Im trying to decide what to buy.. But some info first:

98XJ and it's not my DD anymore but I still like to drive it on the road and will continue to do that some. I drive it to and from the trails for now. Specs are 44's Ft/Rr, 5.13's, ARB and Aussie....

Tires im looking at:

36x13.5x15 Irok Bias (OD = 36.8, 64lbs) $186.00
36x13.5x15 Irok Radials (OD = 36, 81lbs) $230.00
37x12.5x15 MTR's (OD = 36.7, 76lbs) $243.00

I plan to run a 15x8, most likely a beadlock...

Please share your opinions on these tires... life expectancy, more accurate physical information (weight, OD, etc.), actual experiences...

Thanks,
Chris
 
I've run those Irok Radials for two years now...

just busted #4 and #5...thank goodness for 4WP warranty...

switching to the Bias this go 'round...but mine now lives on a trailer for the trips to/from the trail...

I like my setup with 15x8 and Stauns...:D

I run the 37" mtr with MRT beadlocks on and off road. They are a good dual purpose tire. I like driving around town a lot too in the warm seasons. Mine have been grooved for extra traction when off road and hook up great!

I'd say if it were off road only get the bias Irok because nothing beats the traction. Not sure if they would wear out on you too fast if you drive your rig to the trails since I don't have them. But have heard that they wear fast on the streets.

here's my mtr's...

i say bias irok but the highway will eat them up. price you pay for soft sticky offroad tires
 
Bias IROKs Best Offroad
Radial IROKs would be next with the MTRs a distant 3rd among your 3 choices.

The bias tires will wear quicker and hum more.

But they are much more puncture resistant, and grip is no comparison.
 
I would say get a cheap set of stealies and run the 36 16.5r humvee tires cause you can get them for cheap. But i heard the bias wear reall funny on the roads. My buddy ran 36 bias on his silverado and they started to warp? which made his truck wobbley so he went radial.
 
tire opinions are like asking if you like ford or chevy, with that said. i would stay away from the mtr's they don't like wet trerain. swapers are best for traction. but for road and off, pro-comps are best all around and they still go really good..
 
Used stuff is always the way to go for me. I got my beadlocks and tires already mounted up ready to bolt on for a whole lot less than new! about 8hundo or so...:beer:
 
Im going to give the Radial Iroks a try...

Greg,
just curious but how do you keep busting them..

Also, another question. The 36" Bias weight in around 65 lbs. while the Radials are around 80lbs. I know the weight is from the steel in them, and it seems like the bias tire would have a weaker sidewall? please explain this...

I went with bias ply iroks and ar767s w/bobbylong beadlocks. They are better than i thought they would be on the road. Mine are smooth up to about 70, unbalanced by the way. I think the beadlocked steel wheels help. Had to put the build on hold and they are currently in storage.
 
IROK comparison

The BIAS is taller, narrower, more flexible, and more round.
The RADIAL has a wide flat footprint that is stiffer across the tread
Here are the two IROKs side by side (Radial on left 15x10 at 25lbs. BIAS on right 15x9.25 beadlock at 15lbs:

The radial drives A LOT better than the BIAS on the street and lasts a lot longer.
The BIAS does a lot better off road than the radial although not really comparing apples to apples since I added beadlocks at the same time too. We'll have to wait for BigWaylon to switch.
 
I have the 36x13.5x15 IROKs on my K5, and I absolutely love them. As far as stickiness goes, they are awesome. I too drive to the trails.. but probably not for much longer. Mine probably have 500 miles on them or so... they have showed a tiny bit of wear, but not that much. If you aren't doing much street driving overall, I'd say go for the bias IROKs.

Click to expand...


all types of ways...some that would've ripped any tire I had...some because I ran too low of a tire pressure and they folded over and were cut...some just freakish accidents I can't explain...(and I'll admit one happened in the parking lot...but that's a different story)...
