The key thing is 33x10.5r-15 Narrow fits easy

I also did put my 33x12.5r-15s on the RS for a couple weeks. Because it was hot 100* and I didn't feel like using my HF manual tire changer right then. I did have some minor rubbing at full lock and they might have rubbed if flexed, didn't try it, I was too busy with work and getting ready for CoZu.

The extra weight difference between 10.5" tires on alloy wheels and 12.5" tires on steel is something to consider. Heavy will make you want better shocks and more power. I don't really notice the heavier 12.5" rubber on steel wheels in my 3.4v6 Trooper. But I really noticed the difference on the 2.6 4 cyl RS Trooper
