I’m running 275/70s so they are about 32.5” tall. The black finish never even dawned on me. Personal preference is I don’t like matte finish wheels because as they age they tend to get a chalky look from what I’ve seen especially on salty roads, polished can always be repolished. Not trying to sway your choice but give thoughts to consider. Unsure what price you’ve found but here they are on summits site for the exact procomp that I have.
