I am wondering why more people dont use these on their trucks

What are they? Kerry

look like an agricultue field tire or overinflatted quad tires:smokin: :smokin:

They are agricultural tires.

I found this on the Izook board.

The problem that I see with them is that they have a very short sidewall. I think even my TSL's would flex better than those will.

I agree, those things won't flex well at all. I guess it depends what terrain you are running on, but I think those things would be terrible for rock-crawling. IMHO. ~Steve

a few years RRO was selling some ,they looked more like the typical tractor tread......$1200 a set ....most have been good, more Glenn hype.....:rolleyes:

the tires in the picture aren't really tractor tires.....that looks like the same tread pattern as the old goodyear xt's.....they used to market them for sand and mud.....they are actually pretty soft....i would think that they would be more likely to pinch a side wall than to not flex.....i looked into denman ditch diggers when i got my boggers....but i wasn't sure whether i could get a 31x15.5 onto a 10" rim.....:eek:

They are Good year super terra's. They work good in the sand, they aren't as stiff as they look, and I think they only come in 31"x 15" (I'm not positive on that one). Most of them are not DOT approved, but the ones I've got, are.

i think he runs them on beadlocks also. the guy is from alaska or canada. i cant remember. i know he claims they work very well at zero PSI in the snow with the beadlocks.

Well, Since they are mine I thought I would post some replies. First, those with the bandwidth go to http://home.gci.net/~ddesigns/zuki and click on the two links at the top - I posted a second page since the first pic was taken, and you can see some nice tire flex there. These might not be good for rocks - I don't have any to wheel on in Alaska. I do have stumps and roots to worry about. Mostly, these are to be trailered and swapped out at the trail head for really bad mud or snow runs.These are DOT but only to 30mph, not a good tire for the daily driver. I did try few runs up to 50mph, they were not nice. They make Boggers look like a good commuter tire. And at 31" they are a bit small. Oh, and they aren't bead locks but bead screws, through the inner and outer bead of the rim. Kind of crazy, but they work.

Pure Evil from the off-road bbs now has Bobcat tires on his Zuki.He told me after a trail ride that they were awsome in a straight line but in a camber situation,they want to slide.I think he paid 60.00 new.:usa:

hey! the rare Alaskan snow newbie! they're endangered, i hear.

Here, I pirated a pic off of his page. Should settle the flex questions. He mentions using bead screws, so I bet this is at 0-2 PSI:

heheheh you said pirated heheheheh:D

You need to post both pics, one with the stump hidden inside the tire first, then after I drove down the other side. I should mention also they take a LOT of torque to roll at zero psi ( I just screw on the the deflators and take 'em off when they are done). I have stock gears, but added a 1.9VWturbo diesel, and before these tires I didn't need to touch the throttle or feather the clutch to get rolling. Now I have to at least feather the clutch a little. It feels kind of like the e-brake is on, and holding real good, too. Then it gets rolling and it's fine, at least with the diesel. I think with the old 1.3 it just couldn't function with stock gears and these tires deflated. Power steering would be nice too, at least for the tight stuff. Also, my rear locker makes turning difficult, the rear kind of steers me straight in deeper(foot or more) snow, responding slowly to the turning input of the the front tires.

Side-slope slipping - I don't think so, not with these. Note the linear zig-zag down the center of the tire. I ran into side slope problems with my Mud Terrains at 2-3 psi in snow.....the tires rolled and I was on the smooth sidewalls. Not good for sidehills in snow. Still floated ok on the snowmachine trails. I haven't yet tried the Terra Traks. I haven't had time. My plan is to make a run to the Knik Glacier - in the summer this is an all day run, so we'll see. I have a friend with an 8x8 Argo to get me home if I get really stuck, and to bring help the next day ;>).

Do they work well in mud and snow? I wouldnt think a directional tire would.

Did you look at these things on my site? (link at the top of this thread)In the snow? In a foot of snow, I compressed it to about 4 inches, and never spun a tire. Kind of hard to steer (rear locker)but gripped like I was pouring glue on the ground. I just got them, so no mud yet, but they are tractor tires, man. They are more aggressive than Boggers(also directional), so heck, how could they not be awesome in mud? Here, take a peek at an Alaskan 4x4 site or two. MUD, MUD, MUD, we got mud. Or deep water, gravel, and mud.

hehe check out the swamp buggy with 42" tractor tires stuck in the silt. Too much weight, I'm thinking.

Ok this is going back eight years but I ran the same tire on my old Toy. They worked great in the mud and snow, the only down side was their height. Used them on the street as well, good for around town and that's about all. As for a directional tire being bad for mud, ahhh have you seen a bogger lately

Now that's some good muddin'. Wouldn't it be nice if these came in a 35x17.5? How was sidehilling? I would think they are gonna' be great, but you had some time to try them out, let me know how ya' liked them.

I never had any real problems with them offroad. They didn't last very long and for the price of them I probably wouldn't buy them again........OK, maybe if they came in 35's ;) Oh ya, the flotation in the snow at around 2psi is awsome!!!! I have a buddy that runs 46" field and turfs on his 502ci, 4wheel independant cruiser, they work great too with some minor tread carving.
