No, since they presumably have been on the car for a long time so you would have noticed a noise long ago if they were responsible for it. You said, or at least implied, that the hum began recently, and the only other recent changes you have told us of are the front tyres and a CV joint. Constant velocity joints don't hum, but tyres do, so I have no doubt that one or both of the new front tyres is the cause of the noise.
Have you tried my suggestion of fitting the spare wheel as a test?
