Tires on Tow Vehicle

Hi. I have not found a thread on this topic, so....

I tow with a 2004 Volvo XC90, and need new tires. I have been riunning Nokian tires the past 5 or 6 years and been very happy. I used the WR2 SUV tire, and went with the WR3 when Nokian moved to the WR3, and I have been happy.

However, I am now thinking of the Nokian Rotiiva AT, which tire gives me more offroad capability while not sacrificing onroad or winter/snow capabilities.

Am interested in what folks think about a tire that gives some capability offroad. Although we only take TD a bit offroad (on dirt/gravel roads that are in good shape and won't shake the TD to pieces and fill it with dust), we do often go down more formidable dirt roads with the Tow Vehicle, so I want some enhanced capability from my tires.
