Default Can I use P185 70R14 tire on my 1995 Camry V6

I have four snow tires which are P185 70R14(From my 1987 Camry). Can I
use it on my 1995 Camry V6 in winter time? The current tires are P205
60R15. Thanks.

If the wheels fit. Obviously, you can't mount 14" tires on 15" rims.

You will notice a big difference in handling and the speedo will be off.
But, the skinnier tires will give you a better 'cut' in snow.

My P185 70R14 tires are on rim. I did some research on internet.

My conclusion is: I can use the old winter 185 70R14 tires (on old rim)
but it will affect the mileage because of the smaller size.

Here is an article form Tirerack.com:

Tire Rack is a nice source for this kind of stuff. As long as the bolt
pattern matches up there should be no problem.

It won't affect the speedometer much at all.
The 14" tires are only 1/2" , or 2% smaller in
diameter than the 15" tires. This would only be approx
1.5 mph difference at 70 mph.
I doubt your gas mileage would suffer any.

It's the circumference that makes the difference in MPH

I am not sure, (cause I haven't been a speedo guy for about five years
now), what the actual differnce would be. However, I do believe it
would have to turn a bit faster than that described. My math mind is
out of pocket at this time, and I am pulling this up from a tired set
of DIMMS...................although It's feasible to just run it
against another vehicle that is trusted to be accurate, and just
adjust your thinking to certain miile per hour settings
differences...........I have even seen folks mark on the speedo lens
with a sharpee to show the marks to keep em outta trouble. I recomend
tape or electrostatic film to mark on, unless you can change the lense
yourself later.

The above poster may be right, but it just doesn;t feel right to me.

Math explanations are simply not viable from me right now........LOL

Oops, I forgot to mention that the MPH you will read will be higher
with smaller tires, not the reverse...............

Smaller tires are actually safer to "hope" against because the speedo
will read faster than you are going.

Circumference , diameter ...can't have more of one without the
other. A tire has to be larger in diameter to have a larger
circumference.
I suppose I should have done the math , so here it is.

First , what those numbers and letters mean.

P = Passenger car
185 = width of tire in mm
70 = aspect ratio. The distance from the bead of the tire to the top
of the tread would be 70% of the width.
R = radial
15 = wheel size of course

There is usually another letter such as H or V and so on which is the
speed rating of the tire.
------------------------------------------------------------------------------------------

P185 70R14
185 mm x 70% = 129.5mm distance from the bead to top of tread.
Now we double that to get total bead to top of tread height for top
and bottom.
129.5 mm x 2 = 259 mm / 25.4 = 10.19 inches
wheel size of 14" + 10.19" = 24.19"
24.19 x 3.14 = 75.9" rollout... or circumference.
-------------------------------------------------------------------------------------------
P205 60R15

205 mm x 60%=123 mm x 2 = 246 mm / 25.4 = 9.68 inches
wheel size of 15" + 9.68" = 24.68"
24.68" x 3.14 = 77.5" rollout ....or circumference

So you can see there is approx 2% difference in diameter or
circumference which also equates to 2% difference in indicated
speed. 70 mph x 2% = 1.4 mph. Indicated speed with the smaller
tires would be faster than you are actually traveling.

Please don't attack me for not showing this in formula format , I
preferred doing it the way I did.

Thinker skin Ken,.............I said you may be right. It just didn't
feel right to me as I used to adjust/repair speedos, and had to
measure out rollout and such everytime so as to make an accurate
setting when finished.
I apologize if it seemed as an attack. It was not meant to be at all.
Just a clarification to the original poster.

I didn't think it was an attack. Sorry if I made it sound
that way. I too was just trying to clarify my post. :-)
