326's And Tyre Sizes

Morning all.
I know there has been masses of discussion on 326 tyre sizes before, most of which I've read but I'm still left unsure of what to do. I admit I only have a very basic understanding of wheel/tyre sizes so I'm guessing that's the biggest reason for my confusion.
What I have understood is that the run flats have to go as was the case with my E85 so they're going but there seems to be a recommendation to increase the tyre profiles for a more comfortable ride and to protect the wheels. That's where my confusion lies!
It seems most agree that the rears can happily go from 255/30/19 to 255/35/19 and I'm happy with that but what happens with the fronts?
Apparently, from what I've read, 225/40/19 is one option but might cause rubbing, maybe only on full lock and maybe only with certain tyre brands but it's a possibility and definitely something I want to avoid.
Another option I've seen mentioned is 215/40/19 but will this make the front tyres look stretched?
The third option would be to leave them at 225/35/19 and that is my preferred option but will that be OK with the increase on the rears?
Sorry for bringing this whole topic up again but I'm getting close to needing new tyres so need to get my head around it.

Thanks in advance for your help.
 
I went with 235/19 for the fronts with which I'm very pleased, they give a slight profile increase and look just right, and no rubbing whatsoever.

Am I correct in assuming this is still with the 35 profile so 235/35/19?

I just fitted 245 35 19 to rear of 326s & stayed with 225 35 fronts.

Am I right that the width drop to 245 decreases the sidewall (and therefore, rolling circumference) change compared to the 255/35/19 change so the difference from standard is reduced?

Thank you for your replies. Just trying to get my head round the best way to go :-?

Width has dropped yes from 255 but profile up from 30 to 35 so a increased comfort & wheel protection .
 
Profile is a percentage of width so a 245/35 is only ever so slightly greater than a 255/30.

I went 235/35 and 255/35. No rubbing even lowered on Eibachs.
