snow tire fitment?

Aside from what I assume is a sidewall that's too big, no. They'll mount, balance and drive fine, but your speedo may be off a bit.
 
According to the calculator it should be a 23.7" tire versus the stock 23". I doubt that will cause an issue besides your speedo reading a little low.
 
It may rub at the rear tires when the suspension compresses.i think I tried a 65 and it rubbed quite a bit. I will check and get back.
 
It may work. I tried 185-65-15 and they rubbed pretty bad. The bulges at the rear of the rear tires. I tried that size because it was the only one available in the tire I preferred.
 
I suspect the 185/60's will be OK...here's how the diameters break down:

185/55-15: 23.0in
185/60-15: 23.7in
185/65-15: 24.5in
 
The tyres on my car is standard deliverd by Mazda. I have 185/55-15 on my snow/winter tyres.
On the summer wheels I have standard 195/45-16.
