20 inch OHM wheels bring concert-hall presence to luxury sedans and EVs, and the 20" fitments stocked here come from the LIGHTNING and PROTON lines. Both are monoblock designs, and at this diameter you get a clean canvas for either a stealthy blacked-out look or a brighter, mirror-faced finish.

Why 20-inch OHM wheels work so well
Twenty inches is the sweet spot for many modern luxury platforms: large enough to fill the arch and showcase the spoke design, while still leaving room for a comfortable tire sidewall. OHM concentrates on clean, performance-leaning patterns, and the two 20" models here are both monoblock wheels — forged or cast from a single piece for a straightforward, structurally simple build.

Which OHM models & finishes come in 20-inch
Two models are offered at this diameter:
OHM LIGHTNING
A monoblock available in Gloss Black and Gloss Gunmetal. The LIGHTNING also spans 18 through 22 inches if you want to size up or down — see the 21" OHM and 22" OHM options. A representative example is the OHM LIGHTNING 5x114.3 18x8.5 +30 Gloss Black.
OHM PROTON
Also a monoblock, finished in Gloss Black or Silver w/ Mirror Face. The PROTON covers 17 through 22 inches; the OHM PROTON 5x105 17x6.5 +45 Gloss Black shows the smaller end of that range.
If a larger-and-bolder setup appeals, the OHM AMP monoblock arrives at 21" and 22" — for instance the OHM AMP 5x120 21x10.5 +30 Matte Gunmetal in Matte Black, Matte Gunmetal, or Silver Machined.
Fitment coverage
Across these OHM models the bolt patterns stocked are 5x105, 5x114.3, and 5x120. The LIGHTNING is offered in 5x114.3 and 5x120, two of the most common modern luxury and EV patterns. The PROTON adds 5x105 alongside those two. Always confirm the exact diameter, width, offset, and bolt pattern against your specific vehicle before ordering, since fitment depends on the trim and suspension you're running.
How to choose your 20-inch OHM set
Start with your bolt pattern, then pick the look. For a fully murdered-out stance, the Gloss Black LIGHTNING or PROTON is the move; for contrast and brightness, the PROTON in Silver w/ Mirror Face stands out. Prefer a softer, satin tone? Compare the gunmetal options. Confirm width and offset for your platform, and remember that going to 21" or 22" changes both the look and the tire choices available.
