Interco Faithful Review of the Coblat M/T Mudd Terrain Tire

[@raymondkasler1837]

They will forever be known as Ground Hawg's That is all.

[@IntercoTireCorp]

The name Ground Hawg was sold along with all of Denman's Intellectual property (mainly molds). The company that purchased them reportedly scrapped all of the light truck molds, including those for the Ground Hawg and Ground Hawg II - it is also reported that this company has no intention of ever producing a light truck tire. No molds, and the name belonging to someone that has no intention of selling it, at least not for a less than a small fortune, equals no more tires called Ground Hawgs in the near or distant future.

Old School Hawg's, would have been suitable name.

[@randymagnum6680]

I grew up around the mud pits with old school tires like ground hawgs, original tsl swampers, buckshot and gumbo mudders. Love the classic look

[@CRyan-iz3wr]

Randy Magnum the old ground hawgs were made for the Mel Mcdaniel, Waylon Jennings crowd. The sizes they offer in these are for Luke Bryant' s wimpy jeep.

[@randymagnum6680]

C. Ryan agreed, the kind of people who only listen to classic country now, since country is dead, choked to death in a pile of affliction shirts and chain wallets

[@jdub229r]

Yep, I might have shed a tear when I found out I couldn’t buy Multi-mile RVT bias ply directionals in the early 90s. Had a little softer tread than Ground Hawgs, similar pattern.

[@rudedogii]

I bought the last set of 40x17x17 Ground Hawgs from Interco and my buddy had a set 38x16 Radial Ground Hawgs. Both had a much more aggressive tread than the cobalts.

[@IntercoTireCorp]

Two totally different tires. Both of you bought Bias ply ground hawgs.... Cobalt's are radial tires and are not ground hawgs. They have as deep a tread as a radial tire can support. Also we made them quieter by taking the blacked end of the lug and scooping them. We have the 17/40-17 size in development - as a bias.

[@rudedogii]

@@IntercoTireCorp My tires 40s bias ply my buddy had the steel belted radials. The radials ran smoother and quieter! I have eight years in the tire business. I know my tires.

[@IntercoTireCorp]

@@rudedogii Then your buddy bought Ground Hawg II tires, and their lug depth was not the same as your bias 40s, nor was the depth of the side lugs. I'm sure you know your tires, but I'm pretty certain I do too. At any rate, we appreciate you buying them then, and hope you will like the new sizes of Cobalt's that are in development. We also hope you can appreciate why we made changes and why they are called Cobalt's and can't be called Hawgs.

[@steveogregg6940]

Much deeper tread on the ground hawgs.

[@IntercoTireCorp]

@@steveogregg6940 Yes there were Steveo... you can run a deeper lug on a bias tire... however, if you take the squared end off the lug of an old GH, they don't look nearly as aggressive or deep. That's what we did with the Cobalt. It allowed us to quiet the harmonics on a tire - something that is highly requested feature (A tire without a lot of road noise). If you still want a hard core off-road tire with deep lugs look no further than a Super Swamper TSL or Bogger.

[@cheddafaceboiii8252]

So are you guys still making the Thornbird tire? If so. Some product reviews of it would be really nice.

[@kevinmoss970]

Firestone used to have a similar pattern called the firestone SAT.

[@IntercoTireCorp]

Firestone did offer a tire called their Super All-Traction tire, but it was a farm/co-op tire. Although it did indeed look similar to that of the GH and the Cobalt, both of these were/are light truck tires. An LT and a farm/co-op tire are not nearly the same in construction.

[@kevinmoss970]

Those old cross ply firestones were a handful on the road. And nearly lethal in the wet.

[@Yo-mamashouse]

will you ever release a 15 inch cobalt

[@murderymofo2102]

Give credit where credit is due. I'm not knocking you guys at interco. I've been running either tsl's or boggers for 20 years and have not one complaint.... until now. Ground Hawgs are legendary. They were the original bogger. They set the standard for ultimate mud slinger. I am super excited to see the tread pattern on the market again, but pay Denman some homage for f'sake. I mean... I guess you kinda are by using their design... but don't act like you invented it. That tread has been tested far longer than the 3 years you claim. That tread has been certified legit king of the mud hole since before most of you could walk.

[@IntercoTireCorp]

Obviously you don't know your Tire Industry History very well MURDERYMOFO. Then again not a lot of people do, so we're not knocking you for that. We'll try to briefly break it down for you. For privacy sake I want mention his full name, but a man named Tom L. actually designed the original Ground Hawgs for Denman. Tom is also the President of Interco's M&H Racemaster Division. In case you didn't know, M&H is Interco's muscle car, street and drag tire division. It was founded by the late Marv R. (Google "who invented the Drag Slick"). Every single Interco LT and ATV/UTV tire tread pattern has been designed by Warn G., the owner of Interco. Also, Interco was also large stakeholder in the Denman Tire Corporation, and the sole distributor for the Ground Hawg and Ground Hawg II. For decades many of Interco’s tires were produced at the Denman plant. Prior to filing Chapter 7 liquidation, Denman's light truck tire division sales, namely the Ground Hawg line, had struggled due to quality issues. In the end all of Denman’s intellectual property (molds, brands and logos) were sold in a bankruptcy sell to an undisclosed company whom, to our knowledge, sought only the molds and patterns for Denman’s construction, agriculture and mining tires and scrapped the light truck tire molds soon after the purchase. This means the original GH and GHII molds, and tires, are gone forever. Interco’s Cobalt MT was developed from the ground up to be a modern light truck tire. The tread pattern does resemble the GH, which resembled an old Firestone Co-op Tire. It was our intent to build a modern tire for use on today’s Trucks, Jeeps and SUVs and we honored the past by using an altered version of retro tread pattern. We cannot use Denman’s name or any of their registered trademarks in our advertising, so we cannot give them any credit. We are under the impression those that know it - know it, and are happy that it is even back on the market at all, regardless of the name that’s on it.

[@IntercoTireCorp]

@@murderymofo2102 It's a long and complicated story, and We try to limit our "retelling it" but are happy to when needed. The Ground Hawg was a great tire, and it was sad to see it go away. We were delighted to "reinvent the wheel" with the Cobalt. We are currently in development of new sizes (to match those that people fondly recall such as a 17/40-15,16,16.5,17 and 20) to complete the line. We've listened and even added a few 32s to the tread depth, although they are as deep as a radial can go. Interco is one of the few remaining privately owned tire brands left in the world. We started this whole light truck tire industry when we introduced the first L78 that was specifically developed for light trucks, and if we have it our way we'll be last... We our proud to be a debt free company and you don't have to worry about us ever selling out. Thanks for being Interco Faithful...

How would you rate this tire against the BFG KM3? I used to have a 1970 Ford Custom 100 "Heavy Half", it had the Ground Hawg and was the best 4x4 I ever owned hands down. Now I have a 97 K2500 with BFG KM2's. I am amazed at the KM2's performance in the mud but it's time for some new tires.

[@jbird1173]

Ground hawgs were alot more agressive looking and the tread was alot deeper. These look similar but hawgs did not have any siping in the center tread.

[@camoadventures]

I hope this tire is produced in 15" and 16" or even a 17" rim size so the non mall crawler crowd can enjoy them too ... Definitely would buy a couple sets.

[@IntercoTireCorp]

17" for sure... and 15" and 16" wheels haven't been standard OE equipment on full-size vehicles for the last 22 some odd years. Yes, some smaller vehicles, Jeeps and SUVs, and foreign trucks did come with 16" wheels as standard OE equipment in that time frame, but the vast majority of that group has with a 17" a standard OE standard wheel since 2010. It's not that we don't make tires for 15" and 16" Wheels - heck we are the only company that really does anymore and we have 200 models for that wheel size range.

[@IntercoTireCorp]

​@@okigojuryu GM stopped offering the 16 as an OE set-up in 1996. You could special order them as a factory option. Ford Followed suit soon after. Yes, Rangers and S-10s still came with a 15 or 16-inch wheel, but as a whole, OEMs have not used anything smaller than a 17 as standard equipment since 1998, or about. with any regularity, for LTs at least. Jeep stopped using the 16" wheels as standard equipment about 10 years ago opting for a 17" to help accommodate larger breaks. The funny thing is that we offer more 15, 16, and 16.5 options that all other major brands combined. I think we are the only tire company that still has more than a couple of options for a 16.5, and we have over 75 options.

THE MOLDS WERE NOT DESTROYED. THE COMPOUNDS AFE VERY CLOSE.

[@IntercoTireCorp]

Actually, the molds for the Original GHs no longer exist (as far as we know). It's a long story. The Cobalt M/t is very similar in appearance to the old GH tires, but they are different as well. They are radial constructed tires made for double-duty vehicles (on and off-road driving). the sidewalls of the Cobalt are slightly different as well. the shoulders of the lugs are scooped to reduce the howl that the OGHs made. The main difference is the construction of the tire. The Cobalt actually has a better-constructed carcass and was a ground-up reimagination. The Compounds are different too. The OGHs had a very hard compound, the Cobalt is a tad softer to help with ride quality. Hope this helps a little bit.

I wish someone would take a tire and cut it through the center or radius to show the rubber thickness across the whole thing!!!

[@IntercoTireCorp]

That is actually proprietary information about the construction of our tires. Unfortunately, it's one spec we don't divulge. When you groove a tire though you alter its original specs. We don't actually suggest it. We'd prefer you just buy a new set of Swampers when the time is right. Come on man, my kid wants to go to college. :-)

how does it compare to the original Trxus M/T?

[@IntercoTireCorp]

That's a hard question to answer Bizno... The TrXus M/T is one of the best all around radial M/Ts on the market and comes in many more sizes than the Cobalt... The Cobalt M/T is great in most all general,moderate off-road conditions. They pull like a MT should pull. The Cobalt is super quiet on the road, on larger heavier rigs they have a slight whine to them, but nothing that the radio doesn't drown out and or causes issues hearing a phone call. They also wear and balance very well. The TrXus M/T is great in any off-road condition or terrain. They are also great on road, but the CObalt is better - except in the snow or rain. the TrXuS M/T is by far the best M/T in the snow out there. You can't go wrong with either tire as a double duty option.

Considering the mileage they are capable of getting, that they have the same tread depth, and fall in the same price for their size range as many other radial M/T tires offered by other major brands on the market, we feel that the Cobalt M/T is an excellent value... The current models offered are also made in the U.S.A. which is not something not all of the other competing brands can say.

Tread depth is less than the old ground hawgs.

[@IntercoTireCorp]

You are right and wrong. the 35 and 37 OD steel belted radial Cobalt Ground Hawgs were built not to be a revival of the old Ground Hawg, but rather a modern M/Tire with a retro pattern. Therefor the first two models (35x12.50 and 37x14.50 - the two most popular tires for daily driver trucks in the U.S. since 2007). Each model has a 21/32 tread depths, 4/32 (1/8") less than the Original GH bias and deeper than the Original GHII Radial., but the same or slightly more than most M/T on the market today. The 38.5x15 and the soon to be released 17/40 Models both have a tread depth of 28/32. This is 3/32s deeper than the original GH. The tires used in this review do have s 21/32 trread depth. However, for a tire meant to compete with all modern (made in the last 25-30 years) it has the same tired depth but clearly outperfoms them. The new design of the Cobalt Ground Hawg M/T makes it a perfect daily driver tire, that weighs less and is much quieter than the original, that last as long if not longer than most tires in its class and balances well and rides smoothly. No, it is not the old Ground Hawg, it's better in many ways. As intended.
