Apparently Chrysler MFG., made a great screw-up when they decided to put a temporary "donut" tire/wheel rim as the spare in their Grand Cherokee. Everyone who has a 4X4 knows you cannot possibly drive a four wheel drive vehicle with off size tires! Everyone, that is accept Chrysler. The '93 came with the donut on a "full-time four wheel drive vehicle",was it the manufacturers intention to do this? If you drove it this way, surely you'd have either wasted the transfer case, the transmission and the motor too, or possibly all three. If you simply put the donut on and decided to stay "at the side of the road", whats the point in that? I now own a '99 Grand Cherokee and see that they now provide a full size spare. The point is, not everyone knows that you can't drive a 4X4 with a donut on it. So, there are probably some people out there that totally screwed their drive-train up, by doing so.

I asked my housemate once, if she ran into that problem? would she still drive the car? Her answer was a definite yes!
