fix a flat is wonderful... unless the flat occurs while driving. I say that because if you are driving, it is highly likely that your tire will shred itself and thus your fix a flat won't do anything.How much does a spare add to the cost? Plus the mounting hdw? I believe I would prefer a can of Fix-a-flat and drive to the next tire repair facility, which I would need anyway. Let's don't overthink this for the base model.
Now, a spare tire would cost not too much but there just isn't anywhere good to keep one... maybe your garage back home where you'd have to call for help. But, I digress.
Hey, in the interest of well, numbers, I've crunched them. The Elio front tires at 135/80 R15 and the rear tire at 175/65 R15 are almost the same diameter... almost.
Front: 135 millimeters wide changed to inches is 5.315 inches. The profile 80 means that the tire is 80% as tall as it is wide... 5.315" X .80 = 4.252" Now, that's the measurement from the road to the rim. The rim is 15"... So, 4.252" + 15" + 4.252 = 23.504" outside diameter . Now, the rear... I'll save the explanations. 17.5cm=6.88976" ... 6.88976" x .65 = 4.47835"... 4.478" + 4.478" + 15" = 23.956" = 24" outside diameter.
So, with a diameter that is off by 1/2 inch, if you have to carry a spare, make it one of the front ones. They are smaller, lighter, and it won't affect much putting one on the back long enough to be able to repair/replace the bad one.
I was going to figure out the percentage smaller so I'd know how off the speedometer would be till I realized that will run off the transmission and the front tires.
