torque specs for wheels

On his old truck that he did that he had to redo the brakes 2 times as they Rotors were warped.
Wonder WHY? I told him Cheap Thin and "Over Tight" lug nuts.
He says but Tire places use them! I said but they also use Torque Sticks.
He is doing it on the new truck now too. Bet he complains to the dealer
