I have been running Hankook DyanPro ATMs for probably around 25k miles or so - paid a little less than $650. 20k of those miles were put in in the Colorado Springs area, with trips to and from Breck almost every weekend during ski season for 3 seasons (both on 24 and I-25/I-70). Only off-roading were groomed trails to go shooting/car camping. I now have 10/32 left on them after the drive from CO back to OH. So fairly decent tread life for an all-terrain tire.
In CO I didn't notice a ton of road noise or any wah-wah-wah sounds

But all the roads in CO are generally loud (I had a GTI with 18's), rough and gritty from people using studded tires all year round and the composition of the roads are different out there. I can tell you I notice the wah-wah sounds back here in OH because the blacktop on the highways are smooth - so I wouldn't worry about it out there. The Springs gets torrential rain storms in the summer and these tires performed great at all speeds. Drove it a lot in the snow on Hoosier pass and down the dreaded down-hill from Eisenhower tunnel to the Silverthrone area in a white out blizzard - did really well. Drove it this morning in the snow in 4wd, flying by everyone without issue. Hope this helps.
