The KMC Slides do look great in 22s and I'm looking at these matched to some Toyo AT tires for a bit of that rugged look. I find the 24s and up to start looking like wagon wheels (bad proportions).
I'm also considering XD Addicts in 20" form matched to the Toyo AT2s. The tough thing is there aren't many proper looking black wheels out there that fit.
Don't have a Tahoe sample so here's the best I can do in 20s:
The only other route I'm considering is going with forged multi-piece wheels, though I'm weary of them not simply due to cost, but some of them vibrate in the rain (a case of glossy brochures taking priority over R&D).
