Well, guys, if Yokohama still produces tires model AVS dB you may guess why they named them that way. I bought them, many years ago, just for that reason. They were supposed to be quiet and quiet they were. It was a drastic change in silence from whatever my stock tires were at that time. Having said that, they were quiet for about, let's say, 5000 miles and then they were the loudest thing you could have ever imagined. They somehow warped and ended up having ridges, valleys, hills, etc. on them. I was in love for a few thousand miles and afterwards had to admit that first passion does not always last so they went away. It turned out I was not the only one who noticed this increased noise so, maybe, they improved it afterwards.
