The fuel saving from doing this will be miniscule. Better off adjusting your driving style or running with less fuel in the tank, making your Mrs walk etc.
I remember one of the car programs did this a while back and found no performance/economy gains until the whole car had been stripped down to just the drivers seat or something like that.
I deffo wouldn't run without a spare in any case, I would rather change it myself in 10 mins than wait 30 mins or whatever for the AA and then have to be towed to a tyre shop anyway - would be more embarrassing having to tell the AA man I didn't have a spare due to trying to save weight

Making the missus walk sounds like something I could get the hang of!
I just thought I would ask the question really.
I too would much rather have the spare in there to be honest I mean, can you imagine the converstion you will have when you get a flat on a long journey going on holiday and your missus (if shes not walking) turns around and asks why there is no spare and you have a 2 year old in the back starting to get irritable!
So the spare stays......hehehe.
