It's not like we are hauling a 5 er with all the weight in the bed. Or am I off my rocker here?
You have a huge sail behind you that, when acted upon by a force (wind) can create force on the tires through the hitch. Soft tires allow the side of the TV to be pushed more easily, resulting in squirm. Basically, if you grabbed the stinger of 2 identical trucks, one with P tires and one with LT, you could induce more side to side movement on the P tires by pushing/pulling back and forth on the hitch. So, it's not just about weight, it's about side to side movement.
