I have an 04 Titan LE, 110k on it. Once I hit 40 mph all the way upto 55 mph I have a lid humming noise, it doesn't change if I drive straight or turn, just constant between those speeds. I'm figuring it's my tires, I have cooper ATPs with about 30k on them, as the tread is wearing I'm getting more road Noise. Anyone experience this, and what did you find. Front and rear diff have fresh oil, no axle seal leaks. All suspension is sound and new.
I have the same tires and I hear mine from 20,30mph to hwy speed and hear it get a little more pronounced when I take a corner... I keep thinking it's one of the front wheel bearings also, but it drives fine. Very odd to me.
