If it's not too much hassle, I'd be curious to see your clearance with that setup - this is what my truck currently looks like with factory wheels and stock 275/65R20 tires.. I'd say max 3/4" clearance before UCA is rubbing on the tire with the wheels pointed straight ahead.

Now I’m confused! One says zero rubbing with 35x12.5 on stock wheels with the kryptonite stage 3 and the other saying it will rub for sure. ??

Just installed a Kryptonite Stage 3 Levelling kit on my '21 AT4 HD and I am debating between tire sizes to run on the stock wheels. Main considerations for me are; - no rubbing on frame or control arm at full lock or during suspension articulation while driving off road. - ideally no wheel spacers to make it work - trimming or tying back liners is no issue but id rather not start hacking things up beyond that. Tire sizes I'm looking at 35x12.5R20 - which clearly fit no problem as per the above post. Very similar to stock size (except wider) which looks a bit on the small side with the levelling kit (IMO). 325/60R20 - has anyone that's run this size on stock wheels that can comment on fitment? This seems like the best size IMO, also comes in factory load & speed rating which is nice. 37x12.5x20 - Sounds like these work with no cutting just wheel spacer and some trimming? Any & All comments are welcomed. Looking at the Toyo AT3 as my favourite. Unfortunately they're hard to find in Canada right now, especially in the 325/60R20 size.

This is phone related for sure, search CarPlay in your phone settings and you should be able to get it sorted.

Put my sled deck on my new ‘21 AT4 HD and connected the deck wiring to the 4pin connector in the box so that the clearance lights etc are controlled by the truck lights as they should be. Trailering app detects that it’s connected and if I tell the truck it’s a trailer, rear park assist is turned off - which makes sense. when I tell the truck it is an “accessory” the rear park assist is still turned off by default and CANNOT be turned back on unless the deck is disconnected from the truck. Not sure why they didn’t make and adjustable setting for this situation, or just enable the rear park assist when you select that a accessory is connected. has anyone else had this issue or found a work around for it? I’ve searched the manual and all the settings menus and can’t find anything.

Good info, thank you for sharing.

Great looking setup, have the same truck ‘21MY and looking at the same setup. Did you go with the 3” levelling kit that is control arms, keys and longer fox shocks? If so, how is the ride? Any trimming or removal of parts to avoid rubbing or does it rub at all? Thanks!

Thanks for the feedback Dan, from all the research I did this felt like a fair starting point considering the miles / condition and extras. It's middle to low on the blue book price range for this truck as private sale. As for the company truck, it's not going anywhere. Due to my position I can say that with certainty!

Factory all terrain wheels 20x9 I believe.

Just installed my setup; 305/55/20 Toyo Open Country ATII Extremes and RC 2.5" lift / level and found 2 bits of information for people out there; 1) Toyo rates this tire as 73lbs, I weighted them before mounting and they actually weigh around 63lbs - I find this very surprising. 2) There is definitely rubbing contrary to what others have said, The tire rubs on the sway bar at full lock (not felt liner) I will likely add some 1/4" spacers to get rid of this as its quite a rough rub due to the aggressive sidewall tread on this tire - perhaps that's why this tire rubs when others don't as the sidewall lugs do protrude a fair amount (but certainly not more than a Toyo MT which some report no rubbing with) . Its easy enough to avoid but i'm still not a huge fan of this as i'm sure it induces some pretty good strain on the front end when it rubs. Will let you guys know if the spacer cleans it up.

Those numbers for the AT2's sound pretty reasonable to me, I assume thats a long term average for that setup?

Better mileage around town than on the highway with oversize tires seems counter intuitive to me but I guess it depends how fast you drive on the highway... 80MPH is by no means optimal speed for economy so perhaps that's why! I wish i could get 22mpg on the highway, that would be right around EPA rating for these trucks. best I have gotten so far is 13.5l/100km (approx 17.5MPG) on the highway averaging around 65mph with stock tire size and bone stock truck. They are winter tires but i cant imagine that taking 5mpg off! what gives?!
