Bulge on Goodyear run flat

[Louis Balfour]

The main dealer fitted two new Goodyear run flats on the front of my Ghost two years ago. I have not kerbed them at all and don't bump up kerbs. Yesterday, I noticed that one was bulging.

I've also just Googled Goodyear Run-Flat bulge and come up with a few pages of results.

Does anyone know anything about these tyres? Are they, as I suspect, problematic?

TIA

Its really common for runflats to do this regardless of car, tts just the roads in general, all you can do is replace it. They are a dangerous defect and fail when it comes to an MOT.

Why are RFs more prone to it?

Ah, may be a case of suck it up then.
