However, they are just a tad louder than OEM. It doesn't bother me and am used to it now. When I first put them on, it took a while before I even noticed it and then once I realized it was the tires I immediately stopped thinking/worrying about it.
I just got my ears calibrated and will tell you these tires are exactly 2db's louder than stock.
For the performance and cost I can tell you that I am glad I bought them.
