Its all up to the treatment tyre gets fm the dealer, do not forget last year the issues faced by one of our members when his tyres were completely destroyed after a single trip when at the same time another member had fitted the same tyres and by comparison those apeared almost new, best guess then was pour storage and treatment by dealer.
