Old thread is old, but I would still like to opine:
I daily drive my overlander,. However, fortunately, my daily commute is an urban 11 miles round trip. and the speed limit never exceeds 40mph.
Considering this, I wanted to go with a MT tire to offer the most capability off-road, knowing I would be making a sacrifice on-road. After shopping around, the best tire in my opinion that was available in the size I wanted was the Cooper Discoverer STT Pro.
I had never owned a mud-terrain tire before, so I wasn't totally sure what I was getting into, but the reviews were reassuring. After approximately 5 months, I can say I am very happy with them. More noisy than the Toyo OpenCountry ATs I previously had? Definitely. But, I don't find it unbearable. Definitely still capable of having a conversation in the cab at highway speeds. Most importantly, I haven't lost any confidence in all on-road conditions, meanwhile, they have been really good in all the off-road situations I've put them through so far.
Two nitpicks:
Their sidewalls are mega-stiff - there's very little pooch when airing down.
They pick up and retain stones like mad. I'm tap-dancing down the road almost every day.
