irok tires?

[jeeping1974]

So i was looking into tires for my jeep. i have a set of 16.5x10 wheels that are getting a bead lock kit. i've got plenty of room for a 36"-37" tire even at full flex. i am looking into a set of irok bias-ply tires. i figured since so many people here and some of the more hardcore guys around my area have all had great luck with them then i should go with them also.

the first size is 36x13.50-16.5LT. they measure out to 36.8" tall. the second size is 37x14.00-16.5LT and measure 36.36" tall. (got the sizes from interco's website. there is only a $10 difference and a .5" width difference. the 36 can handle 11o pounds more than the 37 and is about 1.5" wider tread width. i'm just not sure which one that i should go with. i am thinking about going with the 36x13.50-16.5LT. what do you guys think? am i thinking too much and it doesn't really matter or is there something that i'm missing? thanks for any and all input.

i know that someone is going to say "its your jeep, use whichever one you want". i'm just looking for input really so that i can make the proper choice.

less than an inch difference in height and when you put the beadlock kit on it'll spread the tire out that extra inch. save $10/tire and call it good.

i like mine :thumbsup:

im running 42x14x16.5 and i love them. i would keep them but im gonna go to an ltb for my next tire. (once my 42's get worn out).

i agree w/ OC. but then again w/ the 37's, you would be able to say that you have 37's. not weenie 36's. :D

[Sambo]

save $40 :thumbsup:

Like Pontiac's slogin used to be.
Wider is better!

Have you looked up what people are really measuring the height of these tires at?
Just because Interco lists them as that height, that doesn't mean they WILL be that height.
And are those tire heights they spec out on a 10" rim?

[Stuka]

The actual height of a 36x13.50 is 36.8" tall on a 9.75" wide wheel.

The actual height of a 37x14.00 is 36.36" tall on a 11" wide wheel.

Specs are per Interco's web site. However, I think they may have got them backwards. As they claim the 36 is over an inch wider than the 37, which just isnt right...

But... I say go for the 37 :)

[Hammer]

Some comments I found on Pirate were that the 36" tire was fairly rounded, where as the 37" tire, while being a little shorter, has a more squared off look.
I never liked the round bulging tire look, so the 37" is DEFINITELY my vote.

I hate the inner tube look... I voted for the 37"s... Bigger is better!




(Well, to an extent at least.. :huh:)

[Desert Beast]

the list my 42's @ 41.5" od. mine only measured 40" brand new. so those sizes are a bit inflated.

the 36 is based on a 16.5x9.75 and the 37 is based on a 16.5x11. like Stuka said, that was pulled off their website. also the 37s are $10 more but where i'm spending the money for a bead lock kit, $50 doesn't really concern me that much, just have to explain it to the little lady why it was so important. haha

[orangecherokee]

Round vs. square....

uh yeah, so anyway when you deflate the tires out it won't matter. I think I'd be more concerned with performance. Put the $50 towards the beadlocks and save a few.

[trail mule]

I say go for the 37's.

Actually, is does matter when you deflate them.
At least it has for the ones I have used and seen.
The round ones deflated to 8-10 psi get messy with the tread blocks rolling too much.
The square ones (we are not talking about BFG or other want to be off road tires), you can get the same contract patch and similair, if not better control over the sidewalls, with more air, like around 14-16 psi.

Those are from the different swampers I have used. I can't say this will absolutely be the case of these Iroks though.

As for tire height, I think there are very few of them that are spot on with what they list.
The 39.5" TSL is supposed to be spot on for height.
Heck, Dmntx77 has 38.5x14.50x16.5" TSL SX and they measure almost true (he does have a narrow rim though).
I have 38.5x14.50x15" TSL SX and they don't even measure 36.5". I am using 10" rims when it calls for 12", so I am cheating and they are STILL short!

i've seen both on an Irok and my statement stands.

[Dmntxn77]

Well, if they are wider inflated then they will also be wider deflated... Wider means larger contact patch.. Larger contact patch means better traction.. :huh:


At the moment with 4wheelparts offering 10% off and free shipping, I personally would go with SX's.. The price for the same tires I have will be under a grand, which is about the same as the smaller Irocs at regular price.. Personally, I think SX's are a better option..

[Hammer]

Ah well, you got me there, cause I haven't played with the Iroks myself.
I still vote for the 37" though, wider tread, better look, etc.
And with if they are aired up for driving on the road, they should make a difference in handling and tire wear (not a part of the OP's question though).

Im running the ltb's myself.. Just wondered why the switch to them?

[blt2krl]

I would run the 36's. Your going to lose height with either size due to you adding on the beadlock kits. People usually trie and run a smaller rim to help keep tires on the beads but it also causes the sidewall to not buldge as much which in turn gives the max potential tire height. Either where there is not a significant height advantage when you get the tires mounted on the beadlocks. I would step up to 39.5's. In fact I will sell you mine, I need some 42's:D

b/c the irok doesnt come in a 47" size. :D (and i think that the 49" irok is too wide for my liking.)

i would love to run 39.5s, heck even 38.5s but i've already cut my fenders and don't have the room for a tire that large. plus i only have a HDD44 front, i'm sure the FFD60 rear would be able to handle it though. i am figuring that the 36 and 37 will measure out to about a 35" - 35.5" tire. (the 33s i was running barely hit 31") plus the 39.5 wieght in about 20 pounds heavier tha the 36s, couple that with a steel wheel and bead locks and you looking at one unmotivated person to move them. haha

i have only seen one guy around in my area run SXs. he said they were fine and do grab really well but just wished that they made a wider 36" tire. i feel the same way. i have always run narrow tires and want something wider (13"-14" range).

[jeeping1974]

hahaha

i'm pretty sure that i am gonna go with the 36x13.5. my D44 will be happier and i can still run some of the more fun trails (just have to pick the right line).

thanks for all the info guys!

[landbruiser1]

I would say the 36's. When I bought my 37 MTR's a few years back I couldnt find a spare for a 37 anywhere, not really as a common tire as a 36..

I now run the 39.5 Iroks and love them. great tire, but will wear quickly on the street.

[jeeping1974]

well the tires will never see pavement so i should be all set there.

[Stuka]

37" MTR's were rare because the military was buying all of them. This is not so with Interco.

Also, a spare is needed more offroad than it is onroad IMHO. I have gotten two flats within seconds of each other on a trail ride before. Getting one flat is pretty common. Although less common with bias ply tires.

[Hammer]

Yeah, but carrying spare tires in this range starts to become a serious issue on SPACE! I know the 38" tires of mine take a LOT of space up!

[jeeping1974]

thats why i've got a long bed. it helps out a lot with carring a larger size tire and still have space for tools and a cooler.

[COLOFIREMAN]

I run the 39X13.50X15 a 15x12 rim on my 84' CJ7 and I love these tires above any that I have used in the past. Snow, Mud, Sand, Ice, They work the best on all surfaces. The only problem with them is because they work so good off road, they tend to wear quickly on road.:thumbsup:

[AlsChopShop]

i keep hearing they will wear really fast on the street... but how fast? like how many miles can i expect out of a set? i'm considering some iroks for my next tires, and while the jeep won't be my daily driver i will drive it to and from trails when i can and occasionally on weekends.

actually people are turning them around now. not everyone but once the edges start getting worn off the outer lugs some will turn them around for a fresh bite.

[-Bluegill-]

I sure do like mine! :thumbsup: But I can tell ya from experience, the 36x13.50's actual mounted height on my Cherk (at 13psi) is 35.7" tall with a 10" wide rim.

You said your J10 wouldn't see pavement, which is a good thing. I drive my Cherk to/from the trails (no tow rig :() and lemme tell ya, the bias IROKs do tend to "walk the dog" on me. Definitely takes some getting used to them. I run 13psi in them on the street, any more and the contact patch is pitiful. At 40mph you'll know that these aren't street friendly tires; at 55mph they remind me of wearing ear plugs and muffs while riding in a C130 airplane. BUT - they give almost magical traction off road, clean out super easy, and are tough as nails!

[Michael]

I have two runs on the 37x 14.00 actually are 36" tall. So far so good but only time will tell. They bite right now the best of any tire I have had so far.

[jeepboy69]

if you like mud then you want narrow. if you want all around widers better, like the boggers with groovs are great in the goo. but ive seen irocks rock in the goo. so go wide makes it look cool.

[-Bluegill-]

so go wide makes it look cool.

Wide meats make great "curb feelers" around really tight turns too. :thumbsup:
(rocks/trees/etc)

[Thumpszilla]

Go with the 36's the ones on -Bluegill- cherk came off my j-10 and I loved them but like he said you definately don't need much air in them. We put them on my waggy with 0psi and the didn't even sag. But I never even got the sidewalls broke in on them.

Which gears you have in the diff?

Which gears you have in the diff?

Back then I had 4.56 gears.

I've got 5.38 gears now and looking to go larger.
