Gareth,
Please for give my comment.😀 However I have to strongly disagree with your own comments. Given the picture provided above you can clearly see where and how the damage is displayed and therefore although I accept that the car does require to be taken to a trusted tyre expert; this does not mean that this forum cannot be utilised to give reasonable advice hence the reason why such a forum exists.
I have been in the car club seen and actually run a car club myself and have done for since 2002 and the car forum community have the technical ability to share views,opinions and advice not such topics. 😀
