Who run's Irok's here?

[Danimal]

Probably a lot of you. I want to hear some feedback (no assumptions of BFG fanboy's please :cwm30: ) about what I can expect and not expect from these tires.

I plan to move from 35"/12.5" MTRs to 37"/14" Iroks.

The truck is built for climbing and most likely won't see much mud in its lifetime unless you call BC's signature trail sludge (logs, half decomposed leaves, dirt) mud, so thats an idea of the vehicles purpose.

So what are these tires really good at from your experiences? What are they really bad at? Anything a new owner should know before jumping into them?

Thanks

[DaveW]

I've run quite a few different tires. BFG's, Swamper TSLs, MTR's, etc, etc.

For a trail tire in BC I would put the IROKs up against anything. The work well in the trail sludge you speak of, good on rocks, and good in the snow. The only drawback to these tires would be the wear and tear on the street, because they are soft. But my rig never really sees the street anymore so I don't worry about that.

I wanted a tire for similar reasons. The island trails which cause most of the grief for my Jeep feature wet or mud-covered rock, loam, and wet roots. I recently switched to 36" IROKs and the difference was incredible (used to run a variety of radial muds before that). Many of the island guys also like 'em.

Although the tires were new, I was able to air down to around 7 psi without any problem, and the sidewalls flexed quite well.

Like Dave, my Jeep is ONLY for offroading so I'm not worried about highway wear. They were pretty easy to balance, too. IIRC, the worst tire needed about 8 or 9 ounces of weights. Noise on the hwy isn't bad at all, either.

Ha, ha! Look at you guys: Island Irok converts;)

Well. Oddly i am agreing with the last two posters.... plus, I run them for nearly 2 years as a DD and still had about 55-60% left.
Sadly, I still have 55-60% left...

[Danimal]

Well thats absolutely great news!

I am doing another 2 phases of mods to my truck that will officially turn it into a trail buggy, so the only road it will see will be to the trail and maybe down to tim hortons on occasion for a treat and to get some odd smiles/frowns from the public :redneck

Really like the feedback thus far though, looks promising.

Has anyone ran the 14" wide Irok's? I haven't got much experience with a wide tire like that. Not sure what to expect.

I'll be running Hydro-assist steering with selectable lockers so turning shouldnt be a huge issue. Anything else I should be aware of?

[builtzuki]

I have the 39.5s irocs and love them

[rkjplt1]

What about Radial Irok's Vs. Bias Ply's?

[S.C. Offroad]

I run the 37x13.5 iroks on my 2500HD diesel and they are just for pavement and looks and they aren't to noisey and I have about 20000km on them and 50% tread remaining, balanced quite well, just make sure you rotate them quite often

[DaveW]

Bias better than radial

[Poopy]

I just picked up my 42's yesterday, man they look nice. Deep lugs, and a nice square profile, no balloon action.

[rkjplt1]

What did they change from the old 36.5 to the 37's? Just the sidewall #'s?

What's their OD? I don't trust the site specs...

[Poopy]

With no air or wheel they are about 40 5/8"

[buckle]

they look too baloony' for me, plus i hate the tread depth. theres ntothing there... its like buying a tire thats allready 50% worn...

after listening to stinkfinger talk about murdougs iroks, i canged my mind and didnt buy them.

I got 38 5 boggers instead and love them

[Poopy]

You havent seen the 42's i take it? SQUARE and DEEP TREAD. :cwm18:

[buckle]

when can i come take alook?

and check out the yard:D

[Poopy]

Heres a pic or 4:

Im going out now to pick up an excavator, but will be back in 2 hours if you wanna drop by.

[MudKick]

15s poopy?
I'm, thinking 17s next time around.

And buckle, I will be buying a next set of the same tire, just bigger.
This never hapened to me before, so if that's not a testiment to the tire I don't know what is...
Enjoy your tractor tires in the mean time. I hear they're good in mud...:poke:

[Poopy]

Those would be 16's :cwm30:

[Danimal]

Can't wait to start running these. They'll go good with my ARB lockers and about 18" bobb in 2 months :)

Thanks for the pics Poopy. looks sick

[buckle]

after seeing these tires today, i decided my next tires will be 42 inch iroks:D

BUT keeping that in mind, i still would notrun a 39.5 or 36 irok, because they are a totally different tire that these 42's

[lars]

Tread depth on the IROKs depends on the tire size. Like Poopy says, you definitely need to look at them before assuming they're all the same.

You best get a 60 then :poke:

Hmmm... Would tread depth be an issue with the 37" ? And is the OD accurate that is on their website? Anyone have a real-life measurement for the OD of a 37" Irok?

I wish Krawlers weren't so expensive :shakehead:

[buckle]

relax

ill have a 60 by the end of feburary i think:beer_cheers:

[michael]

I bought a set of widened Hummer rims that I plan to put 42 Irocs on
my only trepidation is that the guy I bought the rims from had 42 Irocs on them and changed to a different tire.

[Spike Jones]

I had 36" Bias Iroks on my Jeep (before I sold it) when they got to around 50% they were horible on the street.... Mind you they were 14" wide.

Overall I was not happy with them and would never buy them again. But thats just my 2 cents.

[MuddMachine]

According INTERCO (http://www.intercotire.com/site25.php) the 42's have 3/32 more tread then all the other Iroks. Except for the 49's, they are 28/32, just 1/8" more for all that tire.

:confused:

So aside from most people saying the bias are better than the radials, I'd like to know why from the people who have run both. I know the bias will obviously be tougher on the sidewalls but what else. My ongoing build has me torn on radials or bias. Reason being is that the radials are usually alot lighter. Which to me makes a big difference in my tire choice.

[MudKick]

I have not run a radial Irok, but I run a variety of other radial tires and imagine the "concept" of radial tire would also apply to radial Irok.
The difference I noticed that the radial tires, even aired down to absolute minimum, to the point of looking nearly flat, do not conform to "sharp" features in terrain as well as my bias Iroks do...
Driving on top of pointy rock with the radial tire you can see how the steel belts inside prevent the thread section of the tire from fully complying with the terrain. Oddly, even though the sidewalls on the radials i run were not even nearly as strong as the Irok, they did not provide any "torque" flex, or wrinkling as I call it. They seemed to follow the rim and tended to spin on obsticles.

The Irok bias on the other hand, as baloony as it seems provides a lot of contact patch when aired down with a pretty large foot print but without looking flat (side wall vertical strength I think...). When driving on a pointy object unlike radials it's not the sidewall that flexes but the thread astually hugs the terrain. Also looking at the tire/sidewall from the side I noticed a large amount of "wrinkling" when applying torque. It's as if the thread of the tire grabs the terrain and stays there while the rim and consequently the truck already starts climbing up, but the sidewall flexes and wrinkles around rim. It seems to really help in not braking traction in severe angle climbs where torque would easly brake the radials lose and cause spin out...

I don't know how scientific all of this sounds, but that's what i experienced/observed and concluded myself after 2 year use...

On the thread issue, I think the tire is using such a soft and compliant compound, which is what makes it works so well, that if there was a signifficantly larger amount of rubber there, there would be even more chunking... So, Interco siped the tire to kill two birds with one stone:
1. Even better traction due to better lug complience
2. Better heat transfer, saving the lugs from chunking if used on road a lot...

... my $.02...

Went out with Kraqa this weekend, he runs the 40 IROK's. Holy shmokes they kick ass!! Mud, rock, trees, anything, they worked really well. :beer_cheers:

They are actually 39.5's .

[Dan Martz]

ive had my Irocks for almost a year on my BJ60 wagon. Best tire i have ever owned. good on the road,mud, snow, and rock. My only dislike is that they are a little soft. I guess cruiser wagons are a little heavy at 6k+:cwm30:

[Danimal]

On my first rig (sprung over 88.5 Samurai) I ran 33" baja claws. They seemed to be a great tire from my limited experience with different tires. They grabbed great in wet trail muck and also mud. Didn't get a chance to test them out on dry rocks, but thats pretty unrealistic for BC anyways.

So now I'm not sure if I want to go with 37" Iroks or 38" Claws. Anyone want to chime in on this? I'm just looking for a tire thats going to let the rest of my truck work to its potential.

Cheers

[Poopy]

How many built trucks do you see running baja claws?

I know of alot, more than IROK's even. Of course they have different needs for thier vehicles than lower mainlanders.

Yes down here, nobody i wheel with runs them, and we are quite the elitist group.:confused2

Maybe they work well in the desert of kelowna, as their name implies. :redneck :redneck

I have never run them, maybe Danny can start a new trend!

Er.... It's snow that they seem to work better in. :shakehead:
Although I do know of one guy that has his eyes on some 49" IROKs.

[MudKick]

Claws suck here!

[EHeye]

My boss has 33" claws on his cruiser, they dont work to bad, but he doesn't have the wheel speed to clean them when they get mucky. Diesel. :beer_cheers:

[JIMMIE]

They are actually 39.5's .

and yours are 41.5's :poke:

[belmont mild]

Any plcases with 36X12.5 X15 iroks local brand new ? Anyone or is it all a wait to order them? Kind of want 4 plus a brand new spare as well!
