I'm on my fourth set of Toyo AT's (Land Cruisers & Ram 1500). I'm mainly on the road but spend some time in dirt, mud, hills, sand, etc. Never one problem. Quiet on the pavement and a great life span - I love these tires. I had a set of KO2's for a spell and they do balance like crap as Tex68w pointed out - I replaced them with STT Pro's. Problem solved. I still would choose the Toyo AT's over everything for mixed use.
