Gnasher and a few others have run 8.5 x 19 wheels circa ET45 and 46 so we know that width and offset will fit ok. Keeping a similar rolling diameter using 18” wheels and thus not upsetting the speedo I’d definitely plump for 235/40/18 tyres unless the car was going to be drastically lowered.
225 tyres would just leave the wheel rim too prone to accidental damage.
