Now after almost 1000 miles...tires are relatively quiet, not intrusive by any means. Smooth. Stable. And no problem taking the curvy mountain roads through the Smoky Mountains Nat'l Park or the unimproved mountain roads also found there (i.e, Parsons Branch Road to HWY 129- the Tail of the Dragon and Rich Mountain Road. Both are ~8 miles of dirt, gravel, rock, ruts, water, and so on...great fun). Also, very comfortable cruising at 80+ on the highway.
I'm very, very pleased with this tire. No serious off-roading yet unfortunately but soon I hope.
