Tire sound from my 307 vehicle

I changed the tires of the 2004 model 307, which I bought 3 months ago, about 1 month ago, bought michelin brand energy series 4 seasonal tires. while my car is walking, there is sound on the front tire, there is not much on normal asphalt, but when I come to the asphalt asphalt, there is also 100 km and above but it sounds like a helicopter sound, I took it to the rocket launcher, he told me there was a mistake in the tire 4 pieces & nbsp; used tire tactic it seemed like there was no sound, but anyway it was not as it was before but it sounded like it was. I said there might be a mistake in the tire and they sent it back to the factory for the test, they said that there was no problem with the tires in the test. I did not change the tires & nbsp; front or back, but I did not change my cross but there is still that sound & nbsp; master said that there is no problem with the balls. aca ba this problem may be caused by & nbsp; why. ???? & nbsp;
