Noise at 50km/h after wheel rotation

[Yabusa]

I recently rotated the wheels for the first time after 25.000km. Right after I started noticing a rolling sound at 50km/h. If I go above or under this speed the sound will almost disappear. Does anyone have an idea of what is going on? I discarded any transmission issues because I tried to put it in neutral at that speed but the sound is still there. The back tires that are now in the front are evenly wear out and almost new. And the ones that are now in the back have some wear on the inner side, which I think also from what I've read here and from the dealer, is normal due to the angle used for the front wheels, which gives the Kizashi that extra handling.
I'm almost sure that it has something to do with the tire rotation that was done but I would like to hear your opinions.
Thanks

Did you check the tire pressure? or did you do the tire balancing after rotation?

If I read correct this first rotation was done at 15,000 + miles.
I think the tires now have a set wear pattern thats causing
the noise you hear.
Most recommend 5,000 mile rotations.

Maybe excessive heel and toe wear? That type of wear is normal but if pronounced can create what you are experiencing.

If the tires were cross rotated try switching them to opposite sides.

Good Luck!
