With the 6" wide 15" wheels and the 195 width tyres the car is almost over tyred. There does not seem to be much point in fitting wider tyres unless the engine power has been significantly increased; something really only possible on a new GDI engined Plus 4 by changing the engine.

Putting 6.5" wheels would probably mean changing to 205 width tyres. The result would be heavier steering and more grip which would make the car handle differently.

There are a lot of Plus 4 cars which have actually been specified with narrower 5" wheels and taller tyres. The look is more classic, the steering lighter, and the car handles exceptionally well.

Perhaps it is better to try to drive a couple of cars fitted with different wheels and tyres before you decide.
