235/40/18 Tyres on 8.5" wheel - Mk3 Estate

Good morning all - I promise I have tried but I am loosing the will to live with the search as it is such a common string - The problem is I am trying to research going for a wider tyre on our car with a wider wheel but same size (18)

We have the standard alloys at present on our estate - these are 18x7.5 I think - the standard 18's that come on a 2014 VRS estate - they come with a 225/40/18. The car is presently in having some serious maintenance done so not seen it for good few weeks... new subframe rear, B12 Kit, new Turbo, DMF, Clutch and we have owned this car from almost new and the wife loves it... Can't really fault it or the 120+ K she has done in it but.... Wheels.... We are considering a set of the old Ronal A8 18's -

What I am after is anyone that has run a 235 width on the mk3.. I hoping going for a 235 would give her a little protection from curbs as the same alloys I have seen with 225 seem a little stretched to me and I think she'd be gutted first time she curbed them with any stretch... Will 235's catch the inner arch/strut is my concern?

I suspect rears be fine but looking for any experience with 235's on the mk3.. I am presuming everything else will clear as the Ronal's an very similar to present setup but offset I think will push the wheels out a tad and with the small drop from the Eibach setup but I did not think this would be an issue.... things that concern we are arch scrub loaded up or inner arch liner/interferance...

235 V stretch 225 - We already have the 225's on standard rims but can't help thinking the stretch will catch her out is all.... prob over thinking it but never seen an Mk3 running the old school Ronal's which makes me thing there are issues but these are 18.8x5 112x5 Et 45 - the original fat fives as I know them.

Anyone any advise, experience or know anyone that runs these on anything in the VAG MQB range and can feedback around interference or work needed..

Have a good,

Bobby
