Here is how mine fit. 305/70/17 on stock Rubicon wheels.
Clearance of brake light. Your's should be a bit shorter.
Bottom of mine barely rubs, but fits. Your's should just clear.
Your's will also fit further away from the tailgate, since you have more backspace. Mine just fit and has the bumpstops smashed pretty good to get the lugs tight. I have since added a Smittybuilt adapter bracket, which moved it up and out about 1 1/2".
