I've had the ST Maxx on my Silverado for 40,000 miles and they aren't loud at all. The only time that I notice a slight hum is when I turn the radio off on the freeway. Even then it's not bad, I could run on the road all day long like that and it isn't loud enough to be annoying. I'll be replacing the BFG's on my FJC with a set of these.
How are the ST Maxx on the road? I have the STT and they are LOUD. Looking for something a little quieter for my next tires....
