It is strange as it does not actually touch the bracket,i am guessing that there is enough flexing when hitting bumps that it then comes into contact although it is a pretty solid bracket.The tyre has always had a cover on,the damage is on the inside so it's not UV damage.The shop that fitted a new one suggested that it my still be covered by some warranty but i did not pursue that.
I just want owners to be aware that there may be a hidden issue with their spares.
