        I would like to run 33" by 12.5" tires. can I do this with 16" rims? Is there any benefit between 16 / 17 with the same total height. (I like the look of smaller rim w/larger tire)

        • If your looking to run a 33x12.5R16 you would want to run a 305/70R16 tire. The benefit for running a larger tire is when airing them down for heavy off roading, and it can provide a softer ride feel on roads.

        the rims on my 2017 jeep wrangler are 16 x7 if i change rims to 16x8 will i need new tires

        • You can visit the tire manufacturer's website to check what wheel size is appropriate for the tires you currently have.

            Sarp Wheels

            2015 Wrangler JK 16" x 8" wheels with 265/70/16 Cooper AT3 These Boulder wheels in satin black are just super sharp. Not too much, not too little. They made a huge difference on my Jeep. I'll up grade the tires to 33's later, but even these 31's have a great look to them mow.

            Great tires and wheels (pre-assembly was iffy)

            Wheels and tires were great but two of five stems were loose and leaking. I would recommend having the local shop look everything over before mounting them.

            Love them

            My Jeep now has the stance it’s always wanted. Shipped without hastle although one wheel came a day later. A call to ExtremeTerrain alienated all anxiety about the delay. Found the staff at ExtremeTerrain we’re very helpful and figured out all the offset issues.

            Wheels look “sick”

            Since putting on the 16” wheel with 315 Nitto Trail grapplers I get lots of good comments. Recently ran Drummond Island, MI and the combination tire to wheel performed fantastically.

            Excellent wheels. I’ve bought the “big brand names” in the past and these Mammoth’s live up to any other. Plus you cannot beat the price, all 4 under 500. It’s like a bogo. They look great on too!! As long as I have my Jeep these wheels will be on it.

            Great wheels

            These wheels look great ! The guy at the tire shop was really impressed with the new look of my JK. The wife was a little unsure of the style (she prefers shiny polished wheels) but when she saw them on the Jeep she said it looked tough.

            New Wheels, New Feel

            Bought the Wrangler with after market wheels, Plastic Caps for centers, made a rattle on bumps that made me grit my teeth. New wheels look great and I am not gritting my theeth on Bumpy roads. Should have purchased these Mammoth Wheels sooner.
