Interesting to follow this discussion, and in particular the reference to insurance issues switching to other tyre dimensions. So I just wanted to share my experience from Sweden.
TPMS is not mandatory in Sweden and I run winter tyres without TPMS system and it works perfectly, apart from the annoying warning signal on the dashboard.
Wintertyres are mandatory in Sweden and there are numerous tests in scandinavian countries on which is the best winter tyre. And one thing is for sure, the OEM Toyos are rubbish (I would say lethal) in winter and also illegal is Sweden. So saying that the insurance company require OEM tyres is at least illegal (and also stupid) in Scandinavian countries.
In winter up north when there is a lot of snow and not so many snowploughs you want skinny tyres in winter. I run 215/70-16 (the skinniest I could find) in winter and 225/55-18 in summer. No problem whatsoever.
I have a hard time seeing the PHEV knowing the diameter of a tyre as long as all tyres on the car are of same dimension. You could probably run 20cm smaller diameter (if it fits) and the car would not know it. The car would not behave well at all but the sw would not know. IF the car should recognise the diameter it must either have a diameter sensor or compare GPS speed with tyre rotation. I do not think it does either, but it may surprise in this area (perhaps.
So running 235/55-18 would not be a problem for the car sw. at all. Check that it does not hit the wheelwell in sharp turns though.
On the Brittish insurance system I cannot tell, but seeing the comments here it looks like you need to bring some common sense into it. You need good tyres on the car and depending on roadconditions the supplied OEMS are sometimes OK, never excellent and in some conditions (pure winter) absolutely dangerous and lethal, and illegal in Sweden, Finland and Norway.
