C or E load?

I’m looking at these also Horizon for my AG pro since I lifted with the Eibach springs. 285’s mounted on my F5’s. I have the wheels just need the tires.

3800 mile update
We just got back from our Colorado trip, and thought I would give you all update. Unfortunately we were not able to find any snow and had very limited amounts of rain. Therefore I cannot comment on how well the tires perform in frozen/wet conditions.
A few quantifying variables first:
- numbers include two humans and a 60# Rhodesian Ridgeback/Lab mix
- no lift (we'll get into that in a bit) or other consequential mods (I will say that the H11 -> H9 low beam swap is well worth the time and $10)
- 30mph+ crosswinds in the prairie states
On the way out to and back from Colorado, we averaged 18.9 mpg and 72 mph. This is inline with previous westward trips. Taking into consideration the hills and significant winds, I'm actually pretty happy that we saw no decrease in miles per gallon in comparison to the ATIIs. For reference: I typically get around 19 mpg on my ~60 mile daily work round trip (mixed city and highway). While I do not have a SPL meter, anecdotally both my wife and I thought highway noise was lower with the ATIIIs. This was after removing the foam sound insulation and carpet padding from the rear storage area - creating more space underneath our storage/rear leveling system.
On road performance was top notch. Good road feel, zero wandering. The balance was also spot on (and the installers did not mention any issues in getting the tires balanced).
Off road is where the tires really stood out from the ATIIs. In more than one situation in which we previously pulled the lever into 4WD HI, we kept the truck in 2WD. Driving the North Fork of the Swan River outside of Breckenridge created the most challenge. However, in conditions we experienced in the past, this time around we got much further into the drive with just the rear wheels pushing us along than we ever got with the ATIIs. Once the front wheels were engaged, we had zero problems going up extremely steep, rocky, and muddy terrain that the ATIIs always had issues biting into. Unfortunately, we had to bail when we got to the gnarliest section...which might be a good thing: we both thought that a stock rig might be able to make it up the rest of the trail, but a slightly lifted rig would have a much easier time. (any recommendations on a 2"-2.5" lift that doesn't kill on road performance??).
Ultimately, we are pretty stoked by the off road performance of the ATIIIs. The tires are so far a perfect match for our driving requirements, and I look forward to taking them out in the mountains this winter.

I’m in a tire dilemma with these. I deal with the same tire place and know the owner. So I prefer to give him the business. He gave me a 285 mounted on my SCS wheels since I lifted my 2020 Pro higher. He called me yesterday and cannot get these from any of the vendors. All out of this size. I told him I can wait till they he can get them. So was planning on getting them but also looking at the Nitto ridge grappler option he can get. But do not like the reviews for the snow on that tire. So I a decision to make.

Sounds like tire shop needs a new supplier. Regardless you could order them online and bring them to the shop but personally I would find a discount tire as they will give you road hazard and lifetime roadforce balance...and my DT pricematched anyone on the net
I’m ok with it ForRun. I don’t have a discount tire near me. Plus it cheaper to buy from him and they come with the life time rotation and balance. Even on corvette forum guys with the Michelin’s tires are having a hard time getting them for there C7’s. Because of all this COVID causing production delays. I would go with the Ridge Grapplers just don’t like the reviews in the snow.
My qualm with the Hankook is that it just doesn't seem aggressive enough for my liking and appears like it may have a pretty weak side wall. I actually think their tires in a lot of other segments are pretty good buys though (I had them on an Infiniti G37 way back plus put them on my Golf R when I was getting ready to trade it in ~6 months), so would love to see them do something a bit more aggressive down the road at some point.
Just to chime in; DT does include lifetime balance and rotation also. If one is not near you though, agree that is not a good option unfortunately.
The RG is a very different tire than the AT3 and they have generally not been considered great for snow. I actually did run the Exo on my 2012 JK and it was BOMBER in snow but is really too heavy a tire I'd say to make sense on a 4Runner unfortunately. I really wish Nitto had a 3 peak snow flake tire that didn't weigh a TON on the market in the US...

Looks great! What size did you go with?

Many thanks!
We stayed with 265s. With that said and after running around on the trails, I should have gone with 285s and done a little modification. The added height (and visual appeal) would be nice.

I had to buy early because one of my KO2s had a nail in the sidewall that couldn't be repaired. I left the nail in there until it came out on the highway and I had to change the tire. I did get the Hankooks. Dynapro AT2 RF11's. 20/32 tread depth. 285/70R17 at $187 a piece. So far so good, very quiet and smooth on the road. E-Load so I think the sidewall will be plenty tough. I don't think the tread depth will be any less grippy than the KO2s just looking at it. A YouTube review from Australia found these new RF11's to be more grippy than the old ones. I will find out.
KO2s lasted me 39,500 miles but were very poor riding at the very end.
Will be interesting to see what you think with some additional time on them. I honestly do think there are a lot of good to great tires out there these days and not many bad ones per-say.

I'll review them one day.

Anyone able to use the ATIIIs in the snow yet and can provide more review there?
I'm wanting to throw a set of 285/70/17's on my TRD rims, but Toyos chart lists 7.5 at the bottom of the "Approved Tire Width Range". I believe the TRD rims are only 7" wide. Anyone have thoughts there? Is that more of a warranty issue, or does it present legit safety issues?

I just got a chance to use them in my truck this past week in the North East.
Needless to say super impressed. I had 285 KO2s that were balance issue and terrible water traction. I sold them off the truck with about 15k on them and grabbed the AT3 in 285 SL rating.
They literally balanced with almost no weight, super smooth on highway, got some pick up back from un-sprung weight and OH YES AWESOME in the snow.
Best bang for the buck and an awesome tire ALL around, def prob going to be a go too when they wear out! :hatsoff:
