More than likely they will fit fine, most aftermarket wheels are ordered
with a smaller backspace, I have 3" I think, by 8" wide, this pushes the
tires out and away from the frame, and adds more stability with a wider
stance.
You will want some wider tires also to go with those 8" wide wheels, some
have put a 235 wide tire on those, but I think that's stretching the tire too
much, IMO, but this is your ride, you can make that decision
