Terra Grapplers are wider, more aggressive and way noisier than Trail Grapplers. Toyo muds seem to be the holy grail of tires for our trucks but, they tend to be wider than labeled and heavy. The Mickey Thompsons I have been around have been good offroad but loud and fast wearing- disclaimer: I have only been around their aggressive treads, not their more all terrain oriented treads.
Truck and SUV tires I have owned over the years (I think this is all of them):
BFG all terrains (on my ZR2 Blazer and on my Power Wagon):
quiet with nice road manners. Okay on rocks (but chunk), crap in mud
BFG mud terrains KM1 and Rubicon specific KM2s (Blazer ZR2, lifted V-8 ZJ, and JKU Rubicon):
Fine on the street, a little lacking in traction in inclement weather on road though. KM1s were great in rocks and mud!!! (sunk in sand though) KM2s never got wheeled.
Dick Cepek mud terrains (on my Silverado Classic Duramax):
Loud and fast/choppy wearing on the street, did great the one time I hit mud
Cooper STT muds (87 GMC Jimmy on 'tons):
Okay on the street (quieter than the swampers before them) nice on rocks/mud
Some kind of Swamper radials (87 GMC Jimmy prior to going 'tons):
surprisingly quiet on the street for what I expected, never wheeled with em
Goodyear MTRKs (JKU Rubicon and Power Wagon)
Balanced okay on the JKUR (35s) but didn't balance for crap on the Wagon (37s) A bit loud on the street but great in rocks and mud! Did chunk bad enough to ruin one tire on the Power Wagon though, tore a tre out and split to the belts!
Goodyear Wrangler Duratracs (Silverado Classic Duramax):
Wore well, quiet, didn't get stuck the one time I hit mud. (thank goodness, it was foot deep trash mud at the demolition materials section of the landfill, that would have been a DISGUSTING recovery effort, LOL!)
Michelin LTX M&S (Chevy Silverado Classic Duramax):
Rode like heaven on the road, wore like iron, super ultra quiet. But, I never once would ever even try to wheel them! They did well on the road in snow but, I doubt they'd do well in the mud portion of M&S, LOL!
Nitto Trail Grapplers (current (as of about two weeks ago) tires on my Power Wagon) I LOVE them so far! They balanced pretty well, they ride nicely and aren't too loud. They fit better than the MTRKs (less rubbing) and thus I can turn a little sharper! They are heavy though(about 15lbs more a tire, IIRC), I can't light them up like I could the MTRKs, also I dropped 1mpg in comparison. I haven't had them in mud (I avoid it!) but, they did pretty well in the rocks this past weekend (nothing hardcore, just did the mid range trails since I don't have sliders anymore right now!), I've done about 1400 road miles so far and they have done well!
I can prove I have Nittos now too, LOL! brianh416, your pics were part of pushing me over to them!
With caps:
Without caps:
Without Nittos, LOL! (whilst Plastidipping the wheels):
And how they are now (except they're dirty now, this is the only clean pic i have, DOH!!!):
Anyways, sorry for the hijack, couldn't resist sharing some pics!!! bryanh416, that sure is a sharp looking truck you've got there sir!!!! (I could be partial to gray though, LOL!!!)
