I bought a new set of tires and the road noise was horrible. So I went back and the store replaced the tires (different brand) with a new set but there is still the horrible road noise. What else could it be.

What are the brands of tires? Your alignment could be out of spec and also causing noise. Same with suspension pieces.

Goodyear. Had the alignment done when I bought the tires.

If you had the noise before, it could be wheel bearings.

^ I agree, these cars are notorious for failing wheel bearings. I replaced the rears on my 07 x sedan
