Spare Tire option

[MikeD1]

I know the rears on the PP are wider but can you, at least temporarily, swap a rear wheel to the front and put the spare on the back? I had to do this on my last car. It worked fine but the wheels weren't staggered.

That sounds dangerous to me (and a lot of work jacking & moving tires around). Now you have mixed wheel/tire sizes both the front & rear - eeek !

not something I would want to do. Particularly on the side of a road, and without proper gear, floor jack, wheel chocks, etc.

Im not sure. Might have read either they won't fit or it destroys the gearing within 5 mikes. But ill lean toward not sure and will default to someone with more experience.

I read you aren't supposed to mix tire sizes with the LSD / Torsen

you could get around that by swapping the stock diff with an Open Diff

then you can run the 18" donut

Better to look cool than be cool

As an aside, I don't think the donut is supposed to be run more than 50mph for 50 miles. So its not all that exciting.

You could always just trade the Mustang for an F150. Those still come with full sized spares

I believe the PP rear wheels are too wide to fit in the front and will rub. I could be wrong though.

I'm pretty sure the torsen on these cars is capable of having a donut on one end and a regular tire on the other. At least that's what I remember reading about with this type of torsen.

I plan on on getting another GTPP front wheel for a full size spare and securing it in the trunk. It should fit deflated. I just need to figure out how to keep it in place.

Deflated? Meaning with slightly less pressure or with no air?

From our conversation thus far I don't think anyone has said difinitively what Ford has put out or what the 100% safe route is here with swapping out wheels.

So I'm curious how easy these wheels/tires are to get replaced in a pinch? Are they the kind you can stop into any wal-mart and get one or are do they need to match the others on the car (tread-wise) and you have to order it off tire-rack and wait a week?

The only place I can see this turning into a royal pain in the ass is a side-wall puncture on a road trip (or away from home). Otherwise, if these differentials aren't real finicky, just have a 19.5" and 19" (I think that's the sizes) mounted on steelies at home in the garage so all you need to do around your home area is have the car towed to your house and do whatever swap is needed. Shouldn't cost more than $200 to keep a cheap set of spares on hand in the garage. Not sure they would fit in the trunk together and with a suitcase definitely not. So I doubt carrying them on trips would be possible.

Personally, I'm used to 15"-17" wheels so I'm not sure what all is available and required in these sizes.

I've been driving for well over 30 years and never had this "true blow out" that you speak of. Every flat I've ever had always was a slow leak. Some were not repairable, but they still didn't leave me stranded.

In the past 5 years I have had 4 flats. Two were slow enough that the compressor instead of a spare would have worked. The other two it wouldn't, one the tire started going down on the highway and by the time I could get to the shoulder the tire had broken loose from the bead on the rim and the other a 1" long piece of steel punctured the tire. Luckily I had a spare instead of a compressor for those two.

In my 40 years of driving I would say all the flats I have had the 50/50 ratio has been pretty close for flats that could have been handled with the compressor.

Back in the 70's I bought a set of radial tires (my first set ever) and over the course of a couple of months I had 3 blowouts. Turns out there was a defect in the sidewall construction resulting in the sidewalk rupturing. The tire store gave me 4 different brand tires.

I've read the exact opposite. 5 miles on two different size tires and it will be destroyed. I think what I read was an excerpt from the owners manual, but I'm not positive.

I bought this one for $226.00 delivered http://www.tascaparts.com/oe-ford/fr3z1k007c

So with the talk of the Mustangs that are "PP" equipped, would the above spare kit fit or not fit? I'm seeing that same exact kit listed on some other sites where fitment is showing its good for PP Mustangs (EB or GT)....

Any real confirmation to the above?

As far as running a full size spare - I have yet to see anyone selling single PP rims w/tires for $200, unless I'm just missing them during my searches - seems those wheels are commanding a premium right now due to how new our vehicles are and supply vs demand.

I also have AAA - and as others have said, used them before - but response time is all dependent on:

1) vehicle location vs. X-Garage that was assigned the AAA call
2) time of day
3) their call volume

Some of us have waited literally an hour or more just for AAA to show up, when if having a spare - the stranded driver could have swapped it and been back on the road in 30 mins. Here's another factor thrown into the equation to think about - what if the failure occurs at night after shop hours - then the stranded driver still needs to make a decision:

1) do you have AAA tow it to your home (if within distance)
2) do you have AAA tow it to an unknown shop in an unknown area, leave it there overnight then you still need a way to get to your destination (unless you're gonna sleep with the car)

Plus who knows where to tell the AAA driver to go for a shop that carries the exact X-brand tire for an exact replacement on PP vehicles (and if the tire would actually be in stock or not)?

Seems having a spare to get moving again is better than AAA with the "what ifs"....

Good discussion!

After having a tire blowout, I deeply regret not getting that option.

Here is what I was looking at:

Is the T-2R not the same as the T-2 (Type B)? The way I reading seemed like the R is just a more stout version.

Great points! This is why I'd really like to find a suitable spare tire option that wont ruin/hurt the car at all.

Ill also share that ive waited 3 plus hours for a AAA tow...

I bought the spare.

Reasons:

1) If you have nice rims, have a puncture on the highway, you will no longer have nice rims if you have to drive miles to a service station.

2) I rather have my insurance with me, I'm not to lazy to change a tire, I understand some people can't turn a wrench so they call AAA. Not me.

3) I can easily remove it if I'm at the track for weight savings. It takes 2 minutes to remove.

No spare...no cell...no AAA

I went for the spare tire option. Two years ago I was driving my 2010 GT with no spare on a county road in Northern Minnesota. I must have hit road debris...the tire deflated in less than a minute. Reached for my cell...no signal.
Walked a mile to nearest farm house...no one home. Finally a Harley pulled up and tried his cell. He got a weak signal on 911. County Sheriff sent out a AAA flatbed. It was 8 hours before I got on the road again.
