    I posted this over at Pirate and thought I should post it here too.

    YES - They are molding a 42 real soon, its definately in the design stages. See more info below.

    Okay, firstly I am not sure how many of you are aware of the tire molding process so Here we go! Interco did not release any mold dates and Please, don't go ringing their phone off the hook about this - they are doing their part. Molding a new tire size takes time.

    Here's the procss. First they do the design on paper. A plastic model is casted of various sections of the tire to see their design in 3D. These "Model Sections" are tweaked and fine tuned and finally transferred to Mold Drawings (back to paper). From there, they are sent to their mold shop where they make whats called a "Green Tire". A Green Tire is basically a carcass that looks similar to a drag slick. This is pressed into the mold and cooked. It is taken out of the mold and cured. Then you have a "Sample Tire". This Sample tire is cut up to check it internally for flaws in the molding process and to see how molding affects the size designated for the Green Tire. If there are flaws, they have to go back to the drawing board - test and test more until they develop another Sample tire. After the Sample Tire is perfected, it is time for testing on the Test Wheel. If it passes on the Test Wheel, then it's time for production. SO, theres your tire molding process in a nutshell. Now you can see why a tire takes a while to develop from conception to sale on the showroom. Most tires can be developed quickly depending on your molding process. I will not disclose the details of their molding process, but I can say its first rate and very well thought out.

    Few of you might not know this. Radial and Bias tires seldom use the same mold. So, the 42" IROK is slated for being molded in a "Bias mold", meaning it will be a bit meatier, but will also be lighter than its TSL predecessor. So, for those who whine about it having shallow tread depth, this should be a bit deeper in tread.

    I have some Weights for you:

    39.5" IROK weighs in at 76 Pounds.
    39.5" TSL weighs in at 94 Pounds.

    Granted the IROK is a shallow bit narrower than the TSL, it is lighter for competition.

    The 42" IROK has been estimated to weigh 94 Pounds.
    42" TSL weighs in at a heafty 104 Pounds.

    Of course, this is an estimation - I would guess less for the 42" IROK, but we will see.

    Estimated cost for the 42" IROK should be around $238 - $258 range.

    Again, I got this straight from the source. NO HERESAY. But, please be patient and don't ring the phone off the hook. They will be updating their site real soon with info.

    I may try to get an early production set of 42" IROK's for testing and will post pics and data ASAP. Give me a month or so.

    They aren't making these for a 16" wheel perhaps? I see they make a 39.5" in a 16" wheel.

    Probably not going to be available for 16.5 rims, eh? That size seems to be going out of style, but it sucks for those of us that are running Hummer wheels. Oh well, time tostep up to 17s or dubs I guess. /forums/images/graemlins/grin.gif

    We didn't discuss rim size. I will try to persuade Interco to keep the 16.5" rim size. /forums/images/graemlins/thumb.gif

    They did talk about a 20" rim size which is pretty popular. I told them I would probably wear out my 40ies and then get the 42's. /forums/images/graemlins/deal.gif

    if you are talking with them can you suggest more 16in rim sizes? tsl's and boggers the biggest you can get is a 38in tire and the new irok 39.5in but thats as big as they make for 16's /forums/images/graemlins/angryfire.gif so more bigger 16in sizes would be sweet /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    I would suggest something like a 42x15.5x15 or 44x15.5x15 as being a good size for my needs (AZ rocks). 44s are just too wide in the TSLs...

    I have spoken directly with Interco as well. They told me that the 42x13.5x15 will be first off of the molds, then it will be a 42x13.5x16.5. After that they will looking at possible the 16" and 17" rims, and even possibly a 20" setup. /forums/images/graemlins/thumb.gif

    anyone know if there are plans for smaller Iroks? I notice they dont have anything between 35 and 39.5... what, no 37 or 38.5? these tires are kinda cool cause they are light (compared to TSLs anyway)... be neat to run em on a light buggy.... /forums/images/graemlins/thinking.gif
