What tires will fit on these wheels, tire size question Options

Hi, i have read some other posts saying that i can replace my 165 15 tires with 195 65 r15's. I was wondering if anyone has the same wheels as me with the 195 tire size. Mine already seem close to the wheel arch lip in the rear. But there is still enough clearance to fit my fingers between. I attatched a pic of my car. Which wheels are these? Should the 195's fit and not rub. Thanks

So i measured the offset of my rims last night and i believe they have the 4" offset. I can get my fingers up between the fender and the tire, but that is about it. Im not sure if bigger tires would clear when the wheel moves up into the wheel well. It does look like there is 15 or so mm between the tire and fender lip. So should i just look for different rims? Or should i try and squeze some 195s on there? How would i go about rolling up the lip inside the wheel well without damaging the fender? Any ideas. Im not opposed to getting new rims, just dont want to wait that long.
