Problem with runflats is that people think they can run them flat and get away with it. Sure you can drive on them when de-inflated or on very low pressure for about 50 odd miles --maybe more - but in the process they are irreparably damaged This may not be immediately apparent but the damage is there all the same . Your tyre has all the appearance of a runflat that has been "run flat " sometime in the past before you bought the car.
