Why not work out the rolling radius?

With 265/40 rears then 235/40 fronts will be about 3.6% smaller i.e. have to rotate faster to keep up whereas the 235/45 fronts will have almost exactly the same diameter as the rear the difference being about 0.06% i.e. nothing to worry about.

I know which I would fit but of course whether any of these will go under your arches only you can tell because you are the only one that knows what modifications you have made and how your car sits on its non-standard springs.
