I dont really agree regarding "Mud" tires being bad for Moab.
I have consistently run Nitto Mud Grapplers at Moab ...
....and also driven other VX's there, with other brands.
I swear by my Mud Grapplers.....and just purchased a new set.
(They last very well... 5 years , and are not super noisy on normal roads)
When aired down correctly ( one of my issues on Hells Gate!)...
...I have found them excellent.
And...the big bonus is a very meaty/chunky side wall that offers all
kinds of additional traction and side wall protection.
