My 1981 is carrying the original spare tire, pump and jack. I highly doubt the tire is still functional based on how many other rubber parts I have had to replace in the past 3 years. Should I keep toting it around to preserve the original front/rear weight distribution, or store it elsewhere for fuel economy?

Thanks!

Neither of those scenarios will amount to any measurable or noticeable difference in real life, so personally I leave out the spare for added storage space.

Used mine when got a slash near the sidewall, had to get new tire.
However, major ordeal now as spare gains air stored in cubby and very difficult to remove.

I thought it was an integral part of the crush factor in the rear?

Unless someone produces an official Porsche document proclaiming this, I never bought that theory.

No way Porsche produced a car which relied on a spare tire being in place for crash safety. What if you get a flat, take out the spare, drive down the road at the recommended 50mph....then get rear ended and seriously injured because the safety of the chassis was compromised because the spare was missing.

Honestly the first time I read that I couldn't stop laughing, but I'll proudly eat crow if someone produces proof.

I removed mine last weekend. It's heavy. I had no pump anyway. I do have triple AAA and the tow eye.

A related question: Do you have a tire available at home to replace the flat? Will the car be immobile while you wait to get a new one? If it's a rear tire on the original 16-inch wheel of an S4, for example, it could be a long wait. You don't want to be forced to buy a new set hastily, tires you don't really want.

I save old tires for that situation. I don't think I've ever had to use one, but caution would be required, depending on how old and how worn. In fact, I'll soon have a barely legal but fairly new rear tire stashed away to replace an ancient tire. (Actually, I'll save the other one, too, if anyone at Camp 928 would like it, or need it.)

OP didn't like the answers he got the first time he asked this question?

I'm tempted to merge them, but then anyone who answered in both will look like a schizophrenic.

Howabout swapping it for a newer model Porsche spare wheel with newer tire?

Boxsters and 996+ had a funny little glorified mountain-bike spare tire, like 3.5" wide but the bolt holes are in the right spot...
they even come with a cute little tool kit for the hairdressers to change tires on the side of the road.

I pulled mine a long time ago.

As for the tire being part of the crash testing, I wouldn’t be surprised if it was part of it. BUT for liability reasons it would make sense if the car passed the crash test with an empty spare tire well too. I think the tire helps. My brother had a ’89 BMW 750iL that got read ended at a high speed while sitting at a red light. When I tried to pull the full size spare, it was jammed in there and probably helped act as a cushion. The car got his so hard that the climate control panel flew out of the dash.

Nice thought process!

i cant imagine a space saver spare doing the same thing... its basically just a rim...

can you imagine the force that would be required to crush a steel rim?
