I have the original space saving tire in the trunk, witht the bright red wheel. It probably has never been blown up and is now about 18 years old.



Should I blow it up and then let out all the air once in awhile?



Is the tire even safe to drive on as we all know the rubber dries out after about 5-7 years.



How fast could one go using that tire in case of a flat tire?

My mechanic has inflated them and has never been able to refold them.



My plan is to just call someone to pick me up and go get my flatbed trailer, but everyone else seems to think a cell phone with AAA works as well.

Many owners have removed it completely to save weigh and increase options for things as mounting a stereo and amp.



I would not inflate it.

I would not drive faster than 20 mph on that tire. Sure the rubber will be dry and far from ideal condition, but in a pinch when you don't have phone reception to call AAA , it'll probably still do its job for a few miles. I'd inflate it to see if it holds air just for safe measure. That said, even when brand new I would be hesitant to go more than 35 mph on that thing, no matter what Porsche indicated might be a safe speed ( 50 mph IIRC ? ). I removed my spare tire a long time ago and never needed it for the last ten years. Of course I have not had a flat for the last ten years, lol.

Again, everything I have seen, read and everyone I have asked, says don't inflate it unless you need to use it, then you won't get it back down again and you will have to buy a new one. I believe they were a one off...

Can you still buy them?

Not sure - I would have to call sunset to see. I was told they were a one use thing. Use it and replace. I am sure Flash would know off the top of his head.

<acronym title='previous owner'>PO</acronym> of the white car used the spare and it does not deflate enough to fit back into place, so I have it sitting in my garage. For a minute I contemplated taking it to a tire shop to see if they can somehow suck out the remaining air...reverse compressor? Vacuum? Quickly decided to save the weight and leave it in my garage.

I carry the spare from a Boxster when I take the car out of town or if I'm going to be in the middle of nowhere.It works in a pinch as I used it once late at night when I had to go get my wife, who had busted a wheel.

Yea, I have been told even with a vacuum, you can't get enough air out of it - there is a way it is folded that cannot easily be replicated once it has been used.

I've inflated and deflated mine three times it collapsed back to its original size with no problems.

My compressor is long gone. Could pick up a cheap one at Harbour Freight but am wondering, will a can of fix a flat inflate that thing?

Chris did you use the compressor which came with the car ? I get the impression it would take a ridiculously long time to inflate that spare tire with the OE cigarette lighter powered compressor. One of our former NorCal 968ers said it takes twice or there times as long to inflate that small tire as it does the regular tire , inversely proportional to the respective sizes...that would also lead me to think a can of inflate-a-flat would not do the job . Maybe a few of them...



Also, those who modded the suspension to lower the ride height won't be able to use the OE jack either; the lower position somehow changes the angle and pushes the jack against and into the rocker panel. So if your car is lowered and you intend to use the spare tire, get yourself one of the mini-pneumatic jacks from any auto parts store and carry that one instead of the stock one.

another post deflation question:



did you bolt the tire back into the spare compartment, or just leave it loose?

DS- I used the compressor that came with the car. It doesn't take too long to inflate. It is a low output compressor because it only runs on 12 volts. The only problem I had with using it is that if you run it too long as I did the other day when adjusting the tire pressures on a lll 4 tires it may cause the fuse to blow.



Flash - Yes the tire pits properly in the well and is bolted in place.

one of these, they have a 2 ton lift power model or 5 tons, or 8 tons ( in case you're giving Gov. Chris Christie a ride at the time..) and they're very compact, but not lightweight

First thing that happened when I bought my Cab was getting a flat tire. I used the factory air compressor and factory donut spare(thankfully, they were both there!) to get me to the next town/exit and was able to put everything back in its proper place. When I drug the Tip COupe out of the mud, it had the donut on the passenger rear. It was horribly dry rotted with big gaps all along the sidewall, but it was holding air! These things seem to be super durable, but as they get older, I'd have to wonder. I didn't deflate it as I figured it was no good, so it went to the great donut tire retirement home in the sky. I see them pop up on eBay every now and again and they go for more than you'd expect.

Pretty sure most auto stores ( the larger ones " chain " Autozone, Pep Boys, O'Reilly , eyc ) have them , and I suppose Sears would carry these also. I don't remember how much I paid for mine but thinking it was less than $ 30 for the 2 ton one. I'd check eBay also , and see if anyone offers free shipping .. I think they're called hydraulic jacks , not pneumatic as I labeled them, lol..
