Can you clarify where and when you are rubbing?
All tire brands are different. The sidewall thickness and shape can vary slightly.
If the rubbing isn't bad (which it shouldn't be with that size) I'd keep em on.
If you notice continual rubbing daily, which will wear down your liner, I'd sell them and swap them for a different brand tire.
You can't go wrong with a square setup, maybe something along the lines of 265/30/19 F and 265/35/19 R.
