I pumped up the Inflate-O-Matic spare today..PIC included!

I just had to try it. It worked just fine. I used the ivory factory pump, too. It sort-of took forever, and I had to let the pump take a rest to cool, but I got it all pumped up! It says max press 32, and max load 1105 lbs, so as we have discussed in earlier threads, it probably should only be used on the front, and if a flat in the back move a good front tire to the rear and use the spare on the front.

But I think it looked pretty good for a 25 plus year old tire!

I let the air out with a small phillips screw driver, (I still don't know what that extra thingie is for that is next to the valve stem) The tire shrunk back down to it's original storage size, hopefully for another 25 years.

Next project is to see if I can use an extra Subaru scissor jack instead of the danger zone factory one...

That's a good idea - test inflate it before you really need it. I should do that to mine also.

Good Morning all, Just out of curiosity-do you guys think this is an incredible result for a 25 year old emergency tire? Everytime I work under the front carpet I glance at mine and wonder if at this point it's dead weight...

Mine looked ok as well when I did that. 27 years old.
I guess it is down to the place where it is stored no sun gets to it nor does it get very hot.

One of the first things I did when I got my car was go buy a pump (the original was missing, but I found a cheapie replacement at Wally world) and check my tire. It worked great. Then I realized that the other key item along with the pump that was missing was a jack! LOL!

Found one in the classifieds but really, really glad I didn't need it when I didn't have it.

Of course, now that I'm ready for a flat, I'll never get one.

I inflated mine to 30 pounds outside in the cold, then I put it into the heated garage where my '74/75 911 is stored. After a week it gained 1.5 pounds of pressure! Due to the warmer temperature in the garage, I guess. Anyway, I also examined the tire with a magnifying glass and could not discover any cracking whatsoever. This seems OK to me. The jack was in the car when I bought it, but no lug wrench or compressor. I got those things, so I feel fine.

I have had to use my inflatable spare twice. Both times for a rear flat. I went ahead and used the spare on the rear with no ill effects. Of course, I drove under 50 mph and only went about 25 miles. One thing I have learned is that the low profile tires will be ruined even if you only go a very short distance after a flat. The sidewalls develop serious bubbles (broken cords?) requiring the tire be replaced. I use the Falken tires on my SC and that is the only problem that I have experienced with them. Out of a personal preference, I replaced the original jack with a screw scissors jack for a more stable lift.
