Different size spare

I was under my truck doing a couple things and happened to notice the size of my spare tire. I have the factory 20s. 275/65/20. My spare tire is 275/70/18. Am I correct that i can not use this tire as a spare if something happened? Dont all tire sizes have to be the same diameter on a 4 wheel drive vehicle? I bought the truck new from dealer. Did they just add the 20s and forget about the spare? Can I take it back and have it replaced if needed? I bought it new in 2011.

No I think you are fine. Someone else will confirm though.

I've read here that you just make sure you put the spare up front to keep the rear 2 wheels/tires matched. So if a back tire goes out you need to move one of your front wheels to the back and put the spare up front.

I'm sure someone who understands this will explain reasoning, but that's the process from what I understand.

This is correct if you have a limited slip rear end because running 2 different size tires will wear out the clutches in the limited slip real fast.

If you have an open diff. then you can run different size tires without hurting it.

Those tires are 1" different in diameter. You would have to put the spare up front like everyone has already stated.
