This is a list I got from discount tire some may requiere purchase of new wheels)... but will this have any friction with the car?

Simple answer to "Will they fit?" is Yes. Someone is using their calculator to retain near-stock circumference for speedometer accuracy.

More rambling answer below.

Plus Zero
175/70-13 Yes...almost exact same circumference for speedo accuracy. 20mm (25mm is = 1 inch) wider. Recommended wheel width 5.0 to 6.0"

Plus One
165/65-14 Again, almost right on for circumference.
175/65-14 Same as /\ basically just 10mm wider
185/60-14 Mirrors the stock 155/80R13 circumference. 35mm wider patch
195/55-14 Almost right on circumference with stock 155/80R13...40mm wider patch. *(I have 195/60R15 on high offset 6.5" wide wheels currently on rear of 1992 stock suspension with no rub issues. Same tire/wheel scrubbed heavy on the front of this vehicle. I went with 185/60R15 tires on those same wheels to solve the scrub so that's revealing the limitations - 10mm diff - pretty close for stock suspension)

Plus Two
175/55-15 Again, you are keeping very close to stock circumference even though you went up 2" in wheel diameter. Less sidewall, more tread width.
185/55-15 Same almost as /\ wider patch keeping same profile sidewall. There is slight diff because of "aspect ratio".
195/50-15 Very close to stock overall diameter. Wider patch, less sidewall. May get scrub on the front especially in moderate to hard turns or climbing curb/drives in turns.

Plus Three
195/45-16 Close but slightly larger overall height...difference of speedo only .5 mph. Not certain but you may encounter rub issues on the front.

A primer on tire sizing you may already know but for someone who does not:

For example, 185/60R15

The first number means that the tire is 185 mm at its section width--that is, from the outside of the tire wall all the way across to the outside of the opposite wall.
The second number (after the slash) is the aspect ratio of height to width. Height is measured from the inner-tire circumference to the top of the tread, the part of the tire surface that comes in contact with the road. In the example, the tire's height is 60 percent of the width. The smaller the aspect ratio number is, the wider and shorter the tire will be.
The third number is the rim size. Standards note the measurement of width and aspect ratio in millimeters but the rim size in inches...go figure.


Now what will change things greatly is the offset of the new wheels. The offset can bring your tires out toward the edge of the fender (and beyond) or in. In most cases front wheel drive cars are going to be looking at high (H) offsets. 35 to 40mm. Keep in mind less offset brings the wheel/tire OUT toward the edge of the fender while higher offset places the wheel/tire in toward struts.

Also, suspension mods will change this as well and as mwebb (who is running 185/60R15) has previously noted elsewhere...tire brand/manufacturers will also be slightly different even for the same posted sizes.

It has been noted that the "rubber band" tires, or the sizes that have very little sidewall produce a less than desirable ride in our little lightweight sleds. By utilizing a lower aspect ratio tire, you can increase rim diameter. I believe I read a recently acquired Metro of the second generation flavor had 17" wheels on it and it looks awesome. You'll have to decide for your own ride & comfort. More sidewall, more ability to flex somewhat.

Edit: Also, the above mostly talks about my experience on a '92 Metro 4 door hatch. I forgot to mention I also have a '00 sedan (your profile mentions you have a '99) that I went with 185/60R15 all around and no issues outside of a 4.3% speedo error which I calculate into my MPG figures.
