Here's a new one. (tires)

So last week I went to my favorite tire store in Bozeman, MT to get some new shoes for the rig. The tires I have are 60K miles or 36 months. I had 45K on so a warranty was do. They measured the tires and told me that the inside was worn about 3/64's more than the outside indicating that the rig was out of alignment. It was aligned after the last set was put on. Now here is the new one, the store owners son, not young, told me I should have the front end aligned with the the TC on and when driving without it it should be re-aligned as the camber will be off under both circumstances.
I normally put on 8K miles a year with the TC on and less with it off.

The question is have any of you ever heard of the necessity to have your truck re-aligned whether the TC is on or off.

Buy the way, they haggled which I knew they would so I ended up paying $500.00 for an $800.00 set of tires.
