According to a used wheel dealer, the 14" wheels from a Mitsubishi Galant will bolt onto a Metro/Swift and for 15", the wheels from a Hyundai Elantra will bolt on. I intend to experiment with bigger diameter skinny tires in an attempt to experiment with achieving taller gearing. Has anyone ever tried a 155/80 15" tire on a Metro? Has anyone ever tried any skinny 14" tires?

That's a pretty tall tire, you may run into clearance issues. What are you putting it on? If your car came with 13" wheels, it's a 9% difference. If your car came with 12" wheels, it's a 17% difference, WAY too much.

are there any tires skinny enough to make this fuel efficent on 14 or 15 rims? also i seen an Aveo that had 14tires. Those will probably fit.

I managed to put 155/60/15's on my 86 Sprint using some factory Honda Accord wheels (15x5.5 50mm offset). I couldn't find anything narrower. They fit pretty darn well considering the wheels are 1.5 inches wider than stock. I can barely fit the end of my little finger between the rim and the strut on the inside and they sit about right on the outer edge. I haven't had a chance to see if there's an MPG change yet but they'll take 44psi and the car handles MUCH better! I didn't trust the 12' tires anymore. (Look at the 'Smooth hubcaps' thread for pictures why.)
If you could find a 15x5 wheel with the right offset then you could use the 145/65/15's that are sometimes available. Availability on the 145s is sketchy but the 155's are usually available--Tirerack.com
The 155R12's are 21.8 inches in diameter
The 155/60/15's are 22.3 inches a little larger diameter but in the right range. The 145/65/15's were actually a little larger still.
With the 15's on, my car could stand to be lowered a little. Not sure how to do that with rear leafs other than spacers... or maybe don't bother.
Here it is:

I took a quick look on EBay for the Elantra 15" wheels and all the aluminum ones were 6 inches wide. That's too wide for a Mk1 Sprint but maybe it would work for a later car? The steel Elantra wheels were 15x5.5 which would work better. No idea what the offset/backspacing is like. If anyone finds a 15x5 or narrower 15 that fits, please post what you found!

Ok, I'm pretty excited now!
I recently turned in my 155/R12's and swapped them for the 155/60/15's w/40 psi as stated above.
Even before MPG numbers, I LOVED the way the car handles by comparison-- it's a LOT tighter without being harsh at all. It got rid of 85% of the wobbley feely of the car. Feels much safer.
I finally got some MPG numbers-- not a great test since it was only out of 175 miles, but still, it's a start.
My previous BEST was averaging 48.8 MPG on a 1000+ mile trip up to Canada.
My AVERAGE for normal driving of around town/short freeway trips was about 39 MPG.
My first calculation on the new tires was a mix of short trips and one 30 mile freeway run and got 45.5 MPG so I would call that an improvement! I can't wait to see what a freeway-only trip gets!
I was a little worried that I'd get worse mileage since the wheels may be heavier than the stock ones, but it doesn't seem to be causing a problem. The new wheels are probably a little more aerodynamic and maybe that makes up for it. I think I'll try bumping the pressure up to 45 psi and see how that feels.
Anyway, if you're tempted to change to a larger rim or need new tires anyway, I would totally recommend this setup!
Cheers!

All Elantra wheels (01-06) are a 46mm offset, stees are 15x5.5. That's my DD.

I did some measuring just to see how big the changes were going from 12's to 15's
The tire specs listed on Tirerack.com were a little off.

.........................SPECS.....MEASURED......WIDTH...............WEIGHT: wheel+tire
155R12 (new).......21.8 in.......21.1 in .......... ---.................22 lbs on stock rim
155/60/15 (new)...22.3 in.......22.3 in.......around 1" wider.....29 lbs on 7 spoke honda alloy
..(I'll try to get an actual measurement for the width)............(the ones on the gold Sprint)

Bummer about the extra weight: around 7 or 8 lbs per wheel. The car doesn't feel slower and so far it doesn't seem to hurt the mileage:
I had to recalculate my MPG since the speedo error is larger than I thought so it came out to around 47 MPG and that was with a fair quantity of city miles. Again, too short of a test for much confidence in the numbers. I'll try to get more accurate fuel numbers, but until then, Yeehaw!

GOOD CHOICE! :D
i want to do the same.

http://www.miata.net/garage/tirecalc.html
says you have 5.4% greater circumference

your Tirerack diameters indicate +5.7% and may be more accurate if based on the actual tire brands.

you must lose some of this benefit due to the wider tire and larger wheel, but how much?
acceleration will lower but max, speed will increase.

i meant
your actual tire diameters indicate +5.7% .

BTW
if old was 39mpg, new would be 41+/- ?
and at $3.75 /gal you will save $48.75 in 10k miles?
AND IT HANDLES BETTER :D

I tried it again and I like it again. Just so as not to confuse people from the thread title, these wheels I'm using on both the red 85 and gold 87 Sprints came from HONDA ACCORDS not the Mitsus or Hyundais.
These 7 spoke wheels MIGHT stick out fractionally more beyond the tire than the other 'pan style' Honda wheels but it's not bad. It may be that the gaps between the spokes just make it LOOK like they stick out more? For wider tires, I like the look of the 7 spokes better, but on a Sprint with the skinny tires, I might like the pan style ones better. The pans definitely fit the 85-86 styling better. Backspacing is supposed to be the same judging by the casting marks on the wheels, and that looks to be accurate.

Now I have to look into lowering them an inch or inch-and-a-half.

I started running a set of 185/65/14 on my 98 swift since my tire shop quit ordering any good 13" tires so fire i have been verry happy with the performance lost a little bit of low end speed but not bad, have not taken the time to check the mileage yet but the speedo is about 1 per 10 mph off according to the gps and rides much smoother now.
