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

Looks like a good match. I must say that over the years I have been very fortunate and have seldom needed the spare tire that I had (or usually didn’t have). Most flats I have discovered were in the morning when the car or truck was sitting in the driveway.


I think the only thing to remember is that once you have a flat tire, where will you put it if only a space saver will fit in the spare tire compartment. If the car is fully loaded up - truck, rack, and behind-the-seats - as on a long distance trip, the passenger may object to keeping it in his or her lap until you can get it repaired and back on the car. Of course, if the full size tire is fully deflated, maybe this is not an issue as it might fit where intended. 


Bob – I always amazed at the amount of material that you have published on your website! I learn something new every time I visit it.

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.

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.
