Just put the AT4 s on my fj40.
100 miles of so pavement
Much quieter than my very worn kO2.
So far so good.

It’s not so much about the make of tire as it is the rotational weight and diameter. Part of what makes tire reviews difficult is that it is rarely an apples to apples comparison. Even within just the AT4W line there are at least three different tires with the same name. You have Standard, HD, and Duraspec (and combinations of those) each with different construction and rubber compounds.
In my case, my previous Ridge Grapplers were LT285/65R18s, so 32.6 tall and 11.2” wide, and about 59 lbs per tire. The AT4Ws in LT285/70R18 LR C are a larger than spec at a full 34” tall x 11.5”w and weigh 69 lbs. That’s a huge jump in rotational weight and a high percentage of that weight is in the very wide and beefy tread 1.4” farther from center. So it takes much more torque to accelerate the AT4Ws in that size.
By comparison the LT275/70R18 E KO3s I replaced them with are advertised at 33.2x11” (but usually run small) and weigh 59 lbs per tire. They are the same weight and slightly taller and narrower than my RGs, so not much difference rotationally.

I agree weight is a factor, although I'd wager the larger factor at play here is lost gearing with the larger overall diameter tire. I've been through enough wheel/tire packages and gears on this rig, and into almost 80lbs tires. Tire weight is not as significant as it's made out to be on these boards. Same with braking. It's the lost leverage and wheel torque that is the primary factor over rotational weight/inertia.
Get the gearing right, and the rig will still feel strong and tow like an ox, with heavy 35/37s.
I agree 100%! Thus my original comment about those tires really needing a regear I wasn’t quite ready to do. I think 33s are about the max I’d go on the 200 series without a regear.
Rock Warrior wheels with Fallken AT4W 285/70R17 SL installed today.
It's likely between these or the Michelin Defender LTX M/S2 when I next need tires. Both come in SL or XL load ratings for 285/65R18.
Other contenders are the Bridgestone Dueler Ascent in LT285/65R18 (E) (because they're relatively light for an LT) or the KO3 in LT285/65R18 when it comes out later this year in load range D.
I was considering the SL 285/65R18 Duratrac RT, but they didn't do very well in the new Tire Rack all-terrain comparison.
