It's designed to be a very temporary solution. As long as you make sure to put the spare on one of the rear tire locations you should be fine. If one of the front tires is the flat, you'll want to rotate one of the good rear tires up front then put the spare on the rear.

Ugh... Seriously? Its not bad enough that we're talking about the hassles of changing a flat (often on the side of the road, in a parking lot, etc), but we should also move a tire from the back to the front?

Thanks for the tip - I had no idea, and obviously missed that in the Owners Manual.

Not sure if that's in the owners manual or not and only really pertains to those of us driving on the larger wheels. The spare is 17" so if you have the 18 or 20" wheel option, the different size in the tires could cause some damage if you run the different sized wheels on the front. We don't have a LSD so there may be binding due to the different rotation speeds of the wheels if the different sizes are ran on the powered axle. The different sizes don't matter in the rear due to them just being free rolling and not really connected to each other.

Are you sure that the outside diameter of the spare when inflated is that much different than the standard tires? Whether the spare is on a 17", 18", or 20" wheel doesn't mean much by itself as the tire size can be adjusted to maintain the same outside diameter (as is done with the 17", 18", and 20" wheels on the Pacifica).

I haven't inflated the spare to measure what the outside diameter of the inflated tire is compared to my mounted ones. Pretty sure it will be smaller though as it's probably similar to a compact spare.

I've never heard of having to rotate tires around when using a temporary spare. Yes, the outside diameter will likely be different, but it's only meant for very temporary use. If Chrysler expected you to only use the spare on the rear, I have no doubt that would be in the manual and likely printed on a warning sticker on the spare itself, no?

You can definitely use it wherever it's needed and the most important fact is to only use it temporarily at the prescribed speed. My point is more to the fact that when you run tires of differing diameters as drive wheels, the drive train may experience excessive stress since they will turn at different speeds.
