Thought I'd update the thread. So I went to a recommended garage and they weren't concerned over anything really, but then that could be turning business away so take that with a pinch of salt. They didn't have any exact tyres and ordered a tyre called Michelin Primacy 4 Outside Total Performance and swapped it for the punctured low thread front left. After driving throughout the winter I've not noticed any difference, but then the advice on the thread has already pointed out the potential problems.
One thing though. I'd had a previous issue with the car tyre deflation warning constantly going off and that eventually stopped. But now after the tyre change it's now back to every long trip.
