I'm a BIG FAN of the Nitto mud Grapplers too.

Not as loud as most aggressive off road tires...more a "HUMMMM"...
...than the "WOMP WOMP WOMP" from others.

And yes indeeeediee...they last very well.

Limited sizes may be the issue...
...they messed me up by stopping the 33x12:50x16...and if YOU want 16's then Nitto Mud Grapplers are not available in that size.
However IIRC...they do have 33x12:50 x 17 or 18

So instead I found a used set of Nitto 35x16's...and love 'em.

I will be buying new Nitto 35's after Moab this year....
....they rock in the "looks" and "works" departments
