Rear quarter lip mods?

I have found the 275 tires on my Duster are rubbing, either from passengers in the back, or the springs settling enough to allow contact on dips and bumps .
Just wondering if I want trim or roll the edges, and what is the best way to do either.
I heard from another car guy there is a tool that attaches to your hubs to roll them? News to me.
How else to go about rolling them?
If I decide to trim them instead, what's the best method?
Also contemplating +2" springs, I have Espo +1" now...but wanted to explore all options.

The damage to my tires is not bad yet, just enough to royally piss me off.
