Will 33"s on a 12" rim, fit on a 2wd 2012 Ram with a 2.5 leveling kit, without rubbing?

 

Thats a wide *** wheel.
People will need more information.
Like 33x? And offset of the wheel.
What may fit they're truck at a 33x10.5 may not work on your 33x14.5.
What may fit on a 10" wheel may not fit with a 12" wheel.
A 12.5 wide tire on a 12" wide wheel is kinda goofy.
Look like those kids with the low rider cars and the too small a tire on wide wheels.
Imagine trying to seat a bead on that and having it hold air without it wanting to fall off.
12" Wide. Wow.
I had made custom 16" wide but I was running 44x21.5x16 Tires on a 4x4 off road only.

 

Regular 33/12.50, on a stock 2012 Ram 1500. People run 12" rims all of the 33"s all the time, looks just fine. Not sure of the offset, but I'm looking at a very deep dish rim.

 

Well what looks good to one...
Anyways, 12" offers no wheel protection when hitting rocks or in your case curbs. A 10" wide allows the tire to rub first. Possibly saving your wheel.
A 12" offers no side pressure impact resistance to keep the wheel on the bead as a 10" would. Especially if a tire is low.
Its stretched out already to hold it in place. At low air it wants to collapse and lose the bead seal.
Just saying. May look cool but your really starting to push the safety aspect of things.
But it can be done.
Best to find a shop that will allow a test fit. Then you can know for certain if it will work.
