I hear the TSL "being bad on the road" thing all the time and I can't say its a bad tire in my experience.
Given that I am not commuting in my M715 they will probably last forever nd dry rot off before they wear out, and I keep the pressure checked regularly.
They are a bit noisy, but in the 715 that isn't a worry either. In fact I can't hear them once the transfer case comes in at about 35-40 MPH.
They are supporting a 6000 lb truck, so I wouldn't expect many tires to live terribly long except a tire for a road tractor, but then the off-road thing is out of the question.
