Will a space saver spare from a 924 work on a 914? (IMG:style_emoticons/default/confused24.gif)

So how do you get a space saver for a 4 lug 914? The 911 space saver is mounted on a special wheel. Is there a way to mount a 15" space saver tire on a stock 4 lug wheel?

I have A/C and would like some of my front trunk back. (IMG:style_emoticons/default/fighting19.gif)

I have a customer who took and installed a very short 50 series tire on a stock rim and stood it up against the firewall that seperates the fuel tank from the front trunk. It works well and clears the hood.

I have put space saver from Saab to stock 4,5x15 Porsche steel wheel. No problems. But, it is not like the flat one you have in the pic. It is small and narrow. I think the sice is 115/65/15. Sorry I dont have a pic abou it.

I have seen space saver tires mounted to Fuchs wheels, so that is an indication that they can be mounted to other wheels than they came with. Doubt your average tire shop would be able to do this. You would probably want to get an old 4.5" wide steel wheel to put it on.

Any chance an Audi 4000 spare would fit? At least they are 4 lug. Oops, guess it would be a little short.

I did this...

I found a space saver in a junk yard from a 280/300 Z car that was a 14incher. The reason I chose this one was that it was an inflatable, like the factory used and I got a compresion bottle from the same junk yard.

Yes, take it to a tire shop... they can dismount it and remount it on your wheel (I used a 14inch fuchs to keep the entire unit short as I too, stood it up against the front tank inside the trunk)

[mounting to the trunk is another story]

When the inflatable tire is blown up it has a tall sidewall (probably 70 - 80 series) and matched up very well with overall height to a street tire.

A temporary spare is fairly small, I have a 125-15 on my bug I checked it on the 914 it will stand up like Brad said. Mount it on a 4.5X15" bug rim. I got mine at a scrap yard for $5 new and it cost me 5 to get it mounted.
Mine was out of a GM grand prix I think.

This is really good stuff... I dont drive cars with spares so I'm not "hip" on what to do.

I'll make sure we keep this thread around and make a tech page out of it.

Can anybody get us some pics of their spare setup ??

Hey B,

You still need a spare for the silver /4?

I have a steel 911/944 spacesaver that I am no longer going to use.

I been watching that spare tire for a while and thinking the same thing, partwerks is selling it. If you buy it let us know if it mounts to a 914 wheel. I sent them an email asking that question a while ago and never got a reply from them

I don't think you can take it off the wheel. Looks like a special wheel & valve stem similar to the 911 set-up. (IMG:style_emoticons/default/confused24.gif)

Back when my 914 was a street car I bought a 135/15" and put it on a 4.5" rim from a VW shop. Works like a charm-sits about 2" lower in the front trunk and weighs about 1/3 as much as the stock spare. I still have it.

Sorry no digi-cam.

My temporary spare is a T125/70D-15 it measures 21-3/4" X 4-1/2". Like I said I paid $5 at a local scrap yard for it, it's brand new, still has the little nubbie's on it. No special mounting, I've got it on a VW bug rim.

You would need to keep a set of the steel wheel bolts with it if you have alloys

Here is mine - it is a normal 15" space saver that I had a tire shop pull and mount on a 4.5" 356/early 912 steel wheel. It cost 40.00 installed.

I like your install Scott. Is there any concern that you won't get the same crash protection with the spare mounted vertical vs horizontal?

Hi Jon -
My car is pretty low and has fiberglass bumpers - I figure other than a wall, everything will be most likely coming up and over the top and through the glass!

In all seriousness, I figure that without the tire lying down it will be easier for the nose to crumple, therefore absorbing energy. The tire laid flat is pretty rigid, so I would think that it would be more likely to deform the front firewall/gas tank area, actually causing more damage to the pedal box area.

I hope none of us ever have to find out if this theory is correct or not.... (IMG:style_emoticons/default/ohmy.gif)

Are the 911 space savers spares only supposed to be used on the front or only used for a limited amount of mileage?

I ask because I just saw a Motorweek segment on space saver spares and one point they made was that often a space saver because of it's different height will constantly engage the differential like you are going around a turn. They said this could easily wear out the diff in short amount of miles. They recommended following all of the manufacturer instructions, like no more than 50mph and no more than 25 miles driven on it.

I was wondering if this would apply to a 914 differential.

hmmm, i thought the spare tire laying flat was supposed to be a more "RIGID Crushzone" (is that an oxymoron?) the car is too soft and will crumple into the cockpit.
the "rigid" rim and tire will eat up alot of the damage before going into the cockpit. this is my understanding...ill ask my physics book...or teacher <_<
