You now have a 33" tire, so a good simple solution is a used Rebel wheel/tire which are 33" from factory, they should fit with no issues or even a Rebel spare, which should be noted is slightly smaller than the stock Duratracs Rebels come.
When you go to 34/35", you may need to deflate the tire a bit, some have installed even larger spares by cutting the backend of the tow hitch that is inside that space to give more clearance. But that's way beyond where you are now with your new tires.
Not sure your area, but moparleo51 has a Rebel spare in Ohio. If not close, I would check your local Craigslist and Offerup first before you buy a new wheel/tire of similar size.
