Old post but thought I'd post here since I've experienced the same humming sound on new Continental UC6 tyres fitted on the Nissan Almera. I've used Toyo CR1 before (new tyres) on Ford Focus and there's no humming issue at all.

I am not sure if the humming sound from the tyres is due to the tyre itself ie. swollen, hard rubber of the tyre, or something else that is contributing to the humming sound not related to tyres. When I experienced the humming sound from the new tyres (Continental UC6) on the new car, I brought it to the service centre to complain. The wheel bearing was checked and reported to be not the cause of the humming sound. Then, the vehicle was sent to the Continental tyre shop, arranged by the service centre representative. Several checks and test drives were carried out by the tyre shop which including checking the thickness of the rubber and balancing, swapping all 4 tyres around rear to front and front to rear etc. In the end it's a futile exercise as the humming sound is still there. In summary there is no solution so have to live with the humming sound before the tyres are all worn out and replaced to new tyres. Hopefully the humming sound will be gone after replacing the tyres to new tyres.

The humming sound only comes up at around 30km/h to 80 km/h, and only on bad or rough surface roads. On good condition road surface it's silent or very soft humming sound. The humming sound gets loud only when the vehicle travels on certain road surface where the bituminous surface is rougher or worn out.
