Thanks for the advice, and certainly justified after some of my mechanical exploits.
The tyres are the same width as standard so whilst the height is different it's not significant enough to cause any issues with contacting the wing, or anything else, on full lock.
My speedometer setting isn't standard, whatever that may be, as it's now on version 3 of the software after being reset at the factory. ( It used to under read the speed which was not only illegal but potentially licence threatening). I checked the speed against gps before changing the tyres and it over stated the speed by 8% so the change in rolling diameter will improve the accuracy of my speedo, but definitely worth checking this for anyone thinking of making the change.
