Tire shop claims replacing one tire may damage transfer case?

[faz]

Hi everyone,

Picked up a screw in my rear-left tire and it is not repairable. The tires have about a year more life in them (10k or so miles, I think.) I prefer not to change all tires, or more tires than necessary, at this time.

I have always used the local Americas Tire store, and have liked their service and prices and have been using them for the last 10 years. The service adviser there said that they *highly* recommend changing all tires as the in the 4x4, the transfer case could be stressed and damaged if only one tire is changed. I asked them to just leave the spare on and I will think about it.

I don't think changing one tire will cause any problems for transfer case, but then again, I thought I would ask the pros on this site. Have you had any experience with this before?
