If I were to buy any wheel with a 4.5 backspacing with 33 x 12.50 r17 will it fit a 09 jk withouth a lift or spacers and will their be any rubbing issues,thanks in advance.

 

The backspacing just ensures that you don't have interference issues in the axis along the axle, so you will not need spacers

The second factor is the diameter of the tire. 32" tires clear with no rubbing, but with 33's you may have minor rubbing with the wheels turned. How much rubbing depends on which 33" tire you are considering since there can be almost 1" variance between different brands.

Lot of this information is in the FAQ.

I ran that set up for about 6 month on road you will be fine off road if you start flexing you will rub the fenders

 

I got 33x12.5x15 with 4"bs and no lift, no rub. Turned wheels from lock to lock and no rub but i have not had it off road yet like this. I can let you know after next weekend maybe.
