What is the benefit of arch rolling? What is it? And what does it involve?

I fitted 17's only rub on full lock but a few have suggested arch rolling

just gives more room for the wheels afaik

Cool cheers! Worth the money just to get rid of the slight rubbing on full lock or a waste of time for so little benefit??

Slight rubbing on full lock :nutter: Not worth it imo

Its probably rubbing on the inner side of the wheel, and not on the arch. Its likely it won't make any difference at all

It rubs on the rubbery-plastic arch liner, mine used to do it and doesn't really cause any problems

Take the wheel off and you'll see marks on the liner where its rubbed.....

yeah,mine used to rub aswell with 17s on full lock but will gradually disappear on usage so it would be a waste of money to get them rolled.
