195/65/15 is not only too big re the rim offset but also the rim itself is only allowed up to 185 tyre width. 195/65/15 is often used as an alternative with the standard on Plus 4 models to achieve a little more ground clearance and better filling of the wheel arches, but this happens on the base of wider rims.
I am also very happy with Vedestein T Trac 2 in the size of 165/80/15 and I will get the third set next spring. Unfortunately I have not been able to find 175/75/15 on the internet. You would have to try 175/70/15 to see how that looks visually in diameter.
Here you get an impression on page 3 of the link.
https://www.reifenrechner.at/index....15&2rb=175&2rh=70&2durchm=15The T Trac 2 have very good grip and I don't miss more width except maybe when braking very hard before fast corners. (the 165/80/15 have improved my neuro ABS:) But you get used to the car very well and a good 165/80/15 adds a lot to the overall driving pleasure of a 4/4. Don't worry about 165 widths not performing well. You'll be surprised, and in the wet it's much better than wider tyres anyway concerning the light weight of the car.
