I'm wondering the same thing, although I still have the stock tires on. Did you have to do anything to the spare tire mount to fit you 33's?Hey members. Put in a Curt Class III 13392 hitch receiver today and after putting the ball mount in I’m wondering if I need to get a receiver extension. My tire size is 33x12.5R17 if it’s relevant. Thx!
Andrew, you'll want to hook up the trailer you're towing, and test the bumper-to-tongue clearance when in a tight turn. You can also observe if a lower hitch draw bar is required in order to maintain a level trailer connection.Put in a Curt Class III 13392 hitch receiver today and after putting the ball mount in I’m wondering if I need to get a receiver extension.

Depends heavily on what trailer you are going to tow. Uhauls and boats are going to want about a 18.5” ball height, but smaller utility trailers may be lower. If you have the trailer you want to use, it’s best to measure the drop and buy that specific drop hitch. (Measure to the top of the receiver tube opening and subtract the desired tongue height).@atso
I'd return that Curt hitch and get a refund....... unless all you want it for is to carry a bicycle. If that is all you want to do, go buy a hitch extender for use with that Curt 4".
Actually, for trailer towing, you need to buy a decent adjustable hitch.... the non-adjustable 4" Curt hitch you have is not going to do the job for you.
That non-adjustable, 4 inch hitch on a Rubicon, especially, is not going to work with most trailers, if not all.
On a Rubicon, because of how tall it is.... will require a hitch with at least a 6" drop ......and more often then not an 8" drop will be needed for proper/safe trailer towing
Buy a decent 8-10" adjustable drop hitch... You'll then have the choice of different drops and you will see the ball out from under the spare a bit, which is a must.. avoid hitch extenders...

@atsoawesome thx for the feedback everyone. I’ll take Rhinebeck’s advice and look for a longer adjustable ball mount rather than have 5 lying around. Yeah primarily it’ll used for towing and maybe bike or ski rack down the road.
