
formentor sounds like a wind tunnel.
It's not the soundkator, because the hybrid can be driven entirely on electric,.and the sound persists. It's road noise. Unfortunately I have only driven two formentors, both hybrid. So I don't know what the situation is with other models.
It feels like there is more to it than just the tyres, it definitely feels like some of the formentors have sealing issues or leaking/poor insulation.
