I can speak to running a 275-17 Nitto DR in front. The biggest performance issue I have with them on the front is the sidewall stiffness. The soft sidewall has a delayed response to steering inputs compared to a street radial. It needs higher pressure to help stabilize it and then it performs OK. I have to think a 15" DR would exhibit this characteristic to a much greater degree... I suppose you'd have to try them to know if the feel is acceptable for your type of driving.
