Need Help With Backspacing!
A bit of rubbing is hardly unusual and not much to be worried about when flexing. But if you're stuffing your tires so deep into your fenders that it prevents them from turning, that's not something backspacing & wheel width will fix.
With 9" wide wheels, you're gonna need additional backspacing to reduce rubbing and as backspacing goes up, so does stress on mechanical components, leading to accelerated wear.
Also, wider wheels tends to lead to problems with tire beads popping when airing down and it pushes the weakest part of the sidewall out into rocks & roots.
All of this does not account for looks, that being entirely subjective. If you look at how a serious trail rig for your favorite wheeling spots is equipped and model your choices after that, you'll be good to go. But if you make decisions with a bias towards looks (when it runs counter to the performance of that component) then you're on your own.
Oh and DO NOT ask for tire suggestions. For every 10 people you ask, you'll get 8!different opinions. Just observe what others are using that works and those a try. If you hit on a good set that performs well from the start, consider yourself lucky.
