I went from a running 928 to the motor out and on a pallet in 4 hours once. The key is order, and inflating the spare. while you jack up the car and get the old tire off. I also made an adapter to fit a mercedes scissor jack so I could use my makita impact driver to raise and lower the car.
I'm not sure how you change a tire, but it's a 4-5 minute job tops. especially in a questionable area.[/QUOTE}
Now that's a video I'd like to see - a 4-5 minute total tire change from the time you open the hatch to get at the jack and tools, get the car jacked up, get the lug nuts off, swap the wheel, get the new one put on, nuts tightened, and then get everything thrown back into the car, even if you don't put it away properly.
Seriously, post it up, it would be fun and educational for us to see, me at least.

Impressive - you're like your own personal pit-crew.. 
I tend to work slower and more methodically, but usually have the luxury of time.

[QUOTE=Petza914;15699793]The motor was on a bet and to be a smart *** I used his time clock. The bet was dinner on him anywhere in town. My tool bag was in the trunk and he had a hoist. If I failed nothing lost on my part. The mercedes jack trick was for my old SL and when I sold the car I kept the jack. lol I actually used it on a date once and got major points.

4 to 5 min? I'm really impressed. It would take me 4 to 5 minutes just to get the spare out. Then I would have to clean the old tire and rim before I put it back in the car. And so it goes. I change out tires long before they get to the wear marks. My normal for tires is about 4 years. My thoughts are that if I have fresh rubber the chances of a puncher is less. Also I live in denial. Instead of a spare maybe a bottle of Makers Mark or a good small batch gin.

I'm going to say it before someone else does. I can pull an engine in 4 hours but it takes me 10 years to put it back in.

Just a suggestion, put a big plastic leaf bag in with the spare. You can put the flat tire and wheel in the bag, and it won't get dirt grease whatever all over the interior, in the back of the car. I've got a new pair of mechanics gloves in there too, and an old pair of FR overalls from my Halliburton days.

First off, the idea of 'crash protection' is a myth. It comes up every so often and has been debunked more than once.
Also, there has been at least one documented case where the spare looked ok, inflated and held pressure, but started coming apart about a mile or so down the road.
I would be very wary of using mine. However, it's still in the car.
As was noted, having it as an option, regardless of how bad of an option it really is, is something I want.
And with the jack that is in the back, standard lug wrench, and all the other complications that come with changing a tire on the side of the road (done it more than once), I'd expect it to take more than 4 or 5 minutes, start to finish. One thing I do is carry a 'speedbar', the "x" wrench with different sizes on each end. I prefer the way that I can apply torque much more perpendicular to the stud (I've broken a couple studs with a standard angled lug wrench) and once loose, I can spin the lug nuts off much faster. Not as good as an electric impact, but better than the normal lug wrench.

The factory jack and lug wrench are only good for concours. My toolkit contains a 2 foot breaker bar, mercedes scissor jack, a 2x12x12 piece of wood, cordless impact & wheel lock key, as well as the steel lugs as my usual lugs don't fit the spare wheel correctly. Since I did the rear seat delete I have quite a bit more room for tool storage, and also include nitrile gloves and some plastic to wrap the wheel/tire combo.

What's this ?
You added metal cover to your storage area, and what is the wall the hinges are attached to?

Pep Boys, Tire Kingdom & Tire World could not get the old tire off so I gave up. New tire is sitting somewhere in the crawlspace above my garage.

I bought a new tire about 3 years ago after I used my spare and cracks appeared over the entire tire when inflated (but it did hold the air to get me off the Interstate).

Had to use the spare on my 89GT when the brand new Cotinental (damit) picked up a huge puncture on the Motorway just after the tyres shops closed but still miles from anywhere. I needed to catch an early morning ferry about 400 miles south so plopped on the spare. Inflated ok with the original compressor, seemed alright. Not nice to drive on at 70/75 but it served me well all the way to a tyre shop near the ferry terminal next morning. What was great was someone travelling in the opposite direction where I broke down drove past and back about 10 miles to see if he could help. How nice was that!
