Just put a set on today. 265/70/17s SLs.
Too soon for objective data points. However, subjectively the AT IIIs look more aggressive than the previous version, and maybe a touch quieter. We'll be taking a trip out to Colorado towards the end of the month and will likely get them muddy and snowy.
I have the P285/70R17 on my pro. They are unbelievably better than the Nittos that came stock so far for me although I only have about 500 miles on them. I could not be happier with my decision.
According to my tire guy these are some of the best road force numbers he has seen for a truck tire. He also talked a lot about checking the DOT dates to make sure you get a recent set. A lot of the tires from Discount sit in a warehouse for a long time and they have issues with balancing (that’s what he said at least).
AT3s have only been released since March 2nd, so none have been warehoused too long as of yet...
For sure... but always a good idea to check the DOT![]()
Got mine the other day in P285/70R17. I didn't realize how smooth going back to P would be over the LT C I had been running. My off-roading is limited, but the truck will still be the primary driver in the Rust Belt Winters.
There's some rubbing even with the lift (which is only about 2"). I trimmed about 1/2" off of the bumper on both sides and had to push the passenger side front wheel well liner forward too. The driver's side is rubbing a little on the mud flap. I don't want to cut the mud flap until I'm sure it's just the mud flap and not working on the body mount.

Thank you for contacting Toyo Tires USA. The Open Country ATIII in size LT285/70R17 in C/6 weighs 54.56 lbs. and the E/10 weighs 54.74. Both offer the standard 2 ply sidewall with the E/10 having a stronger tread casing.
We do not have information pertaining to the K02's sidewall information.
Both the C/6 and E/10 offer a 50,000 mile mileage warranty. We do not have testing related to the wear on both as that will be dependent on the application and types of use.
Glad you like Toyo AT 3!
Can you please elaborate on what specifically “unbelievably better” on those vs. Nitto? (Just trying to get as much info as I can :sorry:).
And I am assuming you went from stock size Nitto, correct?
Yes I went from the stock Nittos on the pro to the AT3s. I have less road noise, what feels like better acceleration, and am showing about 0.5 mpg better on the dash. This of course is counterintuitive to having a lift and larger tires put on. I almost wonder if Toyota had aligned it correctly when I bought her.
The biggest difference was during the rain the other day... way stickier than the Terra grapplers. I wonder if all of these things are the reason they updated the tires on the Pro for 2021?
I swear the press photos for the 2021 (in Lunar Rock) still had Terra Grapplers on them. What are they shipping with?
When I had my Terra Grapplers pulled at Discount Tire, they were amazed at the DOT code given the fact the tire has been out of production through standard channels by Nitto for awhile. Appears Nitto has done batch runs solely for Toyota for OEM use the last year or two...
My understanding is that Nitto has updated the Terra Grappler tire itself specifically for Toyota in order to improve it over last years model. There was mention of it in a couple of articles I read discussing the updates.
