So far I really like them! I have only had them since December but I have made a few trips to spokane with them and portland also. I had BFG All Terrains before and these seem to be about the same noise wise, handle very well and seem to drive smoother on and off road. I should also mention that I have the C load range on my rig. I don't have them studded, but like you said they are pinned for them and would be absolute monsters on winter roads if they were. I had mine fully siped and plan on running these all year round. I live down in Clarkston, Wa so we don't get as much snow as Spokane, but we get some. I have made a few trips to the mountains with them also and they performed really well in deep snow and the hard packed roads getting there. Overall I am really happy with them thus far and would definitely recomend them. Let me know if your looking for anymore/other feedback on them and I will try to help out

How do you like the discoverer ST's? I'm about to move to Spokane, WA and need to replace my worn out tires and i'm looking for advice. Do you use these tires year round or only during the winter? I see they are studdable to do you just stud them during the winter and then remove them for summer? Thanks! I'm more concerned for on-road reviews first since you got to get to work thru the week and play on the weekends.
