Do I need to tell my insurer if I fit run-flat tyres?

I'd like to fit run-flat tyres to Mitsubishi ASX. The standard tyres size is 225/55/18 but run-flats don't come in that size. My local tyre dealer recommends 245/45/18 which are available as run-flats. Would I need to tell my insurance company?

No, you do not need to inform your insurer. As long as the tyres are legal and meet OE standards then you are fine.
