I have a dirt driveway and travel the numerous dirt roads in town ....because, well, they're there! But I don't air down and ride them aggressively. If that's what you want to do, maybe 705's would be a good choice, especially if you're younger and stronger than this retired mason....:beatnik:
Tire selection is another trade-off. I wear plugs on longer than 10 minute errands too, but once I heard what sounded like a worn wheel bearing noise coming from my A 3's, I would always be listening for it.
In my previous post, my buddies' son went on the Trans-lab trip too, on his F650GS fitted with K-60's. He said he couldn't wait to get home and swap them out for something quieter (he chose A-3's). In fairness to K-60's, the narrower width his GS takes don't have the solid center strip that our 150 rears have, so they would be noisier on his bike than a Vstrom.
Everyone's noise tolerance is different. I do suspect that most of us with hybrid tires spend more like 95% of our miles on pavement. Our bikes are certainly designed more for on road than off.
