Hi
Thank you for your replies, it seems that there is little to offer at the moment, tyre wise to help prevent reversing scrapes...
I also have Continental 245/40/R18's Neil, on my SC430 and they are due to be replaced soon, so I might just have to carry on looking.
They unfortunately did not help with a very high kerb on one rear wheel😪...
The reviews, on plastic coloured rim protectors from customers are reasons why they should be avoided.
On another forum this was offered as a solution
