Why a 6x139.7 Black Rhino Build Matters
The 6x139.7 pattern (also written 6x5.5) is the workhorse spec behind countless trucks and body-on-frame SUVs, which is exactly the platform Black Rhino's Hard Alloys line is engineered around. Every model here is a monoblock cast design — a single-piece wheel built for the loads and abuse that come with daily towing, trail use and bigger tire packages. Because Black Rhino develops these around real truck and overland applications, the bolt patterns and offsets are purpose-matched to those platforms rather than adapted from a car wheel. You can browse the full Black Rhino Hard Alloys lineup to see how this six-lug group fits into the wider range.
Models & Finishes Offered in 6x139.7
Several Hard Alloys designs carry the 6x139.7 pattern. The 030 comes in Burnt Bronze, Gloss Black and Matte Black, while the 200 is offered in Hyper Silver w/ Machined Face and Matte Black. The trail-focused ARS is available in Sand Black, Sand on Black and Textured Matte Black.
The newer six-lug designs add bolder color play: the BR020 Diamondback in Burnt Bronze, Matte Black and Metallic Blue; the BR021 Mondo in Burnt Bronze, Gloss Silver w/ Mirror Cut Lip, Matte Black w/ Gloss Black Lip and Matte Gunmetal w/ Gloss Gray Lip; the BR022 Bahari, BR023 Xplorer, BR024 AWOL and BR025 Rival, each with their own two-tone and lip treatments. Prefer to shop by color? Jump to black, bronze, blue, silver or gray options.
Fitment Coverage
Within 6x139.7, sizing runs from 16- and 17-inch up through 18- and 20-inch, suiting everything from compact trucks to full-size pickups and SUVs that share this six-lug spec. If you're cross-shopping bolt patterns, many of these same models also appear in 6x135 and 6x114.3, and the brand's car-oriented designs run in patterns like 5x114.3, 5x127 and 5x120. To narrow by size, see 17-inch, 18-inch and 20-inch fitments. Always confirm offset and width against your specific year and trim before ordering.
How to Choose
Start with the look: split-spoke and beadlock-style faces like the BR021 Mondo in Matte Gunmetal w/ Gloss Gray Lip read aggressive, while cleaner designs such as the 030 in Gloss Black keep things understated. Pick a diameter that leaves room for the tire you want, then match offset to your fender clearance and any lift. Daily drivers often favor matte and gloss black like the 200 in Matte Black or BR024 AWOL in Matte Black, while two-tone bronze and gunmetal builds like the BR025 Rival stand out on overland rigs. Every order ships free, and financing is available through Affirm.
