Thanks for all the advice received. I phoned my local tyre centre and was told straight away that it would void my insurance if I was to change from run flats to standard? I had finally decided to to with staggered too. going to wait until I actually pick it up now and then sort it out.
As others have said: an absolute crock of bovine excrement!
Get it home then look at one of the on-line tyre suppliers, always good deals to be had.
You may even find you're happy to keep the RFTs until they're worn out.
Think it's mainly 19" wheels that have issues with cracking due to the harder sidewalls on the RFTs.
