About This Wheel

Pick up a Selkirk and the first thing you notice is how deliberate the spoke layout is — thick, blunt spokes with a slight taper that reads as heavy-duty rather than decorative. The face isn't trying to look busy. The milled pockets cut between spokes catch light differently depending on angle, giving you that two-tone contrast without a separate painted window. On white or silver trucks the dark face anchors the whole build. On black or charcoal rigs it blends into the body and lets the milled edges do the talking. It suits full-size Silverados, Sierras, Tundras, and 4Runners equally well — basically anything riding a 5x139.7 bolt circle that needs width and presence.

Fitment

This wheel runs the 5x139.7 bolt pattern, which covers a range of half-ton trucks and SUVs depending on hub bore and offset. ET-12mm offset is typical for stock-height fitments; leveled and lifted trucks may want different offset/backspacing combinations to clear larger tires. A hub-centric ring is recommended when the wheel hub bore is larger than the vehicle hub.

About the GLOSS BLACK MILLED Finish

Black Rhino Hard Alloys has been producing truck and SUV-specific fitments since the mid-2000s, focusing almost entirely on larger bolt patterns and aggressive offsets that the mainstream wheel brands tend to ignore. They're not a lifestyle brand chasing trends — their catalog is built around what actually fits lifted and leveled trucks, and the Selkirk is a straightforward example of that approach.

About Black Rhino Hard Alloys

Black Rhino Hard Alloys produces wheels distributed nationally through trusted vendor channels. Catalogs are stocked, MAP-pricing is enforced, and warranty coverage is honored at the manufacturer level.

Questions We Get

Will this fit my truck?

This wheel is spec'd at 20x10 with a -12mm offset on a 5x139.7 bolt circle, which covers many full-size GM trucks, Toyota Tundras, and 4Runners among others. That said, fitment depends on your specific year, trim, and any lift or leveling kit you're running, so confirm your hub bore and clearance before ordering.

Do lug nuts come included?

Lug nuts are not included with the wheel. Most aftermarket wheels require open-ended lug nuts to clear the lug seat properly, and the correct seat type — typically conical or mag — depends on your vehicle, so it's worth double-checking before you're sitting in the driveway missing hardware.
