Space Saver Spare Tire or just a Spare tire
#1
Do all 71-73 have space saver tires? Or is it only with fold down rear seats? If not does that mean others have a regular sized spare tire? Just asking as I'm confused cause I have a 71 with no fold down seat with a regular sized spare.

No. All 71-3 Mustangs did not come with the F78-14 space saver spare.

Certain options made the space saver tire necessary:

1. Rear Sport Deck rear seat, aka "fold down"

2. FOR 71 and 72 only: F60X15 B/WL tires (Black Sidewall Tires with Raised White Letters).
with either 15" steel wheels, trim rings and caps OR

3. FOR 71 and 72 only: Magnum 500 wheels (only offered as 15")

For 1973 I am not sure if the spacesaver was used for anything other than cars equipped with the fold down back seat?
My reasoning - Magnums not stock (factory equipped) for 1973.

Hmm, interesting.
If not equipped with the "sport-deck" rear seat option,why would having any of 15" wheel options require a space-saver?
My 72 Mach 1 without the sport-deck, but with standard 14" wheel/tires came with full size spare.
My 71 with sport-deck and Magnums did come with a space saver. I always assumed the singular criteria was wether it had a sport-deck or not, considering that a full size spare will not fit in a sport-deck trunk. I can't see why any of the wheel options would make any difference.

Not sure why. But it (15" tires/wheels requiring space saver) is what Ford lists as being the way it was when they were sold.
For why, I could guess that the engineers thought it might be too much space taken up by the 15" full sized spare? Hence calling the collapsible one a 'space saver'. (BTW Not trying to sound like a smart a__!) Maybe they thought the customers would have trouble trying to 'wrangle' a full size 15" spare??? Or they needed the extra space to sell all that trunk space!! Big Grin All my Ford literature lists the 15" tires/wheels forcing the space saver to be equipped.

Your 72 Mach 1 without fold down seat, with the standard 14" wheel/tires helps confirm the info I posted. It would have not come with a space saver. It probably came with a full size E78-14 or F78-14 as the factory spare.

I thought it was an option for convertible cars as I have found it in a couple of convertibles.

Never knew about the 15 inch wheel deal but the verts with space savers had factory 15 " magnums.

Can a new space saver tire set-up be had these days? I'm curious, because I'm planning on sucking up some under rear package tray space with a box & subs, and a full-size-ish spare would pretty much kill about 1/3 of what's left of the little bit of trunk space we have.

Initially, I'll probably just use one of the tires that came with mine (14" rims and 185/70 series tires), but then I'll be needing to find something more permanent (either a full-on space-saver rim/tire - like from a Crown Vic, or a skinny/tall matching Cragar S/S rim/tire). I'll probably go with the Cragar option though, just to be cool. Cool

I went with the spare from a Crown Vic. Cheap at the junkyard but still a tight fit with the fold down seat.

Me too. Space savers are way cool and worth the money if you show your car, but I would not actually use a 35+ year old version.

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!
