I am goin the other direction. Slightly.. Looking at a 10” rim for 33x12.5x18 or 33x13x18. Looks like most “suggested” for a Raptor, 10” wide are -12 or more and 9” wide rims are anywhere from +18 to -12 Looks like The back spaceing changes to help compensate for some of it..? Depending on the rim design. Trying to get the tire/rim right @ the fender lip or up to no more than 1” out side. Unless I miss understand the mechanics of it..? A 10x18 with an offset from +18 to 0 and a 32.5” to 33.7 tall tire should put the tire edge right about where I want it with no rubb8ng as the tire is about a half inch shorter than stock. A -12 offset might work..with the slightly shorter tire diameter..? More reasearch..
