Of course when these trucks, even into the 70s, were new, they actually were used on farms. They had bias ply tires and the farmer wasn't driving on the highway at 60 or 70 mph. They didn't even have many highways in the 50s anyway so ride quality or wandering or noise or whatever was not a consideration.

The farmer drove on rural roads into town at 30-40 mph.
