Tire advise please !!!

[X54.8is]

Hi everyone,

I bought my e53 48is in march it came with set of winter tires and (looks like new) Toyo Proxes. When i bought the car, i notice tire noise little bit but not much it was reasonable after two month's i went to business trip and i haven't drive it for a month. After i came back from the trip i notice tire noise has gotten worse... i driven 7000 miles and when you go over 50 miles, you hear that haming noise come from back of the car, i had one of my friend to drive my car and i was on his car, when he passed through, i thought 18 wheeler taking me over.

Tires looks new and has good treads on it, but to much noise.

I wanna get some quiet tires, What brand of tires should i get?

Please advise...
