If you*ve recently gotten new tires, they could be the culprit. Some tires are simply louder than others. If your tires aren*t new, check to see if they are wearing unevenly; if they are, you most likely need an alignment.
Keep in mind the noise may not be the tires at all - bring your car into a repair shop so they can check your wheel bearings and suspension parts.

I*m wondering if you have winter tires and they sound loader then your summer tires? Winter tires have a different tread and can have a roaring noise / make noise compared to summer tires.

There are numerous scenarios regarding the noise you are experiencing.
First, if the tires are new this noise would be a characteristic of the tire. In other words, all tires have different tread designs which can cause a tire to make a "harmonic" noise. This does not mean the tire is defective, just simply a characteristic of the tire design.
Second, if the tires are not new and the noise is a new noise this can be caused from the tires wearing indifferently. In other words, the tires may be experiencing abnormal wear due to alignment issues, tire pressure issues, or lack of rotating the tires on a regular basis.
Third, if the tires are not new and this is a new noise, this may be unrelated to the tires all together. We have seen wheel bearings, drive axles, etc., cause this sort of a noise.
I would recommend an AskPatty.com facility to have the tires inspected and have a technician drive the vehicle in order to verify or diagnose the noise. Communitytireaz.com
