    I have a 91 yj Sahara with a stock front end that has a 4 inch lift. Will I need to modify it to accept 33x12.5's (Hub Spacers) for turning radius clearances?

    • Hello, the Mammoth Boulder Beadlock Style Charcoal Wheel - 15x8 Wheel - and Mickey Thompson Baja MTZ 33X12.50R15 (87-06 Wrangler YJ & TJ) offers a Backspacing: 3.7" (95mm) and an Offset: -19mm (-0.7") that setup should be good to install and be able to drive without having any rubbing on the turning radius, but we always advise our customers to install the wheels and check to see for clearance. Then get wheel spacers if necessary.

      Great looking wheels

      I wanted a wheel that was not black, no polished or chrome, and these fit the bill perfectly. They also are not the gaudy looking wheels so many Jeeps run these days, especially on JK's. These are near perfect. They set the Jeep off just right, not flashy, but not the over played black either. I waffled back and forth over these or the ones without the fake bead lock. In the end I choose the bead lock style, and don't regret it.

      Very Happy

      I've had these on my 2004 LJ for about 4 months and I'm very pleased with them. They look great and the finish has held up well so far. I've been hitting moderate/rocky trails weekly since putting them on and have zero scratches in the finish so far. The charcoal color is a very close match to my new Trektop NX. That's why I went with the charcoal color over black and I'm really happy with the decision.

      Great look, paint isn’t durable though

      Great looking wheel, I paired it with 33” tires. The only drawback I have found is that it’s described as an off-road wheel, yet mine have pealed paint just from the mounting and balancing process. When balanced, the machine pressed the front of the hub with a rubber press, and the rim around the hub shows white now vs the painted charcoal. So the wheel looks great initially, but would be better with a more durable paint, or powder coating.

      Perfect fit can form and finish.

      I was concerned about the off set/back spacing of the wheel when shopping for new wheels. These are a perfect fit for mounting 33-12.50-15.

      Mammoth Beadlocks

      Good looking wheels! Paired with 32x11.5x15 tires on a stock jeep. No issues.. They stick out 3 inches past the stock fender flares giving more clearance on the inside... No rubbing.. took forever to receive them, but i was compensated for it. Good product!!
