do 195 65 R15 tires can fit on a OEM rims which have a previous tire of 175_65_R15?

 

Tire size calculator

Technically, the should fit as they are both 15" wheels. you are putting a 20mm wider tire on (10mm/side) and adding a full inch in diameter (Jacking the car up 1/2" higher off the ground)

They'll throw your speedometer off by 3mph too.

I run 185/65/15 snow tires so I get 1/4" lift for better snow clearance but that's only for the winter.

Again, they'll probably fit (technically) but I wouldn't recommend it, especially if they are for all year driving.

You want narrower tires in the winter anyways if you are anticipating snow.
