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.


With the 35x12.5 you won’t have any issues other than the kryptonite control arm. The wider tires will rub on them with your stock rim offset. 11.5 wide tires will work. If you want to keep the rims, you will need spacers with 12.5 wide.

Not the best pic, but this was right after she was done, and I was dropping the old tires off at the old mans for him to give to a friend..NO rubbing, NO cutting/bending anything..

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.  ??‍♂️

I believe the other guy has after market wheels with high offset. This truck, the white one in the pic has the Kryptonite stage 3 with Fox 2.0 and stock Denali wheels. I have 0 rub..

This was rubbing with stock rims. Maybe it’s the tire selection because they rubbed with Maxis MT 35x12.5. Had to get new rims.

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.

I took a pic to show you the clearance, I didn't measure but it's not allowing me to upload it for some reason. But from my pic its really not all that much closer.

I’m sorry but I think you will rub if you bump up to 12.5 width. You have 3/4” clearance now. Stock tires are 10.5” wide if I remember correctly? So adding 1” to each side will certainly make them rub.

I’ve been running the Kryptonite Stage 3 kit for a while now with 35x12.5x20 on 20x9 with a +10 offset with no rubbing issues at all, just enough tire poke to give it a more aggressive look that it needed! 3a7d03ac2becffde0d41333748b0d142.jpg280ef74c8335a15a9348dc9a51350cc9.jpg

    • I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.
