It has nothing to do with any nozzles; it’s closing up the variable vanes.

I think it’s not fair to compare any P rated tire to an LT, especially with an E rating, which may add weight but also a significant amount of stability. You don’t read much bad about the AT3’s online; they seem to be a home run tire for Cooper. I saw a set of XLT’s on a Cummins Ram over the weekend; from the side they look tough, but to me the tread still looks like it belongs on a boring delivery van.

You are right; I meant to say 4.10’s, and corrected my post.

Can’t knock that👍

No need to overthink this. Your Duramax truck does not have 4.10 gears.

Do you really think a stock size tire is going to weigh 109.4lbs?? What do you see them doing differently to have a tire weigh THAT much more, when E-range at’s a size or two above stock are hovering around 60lbs?

Big truck, not enough power. Don’t overthink it.

I’d love to see pics of that setup; I want to do 1”-1.5” at both ends and 275/65R20’s on mine. UltraTerrains, Grabber ATX’s, or KO2’s are my three choices.

You should be using the tow/haul button whenever you’re towing, and not consider it for use only at low speed. It will adjust things like shift points, shift firmness, torque converter lock up, and other things I’m sure. Don’t get your hopes up about a tuner for a naturally aspirated gas engine. You’ve got a large vehicle with a small engine, and I’d bet gearing that isn’t very towing friendly. You should be prepared to run premium fuel with that tuner as well.

Your pictures and link aren’t showing up.

Where is this harness located? Does the door panel have to come off?

Face palm on my part... This is usually the stuff I notice immediately, too. Makes perfect sense and I’m sure you’re right and that is the case with the readout being in degrees. Duh....

How accurate do you suppose the inclinometer is that’s found in our off-road screen? I noticed on a few occasions during my trip out west last year from Ohio to West Yellowstone that when going up grades, it would only read 4% or so when going up a 6% grade. On the way down, sometimes it wouldn’t budge below 0%, unless it was something more drastic. Not a huge deal, but I have a feeling mine is 2-3% off. Has anybody else seen the same or similar?

Did your numbers for the DMax Denali 2500 come off of a door tag? What cab/bed configuration? My 2018 2500 AllTerrain HD crew cab, regular bed diesel has a payload of only 1,984lb. I can’t imagine a Denali being any higher; the 2017 I looked at sure wasn’t.

Ended up ordering a WeighSafe LTB6-2.5 with stainless balls. Played the reduced sleeve game for the last time yesterday towing a steel U-Haul trailer thru my neighborhood clanging louder than a church bell.
