who's got 33''s by 12.5 on a nbs?

Like the title says who is running 33'' by 12.5 on a nbs? I got some new 18" with a 0 offset and 5" backspace and wondering if I can fit some 33" by 12.5 without rubbing everywhere. Gonna just level it out

I'm running 33x12.5x20 nitto terra grapplers on +12 offset on mine with the t-bars cranked and I did the small fender mod for no rubbing at all. here are a few shots.

Cool,thanks for the pictures also. I see you used to have the 275's,was that a big difference in fuel mileage going to the 12.5?

Hard to say because it was about 35 degrees warmer and I don't believe I was using winter blend fuel yet when I had the coopers on. With winter blend and about 20 degrees out its about 1 mpg drop

You need to be more specific than NBS... The new frame design on the LMLs allow for larger tires than the LMMs
