[TR] Space-saver or full-size spare?

Hi David,
As the designer of the Boyd tank (http://tr6.danielsonfamily.org/AluminumTank.htm, I can say the design was done with the use of a Space Saver Spare (SSS) in mind. Actually I’ve had a SSS in my car since ’08 (http://tr6.danielsonfamily.org/SpaceSaverSpare.htm ) and didn’t give the full sized spare a second thought in the tank design. A SSS gives you a nice flat trunk, extra storage space and saves over 17 pounds of dead weight versus a full size spare.

Subject: [TR] Space-saver or full-size spare?

I had an aluminum fuel tank from Boyd Welding installed in my 74 TR6. I knew that it was larger than the standard tank. So when I picked up my car, I wasn’t surprised to hear that my spare tire was a tight fit. Only today I found out that the spare fit only because it was deflated! Fortunately I made the discovery in my driveway.
So I need a spare tire.
What is the thinking of list members for getting a ‘space saver’ tire instead of one that is full size?
I wouldn’t plan to drive far or quickly on a space-saver, and having flat space in the boot would be nice. On the other hand I’m not sure if my tailpipe would drag or whether a short drive on the space-saver would cause other problems.
The (deflated) spare is a P205/65 R15. If I were to replace it with a full size tire, I plan to look at something as narrow as a 175/65R15. Being 30mm more narrow might even allow me to inflate my spare!
Please let me know your thoughts.
Thanks so much.
