Question

I have a 2005 nissan murano and their is a whooshing noise coming from the front end when i reach speeds between 30 to 40 mph, so i took it to a nissan dealer and told them about it and they checked it out and the final results was that i needed a wheel hub bearing in which it was replaced,it still makes that noise and the technician had to call nissan tech support and they told him it is probably the cvt transmission which is a new transmission that they are putting on some of their models, but although i am not a technician i have this outside gut feeling that it could be the tires, and i just had them rotated for the 30,000 mile checkup. the tires on my murano are the goodyear eagle p235/65r18104t.I love the car but that noise is very annoying. please give me an answer. thank you
