i wonder if the harder diameter rubber is the main factor in improved MPG. Very interesting thread !
Been going back and forth between these and AT3 for Eastern Sierra and Panamint/Death Valley and Great Basin offroad trips, and the hundreds of miles of asphalt I have to roll on to get there. Have you rolled thru those areas yet, loaded up (not too bad) and aired down? Plan on keeping my '06 LX mostly stock except for tires, eventual Slee Step-Slider and the crap I need to disappear for a few days at a time, comfortably.

I’ve had them up in big bear, out in AZ and through southwest Colorado and they have been pretty amazing. Not to mention the extra range is nice. I get 100mi extra per tank with these vs the duratracs that I had.
For airing down I was dropping to ~15psi on the duratracs and these I only drop to 25psi off road. The sidewall isn’t as stiff which make the ride both on and off road much more comfortable.
Would highly recommend
If you are doing a lot of super tech in sharp rocks the LT may be a better route though.
What PSI are you find works best for daily driving on road?

I’m currently at 40psi. But been playing with pressures on road between 32 and 38psi. Lower pressures have higher steering effort, and are a bit more comfortable as they absorb more road inputs. Higher pressure has less tire deformation and roll, and can result in better mpg. 40psi seems to be at the very high end for daily. I have not done a footprint/chalk test to look at each pressure yet. Placard is 29 psi front and 32psi rear. I think I’ll probably settle in the 32-35psi range for all around.
I bought a set today and they’re great. You were right about rolling resistance. It’s noticeable; particularly in the mid to lower speeds. It just seems to glide along much better. I’m coming from a set of BFG kO2s in 275/70/18 and the weight savings, less harsh ride, and what I assume is going to be better overall economy make these a no brainer.

Congrats on the new tires! Have any photos to share??
Nothing great yet

Heck yeah! They look great! Do you miss how the KO2s looked?
Absolutely, but then I shut my driver door and that fades away with a driving experience that’s better in every way.
For the last 20 something years, I’ve always thought the BFG look was iconic. I truly do love the looks.
The manager at the shop I bought them from went out of his way to tell me their quality control/ability to balance has gotten worse with every iteration of the BFG A/T.

Totally agree with you on the looks aspect. They do look so beefy.
I also saw that the KO3s got a bit heavier. I wonder if the added durability is impacting their ability to balance.
I just put AT3s on my 80 series, hoping to strike a balance between fuel economy, road noise and occasional offroad performance. When I plugged the load numbers into the Toyo inflation table, I came up with about 34 PSI as the ideal inflation pressure. The installers inflated them to 40, which made them feel a little stiff.
You made the right decision. Absolutely love these on my 80 - haven't missed a beat.
Great looking truck. I have those wheels on my black 200. Question, what kind of spacers are you running to make them work on the 100?
Also, questions for the forum: any more updates on the EV tires?
And, thoughts on 275/70-18 vs 275/65-18? It appears the the 65 is slightly lighter and is XL load range vs. the 70's SL range.
I went with 1.25" BORA spacers (aluminum) all around. Those seem to be one of the more common choices for Tundra wheels on a 100.
Not to derail.. but the yoko at4 SL is another options.
33” about 43 lb each.. ride like butter.
Not brotruck aggressive (which I like) performance great so far on my tundra . A little hum though but really minimal

I have them in 35 11.5 17 .. with 4.88 gears. I got them because I am mostly road / highway.. and thes is what the LX550 overtrain uses. They are very nice riding tires.. and did wonderful in deep sand.. have not done more off roading that that. .. Highly recommend.. someone told me they were "highway tires".. well compared to Muds maybe.. but they seem to be a nice balance.

I have about 8k miles on my EV AT3 tires on the 100 series now and they still look brand new. Not even 1/32 worn yet. Super impressed.
Still getting consistently between 15-17mpg depending on more city or highway driving.
I have a cross country trip coming up in a few weeks and will be doing some trials through Colorado and Utah and will report back.
Looking at dropping pressure slightly to improve ride quality.
As far as 275/65 vs 275/70 - I like the look and better rollover of the 275/70 - however when I had 275/65s on my truck the gps speed and speedo were perfectly accurate. Which was nice. I’m about 3% off at the moment with the bigger tires.
