so it's down to these 2 tires. 36x13.5 irok vs 38x12.5 tsl. These will see very little road. 80% rocks 10% road 10% mud whats the better tire?

also they will be going on my tj so if you have any pics of these post them up! i would also like to see if anyone has a pic of the 2 next to each other???

thanks!

Go with 36" TSL "SX" they are awsome!

:smokin:

The TSL is a good strong proven tire, but its outdated technology. The IROK owns it in nearly every aspect of comparison short of road wear (IROKs are soft as fawk).

And that 36" IROK has a truly measurement of just under 37"

This was mine, same tires you are considering.

I do like the sx but they are ALOT more $$ per tire!!!!
do you think the 38x12.5 will be to tall and skinny? any pics with a 38x12.5 tire next to a 38/39x 13.5 tire?

I just bought 39.5 13.5 Iroks, they arent that wide, def. not as wide as the 37 12.5 Rockers I took off.

Here is a pic of mine on 38x12.50 TSL's. I havent gotten to use them yet, as I just got them mounted up over the weekend, but I dont think that they are to skinny, and they are VERY aggressive. If you are willing to groove them, I dont see you being disappointed.

Irocks.

the 38x12.50 tsl doesnt even measure 38 my buddy has them and my 50% worn 36x13.50 iroks were close to the same hieght. i persoanlly have run the 36 and 39 iroks and like tem better than the tsl.but why is it that your looking between a 36 irok or 38 tsl ? whats the jeep have for axles,suspension etc. it might be worth your while to look used alot of people by new and dont like the tires for one reason or another and sell them cheap to buy diffrent tires.

The TSL's measure something like 37.8". That is according to Intercos website at least. The reason that they are so close to your IROCS is because the IROCS measure nearly 37" like was mentioned before. One thing to keep in mind about the IROCS is that they are a VERY wide tire. If that is an issue for you, then it is something to consider before you buy anything.

my .02 is that you will have better driveability (because of a skinnier tire), tread life, and possibly sidewall life with the tsls... Although Im biased, i prefer a skinny taller tire over a cheerio/donut looking profile.

I had iroks on my jeep and they wouldn't get out of their own way. Now I have 38"tsl on it and its like night and day. You couldn't pay me to put the iroks back on. Just my opinion:flipoff2:

well like said the 36" irok is almost a 37" tire, but i have a d44 front and an 8.8 rear with both with 4.88's, 16" coilovers etc.. I tryed looking for used ones but i live in Newfoundland Canada and there arn't many tires in the Canadain section for sale.. There are 39.5"x13.5 irok but i think ther will be to big/ heavy.... ??

but a 13.5 wide tire will fit with no issues.

Another point to take into consideration in addition to the irok being softer compound and wearing faster, is that the tsl's tread depth will typically be deeper new, as well as deeper longer than the iroks since they wear slower... definitely a consideration since you will be driving on the street a considerable amount. And IMO the iroks other than the 42s look about half worn new when compared to the tsls. Just a couple more small tidbits to add confusion to your decision. :grinpimp:

any front on pics? or it next to other jeeps?
thanks!

Seriously man, if you are building a rock rig. You want the IROKs. I'm talking from experience here, I lived in the rocks up here. I had Boggers, not quite TSLs but not far from them either, and they sucked ass in the rocks. Went to IROKs and my rigs capability went up ten fold. I was climbing rocks and climbs that I couldn't even approach with the boggers.

So heres some tech.

Super Swamper TSL bias
38x12.5x15
Tread Ply=6
Side Ply=4
True tire height=37.8"
Tread width=10"
Cross section=12.8"
Weight=72 lbs.

Super Swamper IROK
36x13.5x15
Tread Ply=6
Side Ply=4
True tire height=36.8"
Tread width=11.0'
Cross section=14.5"
Weight=66 lbs.

With that info in mind. The 36" IROKs are actually taller then the 37" IROKs. The TSL is only 1" larger which means you only gain a 1/2" extra of clearance, negligible at best. On the road aired up the IROK will be easier to turn because its weights less. On the road air down it will be harder because its much wider. In the rocks wider is better then narrower, period, its not even worth arguing. The cupped edges and the deep siping as well as the softer rubber compound in the IROKs will and does perform better then the TSL in every type of wheeling, and especially when snow and ice are involved or rocks are wet. We get alot of wet greasy wheeling up here and the guys with lockers and IROKs, TrXus M/Ts, or any other heavily siped tire are in a different league as opposed to guys running TSLs, MTRs, BFG or Pro-comp MTs, and even BFG crawlers in anything esle but dry rocks. If you are serious about making a rock rig then there really isn't even a comparison between the two tires.

Hope this gives you something to think about.

Just to add the tread depth to this post since the sizes weights etc are posted above.

Irok - 21/32

TSL - 23/32

well with the 8.8 and d44 id go either 36x12.50 tsl sx or the 36x13.50 irok. i prefer iroks but wouldent turn down a deal on tsls the iroks tend to clear out mud etc. if there is muddy type trails your on. i know plenty who run both i do wish the iroks had sidewall armor like the sx. really either tire ou cant go wrong

I never priced the 36"sx.. i might have to do that! There is a price difference of $0.22 between the 36x13.5 irok and the 38x12.5 tsl.

I want these tires for wet/dry rock, and a tad bit of mud.. but i will be driving on these tires to get to the trails..

priced the tsl sx they are right around the same price, so i'll add them into the mix! they are the 36x12.5x15 tsl sx. more thoughts??

Ive been running 36x12.50 tsl sxs for a long while now @8 years, and they work much better once they are grooved, tough sidewall as well, check the link in my signature for grooved pics.

looks like i may be getting the 36X12.5 sx. Then they will be grooved!
thanks guys!!

I think you will be completely happy with them, and if not theres always somebody looking for this tire in this size, so it shouldnt be hard to sell them. :grinpimp:
