Can I replace my 185 tires with 195?

and other systems. You may want to talk to a dealer or a master mechanic.
because the 185 or 195 is the height of the tire in centimeters.
I hope this helps you out.

I didn't read the original article, but the hight of the tire is never
expressed
as a millimeter measurement. In fact, it's never expressed as a explicit
number. Tires are given in terms of tread width, aspect ratio, and inner
diameter:
185 / 70 - 13
the 70 means that the sidewall is 70% of the tire width and the 13 means it
will fit a 13 inch diameter wheel.
Going from a 185 to a 195 tire shouldn't be a problem (a little bit wider)
if you go down in aspect ratio. In other words, if you go from the above
example of 185/70-13 to a 195 tire, it'll be something like a 195/60-13.
That'll maintain the same outside diameter (within 1%) of stock and
there won't be any speedometer changes necessary.
Go to a tire and wheel shop and they can explain and show you what I
mean.

Incorrect. A tire that is labeled as "P205 60R14" is a passenger car tire
(P) that has a nominal section width (cross section) of 205 millimeters
(205), a nominal sidewall height that is 60% of the section width (60), is
a radial construction (R) and is made for a 14" rim (14). There are
variations including speed ratings (e.g. ...60ZR...) and some tires
nowadays don't include some things like the R (radial) spec, but the
basics are here.
If you went from a 185 to a 195 and stayed at the same series tire, then
yes there would be an increase in loaded radius. However, when increasing
the section width of a tire, generally you can go to the next lower series
and end up at the same height. You can also change rim diameter and do
the same thing. It's called "plus-1" or "plus-2" etc. If for example
I took my Z24 and mounted some cool 16 inch Momo rims, I'd probably
have to go from the current P205 60R14 to something like a P225 40R16 or
even a P225 35R16 (if they made such a thing).
In answer to the original poster's question, go ahead and change the
damn tires. It'll be fine. If you were going from a 185 to a 225 or
something I'd be concerned then!

WHAT????
185 and 195 refer to the WIDTH of the tire. By appropriately adjusting the
sidewall height, you shouldn't have any problem.
Example: I have 185/60HR14's on my car. 195/55HR14's would be close to the
same height since you are decreasing sidewall percentage height, but the
sidewall height is based on the width (something like 195 wide, 55% of 195
tall). Oh, and tires are measured in MILLIMETERS. Do you not realize how wide
195 centimeters is?

as recommanded (not my choice though, bought the car used and it came like
this.) So I would think it should not be a big problem. The car looks
better in the bigger tires. I still get 30mpg, beat the EPA 29mpg. BTW
my car is 89 Corsica.
I calculated the increase in diameter:
185/75R14: diameter=63.17 cm
195/75R14: diameter=64.67 cm
So it shouldn't be a big factor concerning the speedo.
When speedo says 65, I am actually doing 66.5. Taking account
that speedo usually is 1-2 miles above actual speed, I might just
be doing 65.

You don't even need to worry about profile with a change as small as
this. Example: 195/60 on a 14 inch rim has a diameter only 2% more than
a 185/60 on the same rim. Most speedos are about 5-10% out in the first
place!

Many tire shops have books which list the actual diameter of different
tires & sizes - it's much easier than working it out.
For instance I was comparing 195-55-14 with 185-60-14 and (depending on
the brand and tread depth) easily saw from my tire dealer's books that
the actual diameters were within about 1/4" - not worth worrying
about as far as the speedo is concerned.
Now, if only I could figure out how to go with a wider tire without the
tire rubbing on suspension parts...

This makes me very confused. 185 cm or 195 cm is 6+ feet.

This is correct for this sizing system. But in the US, truck tires are
available by height, width and rim size... 30X9.50-15.

a straight-ahead. I advocate nothing wider than a 65-series
(aspect ratio) tire for most passenger applications. Will track
straighter and return from turns quicker than a 55 or 45-series,
which is mainly for looks.
