I have 315/70/17 BFG Ko2's I would like to mount and would like to know if the stock JL lug nuts fit these wheels? Also where will the inside wall of my new tires be in comparison with the old 285/70's?

  • The JL stock lug nuts will work with these wheels. On the Mammoth Boulder Beadlock Style Black Wheel - 16x8 (07-17 Wrangler JK) the Backspacing is 4.5" (114mm) and the Offset is 0mm (0") the 17 inch wheel has a Backspacing of 4.7" (121mm) and Offset of -6mm (-0.2"), therefore the inside wall of the new tires and wheel set up will be close to factory location.

    Great wheels and they fit DynaTrac ProGrip Brakes

    I've had a set of 17 inch Mammoth Boulder Black wheels on my 2017 JKU for 12 months and they're fantastic. Even better, I can confirm fitment with DynaTrac's ProGrip brake system. Even with tape weights, there is enough clearance for everything work work perfectly.

    Very nice

    These wheels shipped very fast and the packaging was in good condition. They look every better in person and look like good, quality, cast wheels. There aren’t many options for 16” wheels but these are perfect. I plan on putting them on Cooper St maxx
