Suprising just doing a steady 60mph on the highway I cant even tell I have offroad tires. They are just as quiet as my moms car. Windows open and all and there as quiet as any car. They dont hold stones in em. The tread pattern is designed to prevent them from getting stuck. From my 2 years with em I find them to be the best all purpose tire wether its in snow, 4ft of mud, rocks, highway. They do it and and are just fantastic IMO. I dont know if I should say this but, one day when I was greasing the front and just checking over everything, both my front tires had 2 nails in em, the rear had 1 nail in it. Never went flat either. Cleaned em up, plugged em, and hit the park. They definatly got my vote.
