With prepared fender edges it is no problem to use a 205 40 tyre on 7,5 or 8x17 wheels!

Mounted on the 8x17 you have a little bit more tyre stretch...

Both possible.

195/40R17 is just to less load index...



no problem at all, but you have to look at your car.

Building tolerances on the axle, tolerances at all on tires and tolerances on rims have to be seen mounted.

However, get the smaller tires and have a look, what to do on the front axle. the rear axle should be no problem, because in your case it is a syncro.
