How much space does removing flares create?

I can't tell since the flares are still on there, but do I gain any extra clearance by removing them (for bigger wheels)? If so, how much?

 

There's a little room to be had, but probably no more than 3/4". But then you have all the holes to deal with...

 

I don't mind the holes actually. I'll eventually get some glass later down the line.

 

remove them and then cut the shit out the fenders and get as much as u need then

 

You won't get much clearance. My bushwacker flares are pretty much flush against the inner fender/body of the truck. When I clearanced, I just cut a little of the flare, the pinch weld, and the lower part of the quarter panel to get my clearance...
