The Vredstein Quatrac 5 is a good tire but has a poor wear rating, I seriously considered them but that was a deal killer.
Not to argue however, Tire Rack's test doesn't particularly consider the Quatrac 5 a quiet tire. But, the Customer Rating/Review may show it to be quiet, IDK!
I believe TR even mentioned that the Quatrac 5 was one of the louder tires in its particular test. I guess this doesn't mean it's a loud tire, just more noticable I suppose?
TR site is down right now so I can't double check yet.
