Where do they get scratched? I've heard about this before but can't see how a rim can get scratched in a tyre change.The tyre machine clamps the rims externaly,and most motorcycle adapters these days are a plastic material where they touch the rim,and the tyre lifts off the rim from the outside too....so how does the rim get scratched?
A lot of motor vehicle components these days are designed to go together,no thought or atempt of thought goes into how they come apart if it is beyond the design life of the component....but tyres are designed to be changed.Show us some pictures....I want to see the damage.
