I have the Terra Grapplers (AT) on my Ford Superduty with almost 30,000 miles on them and still have a little more than half the tread left but they load up bad in the mud. I put the Trail Grapplers (MT) on the JK and love them ! They do weigh more than most but perform well and are not as loud as some other mudders.

 

I have these on my Suburban and my JK. I think they are great tires.
