ok, atlas was founded in 1990, so that may be I was wrong, and armstrong has been bought out by Pierrli and it is kind of hard to find company info , but I am looking

No problem. I'm not "calling you" on it. Just hadn't heard about the "z" pattern stuff you mentioned.

I just went through patents for the early 80s, not in there
anyway the major development was the Z type of design, it gives maximum surface bite. It is recognized as a major design influence.
Funny, I found a 1984 patent by Goodwrench, for multi lug accross the pattern design. was killer trying to read all the legal terms trying to figure it out. but it looks like you can patent for lug count. wow.
I have seen 4 bangers break d 60s, If you want to go tit for tat we could argue for hours. what I was saying is it can be humbling to watch different rigs, and what is popular in the magizines can get a inexperienced guy in trouble fast.
Dorans entrance last year, watch 2 guys in rigs, almost brand new, with every bell and whistle on them, come up to the entrance and comense to destroy the rigs, and these rigs looked like they had just gotten out of the 4 wheel drive hardware garage with a unlimited budget. Carnage done, well last I saw they were on cell phones calling down to San Diego looking for a trailer to tow them each as both would not move. Dorans 2, built rigs with no clue 0. And talking to the guys they had full confidence they had built the rigs to conquer the entrance. Both were new to wheeling. Funny thing, a YJ with 2 inches of lift and a 4 popper went right on up before them. No Carnage. Having been doing this since high school in the 70s, I get told all the time my equiptment is to small, axles to weak,tires to small. But somehow I seem to be asked to lead a lot of runs, and asked what lines to take. I cannot figure it out, these guys have bigger badder rigs than mine.
as of right now, my jeep has a 6" spring under it, 35"s, CV shafts, SYE, no bars in it, and lock rights with stock axles, 4:1, and 4.56's, with the 2.5. no breakage as of right now. i watch guys with way more built rigs not get up half of what i do. and a lot of them break stuff in trying to do stuff. i just take my time and pick my line carefully, and i dont break stuff.
but i still dont understand what you are getting at. this doesnt relate to the skiiny or fat tires, just getting the power to the ground.
i was jsut browsing a totally non scientific article and here is an excerpt that i think is wildly amusing
The point is larger off-road tires are meant first and foremost for the purpose of raising the height and ground clearance of your rig to enable steeper ascent and descent in off-road terrain. Simply put, when driving over boulders, slogging through mud, coasting across the desert, or even just making your way through the occasional forest trail, higher ground clearance facilitates negotiating certain obstacles.
Not to downplay the traction aspect of off road tires, as a set of mud terrain bias off road tires will most definitely perform better in the mud than a set of all-season radials. Rather, improved traction is more of a secondary function that still bears importance, but should not the sole consideration when it comes to buying truck tires, as there are far better truck parts available for meeting that goal.
duh we all know this... duh we all fail to apply this knowledge and end up hyperfocusing on traction and friction etc. for me and my FJ i think a 10" tire and perhaps a 10.5 would be ideal especially considering overall rotational mass (especially when considering driveline stress) and overall dimensions. a 5.5" backspacing on a 10" wide tire will yield a slightly larger trac than stock without substantially increasing the overall vehicle width and diminishing my fitability (you like that word? i do!) of course it all boils down to personal preference and driving style, but it really turned a lightbulb on for me to remember that the primary thing tires do is lift, there are many many other things that focus on making the tires go.
PHYSICS!?!? what the heck does physics have to do with 4 wheeling!?! i mean come on! how many physicists do you see winning off road competitions? i dont think Einstein ran Krawlers. off-roading is about magic, not physics!
(of course i may have to re think that because i dont think Harry Potter ran Krawlers either)
(if you didnt laugh you missed the point )
also i just thought of somthing else i dont think i saw considered here: overall diameter is really more important than width. i mean 30-inch tire meets t30-inch rock (any rock i dont care pick one as long as its 30-inches) tires lose unless backedup by sufficent components (gearing, lockers engine torque etc) same rock but with 40-inch tires, reduces the need for these helper components because of where the obstacle is met by the tire on its curve. thats why 46" tires take all the fun out of wheeling, there jsut arent many obstacles for that. of course mud and sand and snow are slightly different but... meh...
My first car ( Ok dating myself) was a '46 ford coupe. flathead V8. with the 6.00 x 16 inch tires...and would it go thru mud & snow. Pulled many a truck out of ditches and muddy roads. Course the mud wasn't that deep, just greasy. so those little tires just cut thru.

I guess you never will, so why should I bother with you?
