Mammoth Boulder Simulated Beadlock Style Charcoal Wheel; 17x9: Immerse your vehicle in style and elegance with this wheel's captivating matte black finish. The unique 10-hole design of this Mammoth wheel sets your vehicle apart, making a statement on the road. Whether cruising the city streets or heading out for a weekend escape, this wheel complements a wide range of vehicle styles.

One-Piece Cast Wheel. This wheel is manufactured using gravity casting. Gravity casting is the process of pouring molten aluminum alloy into a wheel mold or form and utilizing the earth's own gravity to help fill the mold. The result is a strong, durable wheel that has the same good looks as a more expensive wheel, at a fraction of the price.
Application: This Mammoth Boulder Simulated Beadlock Style Charcoal Wheel; 17x9, with a backspace of nan and bolt pattern of 5 x 127mm (5 x 5-Inch), ensures driving stability and optimal alignment. Designed to fit 1999-2004 Jeep Grand Cherokee WJ, it is a perfect match for those seeking a blend of style and functionality. Sold individually.
Fitment:
Mounting & Balancing ExtremeTerrain offers professional mounting and balancing on all wheels and tires when purchased together on the same order. This will allow you to swap out your old wheels for your new set when they arrive.
What is TPMS? The Tire Pressure Monitoring System (TPMS for short) is a factory installed safety feature on all 2007 and newer Jeep Gladiator that alerts you when your tire pressure drops to an unsafe limit.
How do I keep my TPMS feature? Aftermarket wheels do not come with TPMS sensors. However, if you select 'Add TPMS Sensor’ and your specific year range from the options listed above, we'll install the TPMS Sensors in your new wheels!
For more Information, check out TPMS Sensor Kits in detail.

Great wheel, do not buy as part of the Black Friday sale. They’re up charging you. I’ve bought these before for $160 on extreme terrain. Photo for proof

Looks great!
I had these put on when I had my lift kit installed. For the lift, tires, and wheels it was great and took about 4 hours!

Great product BUT...
No issues with wheels and tires or shipping - arrived two days early and in perfect condition. BUT two issues with customer service. First, Jackie was a great help explaining products and recommendations. When I called next day to order, this clueless rep needed ME to set HIM straight. SECOND, since ordering, at least THREE TIMES A DAY, I have been receiving emails advertising - wait for it - WHEELS AND TIRES! I have unsubscribed, and will need to think twice before ordering again.

Used the in-store mount and balance with new valve stems, best choice yet.

Wheel and tire package
Love the look and function of the new wheels and tires. I did order the tpms monitors with the setup and am having difficulty consistently getting them to register.
