Black Rock is a registered trademark of Titan International and builds many classic off-road styles with offsets, backspacings, and bolt patterns aimed squarely at truck, Jeep, 4x4, and off-road vehicles. That heritage shows in the 6x5.50 fitments here, where the focus is durability and a timeless silhouette rather than flash. You can browse the full Black Rock lineup to see how this bolt pattern fits into the wider range.
Why 6x5.50 Black Rock wheels matter
The 6x5.50 pattern is one of the most common six-lug layouts on the road, covering a huge swath of half-ton trucks and full-size SUVs. Choosing a wheel built for honest off-road use means you get the kind of simple, strong design Black Rock is known for. The Matte Black finish keeps brake dust and trail grime from standing out, and it pairs naturally with both stock and lifted setups. If you want to compare darker styling across the whole brand, the black Black Rock wheels collection rounds up every dark-finish option.
Which models & finishes are offered
Three Black Rock models carry the 6x5.50 bolt pattern: the 929B Blackjack, the 942B Black D-Window, and the 997B Soft 8. All three are offered in Matte Black, and each is a monoblock design.
The 997B Soft 8 is the broadest of the three, available across 15, 16, and 17-inch diameters and the widest spread of bolt patterns. A representative example is the 997B Soft 8 17x8 +00 Matte Black. The Blackjack runs in 15 and 16 inch — see the 929B Blackjack 15x10 -38 Matte Black for an aggressive fitment — while the D-Window adds a 17-inch option alongside its smaller sizes, like the 942B Black D-Window 16x7 Matte Black.
Fitment coverage
Across the 6x5.50 group you'll find 15, 16, and 17-inch diameters. The models here also span related patterns including 5x4.50, 5x4.75, 5x5.00, 5x5.50, and the eight-lug 8x6.50 layout, so a single design can suit very different platforms. To shop strictly by size, the 15" Black Rock wheels, 16" Black Rock wheels, and 17" Black Rock wheels pages narrow things down quickly. Always confirm the exact diameter, width, and offset match your truck or SUV before ordering.
How to choose
Start with your bolt pattern — confirm it's truly 6x5.50 — then pick a diameter that suits your tire plan. If you want maximum size flexibility, the 997B Soft 8 covers the most ground. For a deeper, more aggressive fitment, the Blackjack offers wider, lower-offset options. The D-Window splits the difference with a clean spoke design through 17 inches. Every order ships free, and financing is available through Affirm to spread the cost across a full set.
