195/60-14 Tires on '02?

Here are the numbers off the Miata calculator for my '02 Prius (top row is stock tires):

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
175/65-14 4.5in 11.5in 23.0in 72.1in 879 0.0%
185/60-14 4.4in 11.4in 22.7in 71.4in 887 -0.9%
195/60-14 4.6in 11.6in 23.2in 72.9in 869 1.1%

My question is (two of them actually):
- What is the stock rim width on the '01-'03 prius? Is it 6"? EDIT - someone told me they are 5".
- Anyone have issues with 195/60-14 tires mounted (e.g. rubbing at full turn or at struts/wheel wells)? EDIT: see my next post

Other comments are also welcome, except the kind of "better stick to stock" without a good explanation. Keep in mind that restating the impact on speed/mpg readings due to diameter/circumference is *not* a good enough explanation to me as it is self-evident and discussed to death, so let's not repeat it here unless you feel you absolutely must

I've pretty much decided on getting the Michelin Pilot Exalto A/S - it is arguably the best performing tire in its class (and I have had it on my Camry for a while and it is indeed great).

Tire Specs for Michelin Pilot Exalto A/S

So my primary concern is if the 195/60-14 size would fit the stock rim width comfortably or not. I can also go for the 185 size that will fit but I'd rather have the 195 size with the resulting slightly larger diameter over stock (my car is too low as it is already). And I will *not* go for 175 width as it is too narrow - I'd like to get a bit more stability/braking out of my tires.

 

Since the local NTB had them in stock and matched the price I had in mind, I had the tires installed today. They are indeed visually fatter than the OEM size but I think do not bulge-out too much in reality. That is if inflated to over 36 PSI (as seen the front is at 41.0 the back is at 37 PSI).

Ride is more quiet and subtle than the Potenzas they replaced, but the Potenzas were at the end of their life, so the comparision is not entirely fare

The only (slight) fittment problem is that the right/passenger tire would rub just a bit when the steering wheel is truned fully clockwise. No rubbing in the other direction or elsewhere.

Remains to be seen how the fuel efficency would be affected. These are max 44 psi rated (vs. 50 for the OEM) but have about 100lb higher load rating than the OEMs. They are also 3lb heavier each.
