I ordered mine Feb 23, and the order still has not been accepted by GM. I'm buying one next week from another dealership.

It’s definitely possible. Some guys are running 12.50s on the stock wheels. When my truck finally gets delivered (I ordered the d@mn thing Feb 23) that’s the setup I plan to run - stock wheels and 37x12.50x20. It will rub a little at full lock, but I’m ok with that.

Killer video man, very informative. Truck looks great. Love how the tires fit tucked inside the fender wells. Very nice!

Looks awesome man! Turned out really nice!

Man that’s perfect! Thanks!

Very nice! Yea, switching to the Toyo MTs will look pretty d@mn good. Do you by chance have any more pictures of your truck with the lift and stock wheels? Just wondering if the new cognito spindles kicked the tires out even just a touch past the fenders? I’m hoping they don’t increase the track width at all. Thanks for all the info. You have been a ton of help.

Roger that. Any reason why you are selling the Ridge Grapplers? Just like the look of the Toyo MTs better?

Awesome! Please post pics (front, back, and sides) when you are done. That's going to look really nice.

I am currently running stock UCAs, but my plan was to switch to a set of Cognitos. The guys who install Cognito UCAs with their leveling kits don’t seem to have any issues. Maybe the lift kit with the new spindles somehow interferes with Cognito UCAs. Not sure why else it would rub when the leveling kits Cognito sells (with upgraded UCAs) do just find.

Wow, that’s great news. Thank you. Those look like Ridge Grapplers. What size tires are you running? Your truck looks awesome! Also, are those the stock wheels in your pic?

Well piss! Lost another one to the dark side. I need more info from the stock wheel guys. I have yet to see an aftermarket wheel that I like better than the stock wheels, and wheels that stick out past the fenders look ridiculous to me - but that’s because I’m old (42). Good luck to you either way.

The 37x12.50x20 tires will definitely fit on the stock wheels with a leveling kit. I found two posters on here that did it and it looks great. It does rub a bit at full lock (both posters say so), and that’s why I considered the 11.50. The one posters name is gswift. Look him up and you can see his pics. His truck looks amazing. He went with the 37x12.50x20 Ridge Grapplers.

It’s not very common, but I like the “stuffed” look of the tires tucked in. I want to level the truck but I have also considered installing the Cognito 4” lift kit. Yes, I know the differences and that the lift kit is much better. However when I contacted Cognito and asked if the 4” lift kit will work with my stock 20” wheels, the tech at Cognito replied: ”While the kit allows for up to a 37x12.5 Tire on a 9-Inch Wide Wheel with 5.5-Inch Backspacing. We can run stock wheels with stock tires, but with wider/taller tires they would possibly contact the arm, and would require a lot more trimming.” I know there are some guys with Cognito leveling kits and UCAs running the stock wheels with both 35s and 37s. But can I do the same thing with the 4” lift? The only thing that changes is the new Cognito spindle. I can’t see it affecting anything, but I need to be sure before I start ordering parts. I don’t mind a little rub, but I at least need to make sure that the stock wheels and tires will bolt on and not get stuck hitting the UCAs. My wheels are the stock Chevrolet 20” wheels that are black and gray. Specs on them are: Factory 20x8.5 Wheel Offset = +47 mm - Back Space = 6.60" Inches. Thanks in advance.

Yes, please let us know how it goes. I’m in the exact same situation that you are in. I too want the “stuffed” look and am going to run the 37s. My current plan is to go with the Cognito premier leveling kit, use my stock 20” wheels, and install either 37x11.50 or 37x12.50 Nitto Ridge or Trail Grapplers. Nitto is the only company to make a 37x11.50x20. I want the thinner tire but am worried that the tires will look too skinny. The 11.50 tires are lighter and have less rubber contacting the road, so I know the mpg won’t suffer as much as the 12.50 tires. I am going to assume that the shop you found with the tires in stock are 37x12.50x20 since the 11.50s are very rare. I can’t find many pics of the 37x11.50 on a leveled 2500hd. Please take a lot of pics (both side, front on, and rear) and let us know how it goes. Good luck!

That’s a great idea. Thanks swift! Maybe the 1” difference in width will keep the tires from touching the UCA.
