I had these on my 2000 F150 before I sold it. I thought they were pretty decent for an all terrain tire. I didn't try much with them other than normal street driving where they were pretty quiet and some light dirt, off road work. They were great in the ice, snow, and rain as well.
I've got nothing bad to say about them. I know some aren't a fan of Firestone products, but I've had no problems and I can get them cheap...my buddy is a tire manager at a story.
