Hi Rich, sorry to be a pest, S3 tyres/wheels choice is a nightmare, so many questions if you don’t mind...
Cheers Rich
NO. You have to go on the tyre manufacturers web site and read the rim specs. No 235/85 has ever been OK for a 5" rim. Some years back Cooper tires listed 5.5" as "optional" but recommended 6". I checked all the sites I could find data on prior to getting rid od of my 5.5" (LWB) rims and not a single one (inc Cooper) now list 5.5" as OK. They all list 6" minimum and 6.5 recommended. There are quite a few people running 235s on 5.5" rims but it looks like the manufacturers no longer support this. As I "self MOT" I ditched the 5.5" and bought 6.5" and I must say the 235s sit much better and drive better on the wider rim. All you can fit on a 5" is 6.00R16 or 205. I run 5" rims on my trailer and they are very narrow, almost no decent tyre choice.
I would doubt it, I run 750's on wolf rims in my series 3 which should in theory be about the same size and they are fine. (Please excuse the leaking fwh)
