TRX seems to be an answer to the question that more than 5 people were asking...lucky you!
I do agree that many do not actually go into compromising situations. My 2wd will be getting slightly more aggressive tires that are better in the rain and will do better in a muddy parking lot/soggy field/sandy beach. Those situations represent a small fraction of usage for me, and obviously represent a larger fraction for others.
The Goodyear Touring tires are NOT the best choice. It isnt that great in rain and accelerating through a corner (i.e. from an intersection turning right) with the most modest of feet can illicit a screech from the inside right tire...with 3.21 gears, no less! They dont even have rim protection! Obviously, an engineer/the engineering team didnt make this tire their first choice, but as a compromise of many factors, including incentives from Goodyear, production capacity, fuel economy, etc.
To the OP's question, I've never towed but I've hauled roughly 800lbs of bricks and it didnt squirm like my 07 Ford FX4 Screw with 18's and plenty of sidewall. Though I had the original BF Goodrich Rugged Trails on them...not an LT.
