Manual or not, take a 235/80 or 235/85 tire, allign it with the wheel properly, see how many of those don't take a significant amount of weight. Especially when they are mounting a $75 tire.
My opinion is that they don't balance them because you can't feel what's going on back there from the cab. If we could feel it, it'd be a different story. I replaced my factory tires and had the new ones balanced right out of the gate. Less vibration means less to go wrong back there on the inside... At least that's my unproven theory based on absolutely nothing...
