Nope, nobody does yet. I read about them on a couple forums and saw a YouTube video recently from SEMA where one guy was probing the Toyo guys about them. That video was soon removed and my comments about the upcoming AT3 deleted.

I appreciate your guys’ replies. I tell ya what; if the KO2 had both a mileage warranty as well as the 3-peak rating (like the Grabber ATX does), I’m sure it would be a no brainer for quite a few people.

Have you ever considered that the mileage increase you’re seeing isn’t accurate as a result of how the Banks inline tuner operates? Is the increase you’re seeing hand calculated?

Did you get the 3-peak rated or “DT” version?

I am interested in replacing the 265/60R20 mall-terrains on my 2018 All-Terrain HD Duramax with 275/65R20, and the KO2 is one of the tires I’m interested in. I’m aware of the myriad of options; but for the sake of this topic, I’m only concerned with the KO2. I know and understand the differences between the two specs; I’m also aware of the fact that only the DT version carries a mileage warranty. My truck is not a daily driver; it’s well-maintained, and I don’t drive overly aggressive (heavy on throttle, tire spin, etc). I’ve got a little over 15k since new last year, and the factory bologna rinds still look new. I live in Ohio and travel during the winter for snowmobiling trips to areas like the UP of Michigan and out west, sometimes pulling enclosed trailers. Stability & snow performance is of strong consideration for me, along with the all-terrain tread. Getting good mileage out of them is important, but maybe not MOST important. My question is this; considering the above information, would you prefer the 3-peak rated KO2? I’m leaning that way, as I feel it fits my overall needs better, but will be disappointed if I spend $300/tire and they need replaced in say 30k miles. Thanks!!

It’s amazing trucks have served us this well this long without magical differential covers. It’s a wonder so many trucks are still on the road.

Have none of you guys read the owner’s manual? It enables the manual shift buttons on your gearshift lever. It will limit whatever gear you select. Shift into that mode cruising along at 60mph, and it will show 6th gear. In the older trucks, it was shown as “M” instead of “1,” which makes a lot more sense to me.

The Cooper AT3 XLT doesn’t carry the 3-peak rating, though. Seems like the combo you described is the holy grail for the all-terrain tire world. Toyo’s got an Open Country AT3 coming soon; as well as Maxxis Razr AT that are both said to have a mileage warranty and 3-peak rating, so that will add two more choices.

I wondered the same thing; guessing it’s due to the lighter truck with a 6.2 that puts out power in the same ball park as the Whipple numbers posted earlier. I like the idea of a clean supercharger install on a new truck; however at the cost of entry, you lose not only your warranty, but also most of the cost advantage over buying a diesel to begin with.

Thanks for your reply; good to know it’s not just me. The sunroof option isn’t a box I’d check if I were ordering a new truck (picked mine off a lot), but it would be nice to use it and still hear myself think. I wonder if there’s a vent shade or something offered for our trucks. Edit- I do see sunroof wind deflectors available, but only universal models. WeatherTech only makes them for 1500’s, for example. My guess is that it’s due to the clearance lights on HD models.

First of all; I get it that it’s a big truck without good aerodynamics. I find that the sunroof in my 2500HD is really noisy while open; like having a window down, at anything over 40mph or so. Is this the case for anyone else? Not that it’s a fair comparison..., but my wife’s BMW is damn near silent at most speeds. Hers has a hard plastic air deflector, while mine has some sort of fabric mesh. The sunroof is not a big selling point for me personally, but I would drive with it open more often if it were worth a crap.

By the way, your truck looks great. I also have an AllTerrain HD, but in black.

It’s my understanding that the amount of threads remaining on each side doesn’t necessarily have to be equal and that every truck is usually a bit different.

This guy gets it!

I’ve never heard of Filmco. I’ve treated mine twice with Fluid Film since purchasing it new last November. It’s true that some products can soften the waxy coating that GM applies....oh well. I did enough digging about a year ago and found the manufacturer of the coating that GM uses and where you could purchase it. I’ve read where guys have used heated crapper wax, old oil, all sorts of stuff. I chose Fluid Film because it’s readily available and somewhat reasonably priced; I bought a cheap undercoating sprayer off Amazon to spray it, and it works great.
