I was tinkering with stuff yesterday and remembered to go under the trunk and check the PSI on my space-saver tire and it was a 32.5 when it should be a 60 PSI. I filled it up to 61.5 and put it back in the trunk.

I have considered using a spare wheel I have and putting a tire on it and keeping it in the trunk but don't want that extra weight back there if I don't need it.

Yes, an often overlooked maintenance item. Only takes a few min to check and fill up.
I keep a small air compressor in my trunk, good thing cause when I needed to use my spare, it was down to 20psi.

My car didn't come with a spare. When I bought it had an air compressor and can of GM Fix-a-Flat. FYI, new from dealer in July 09.

Only the V6 came with an actual spare tire. GT and GXP just got the Fix a flat/air compressor.
I bought a full size wheel and tire, and put it in place of the Foam and kit. Fits perfect. Even have room inside the wheel to store some things!
