Brought new life to my Jeep. The wheels are sharp and well constructed. I matched them with Cooper MTP 31in tires. Stock with no lift and no tire rub.....

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?

Doug

  • 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.

Does the clear coat hold up to road salt I live in Wisconsin and don't want them to peel

Lewis

  • The Mammoth Boulder Beadlock Style Charcoal Wheel - 15x8 (87-06 Wrangler YJ & TJ) features a Charcoal Powder Coat Finish which is one of the most durable finishes available and should be very resistant to wear, chipping and peeling.

    Nice looking but

    I like the bead lock look of these rims and the color, my only complaint is that the paint did not cover all the way down into the lug nut hole area, it's like they sprayed them directly from the top and did not try to get paint down into the sides of the lug nut area. Otherwise they look great.

    Looks like the Pintler and half the price!

    Great looking wheels. Just like the discontinued AEV Pintler at half the price. The arrived fast and were packaged very well with several layers of protection. Finding the right wheels was easy because they are made just for Jeeps, not like other brands that have 15 variations and require hub center rings to make them fit right.

    New Mammoth Boulder Beadlocks Wheels

    Just got my new wheels installed along with new tires and the look great on my 97 TJ. I went from 31x10.50's to 33x12.50's and was concerned about the bigger tires rubbing, but the new Mammoth wheels have the perfect backspacing and do not rub at all when fully turned. The finish and quality of the wheels are great, the beadlocks style looks awesome, and you can't beat the great price with free shipping. Highly recommend! Thanks ET.

    Review from Mammoth Boulder Beadlock Style Charcoal Wheel - 15x8 Wheel - and Mudclaw Radial 31X10.50R15LT (87-06 Wrangler YJ & TJ)

    nice wheels and rims

    Made our 16 year old 2001 yellow TJ look almost new. The ride is smoother on the road than I expected and believe it or not less noise than the old goodyear tires. It gives a lower more mellow sound. They look great and got my first complement from a complete stranger about how nice they look....

    Fantastic!

    These wheels and tires look really great in person, absolutely fantastic deal for the money, tires are not noisy at all, handle quite well on a lifted Wrangler, and dig like a woodchuck in the mud! Highly recommend them, and the shipping was so fast, don't buy cheap black wheels when for the same money you can have these excellent wheels!

    Awesome wheel

    I purchased these wheels for my 92 YJ with 33 x 10.50 BFG mud tires. They look and ride great. I would caution you to trust their balance work though. I am. Dry happy with the finished product. The price is well below anything else around.

    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!!

    Great thus far.

    I am very pleased with the wheels. I was looking for hubcentric wheels for the Jeep that were a combination of stylish and affordable. These fit the bill well. The grey colored ones accent my Jeep's silver paint well.

    Great for the money

    Installed these on a 2000 Jeep TJ. Due to shipping one wheel came with a ding on the stainless lip. ET customer service made it right and I'm a happy camper. These look great especially with the yellow centers. Be careful with the powder coat, I think it's a little thin.

    Great looking wheels

    Quality seems very good. Like others have mentioned it would of been nice if the powdercoat went deeper in the stud holes. It's different looking because of its color, but that's what sets these wheels apart from others. So far we are happy with them and hope they hold up. They arrived VERY quickly and boxes were in new condition, which let me know they were handle well throughout the shipping process. This was my first time buying from Extremeterrain and I'm very happy with them.
