Yeah wasn't saying for the OP to purchase these, just saying they are not that noisy.
First off I thought this was a thread for "recomend me a quiet tire" not a "recomend me some tires I don't want" thread.
Secondly, I guess if you compare them against other aggressive tires, they aren't as loud as more aggresive tires, your right. My Yokohama MT's I used to have were much, much louder. I'm sure my new bfg mt's will be louder as well.
A strictly highway designed tire will be almost silent though. As in a ton quieter than any at.
