Yes it was/is called the chevron pattern, good post for someone like me, I have been running them in a 16 inch by 750 size on my M38 for 20 years, they kick alot of but thru alot of mub bogs in there day, Directional tires are simply the best for traction in one direction, no tire has more, in a single direction, There are over the road directionals that come close to a tractor tire like U and I call it, used alot on stake body and dump trucks in the 1 ton range in the 60's and 70's , they are hard to find now, most tire places say they are not made anymore, but yes they are, U just need a real tire shop, I ran those on my cj2a's for all my life since i was 19, and they are only out done by the real tractor tire. The speeds are fine for the speeds our trucks should run, but they wear fast, obviously , the closest thing to them today and probably better because they are super off road and can handle the roads well also are the michelins the 1100's are the tire to get, U will find in my opnion that unless u are doing straight mud bogs the michelins are far superior to them simply because they are good for a wider variety and still retain the awesome one job rule , off road traction, a truck with the tractor tires we are drooling over here should really be trailered, but like everything else, any thing is only as dangerous as the driver makes it, and a novis will eat those up and probably crash too, my 3 cents, I love tires and have had more types on trucks and jeeps than most, sorry thats true. now just running them in the back like the 1 ton dump and rack body trucks did in the 60's and 70's would make more sense, and I would do it in a heart beat. and now u got me thinking, I am hoping to afford 3 air lockers in my deuce some day, that would be worth it, to use tractor tires not only for the traction but the "HOLY #$$%^^&& LOOK AT THAT TRUCK" thing, but I would also trailer it then, behind my five ton , Oh I should ad that my M38 has a 255 buick V6 and duel exhaust with 155 horsy's.not alot for some guys, but she is dangerous when U nail second,I hit second fast at the begining of a bog and by then i was at the end of the bog.they really cut the mud,
