Dan is right, and they do have the big torque wrenches... a different color for each torque. Make sure they use them. I had to insist, as the tire changer was looking for shortcuts, and told me that his gargantuan impact wrench would put them on tight. When I asked him to what torque it stops at, he said when they are tight. I told him we couldn;t do it that way, even though he said that is what they do on all the trucks.
Manager told him to get the torque multipliers out, and use the correct one. He did. I believe he was new to motorhome tire work. Talk to the manager to get it all straight before you let them touch it.
