I posted pictures on an earlier date but I got new tires.  2019 RST, 2 inch level, with Black Rhino Apache 18x9 and Cooper AT3 XLT 285/65-18. 

 

How did the larger tires do? It looks like your english dimensions went from 32.6x11.2 to 33.2x10.8. Did you go narrower to fit the larger diameter? What's your wheel offset? Your running black rhino wheels and it looks like they almost all run -12. How's your poke? Sounds weird asking that, how much of your tires sticks out of the fender? Would you mind posting a pic showing the wheel edge to fender?

 

I have been leaning toward replacing my stock 18"rims with 20s and going to 275/60/20 (33x10.8) this would give me the same sidewall as stock but larger wheels and tires proportionately. Further the debate on offset vs stance. Using a 0 offset and 11.2" tires should align the backspacing up with stock, just slightly larger. Conversely a -12 offset and 10.8" wide tires should be the same backspacing with a less aggressive stance look and likely better fuel mileage due to less rotating mass and surface area friction.

 

For those with stock height Chevy's I've been combing thru to see what fits and here's the list I have so far back to middle of August. Blank spots are non-definitive data as in they didn't specifically say in their postings. I'll dig a little further back and post a new list again later.

 

Stock 2020 Chevy RST with Z71 came with 265/65/18 (31.6x10.4")

Had the 305/55/20 ridge grapplers installed last week. Ride is a ton better than it was with the 295/60 E load rated ridge grapplers. The 305s are D load rated vs the OEM C load rated so they are still a bit stiffer than OEM but still the 305s are a 4 ply tire and softer overall. The visual difference on the truck is so small that I cant even tell the difference so didnt bother taking more pictures. I will say that even with some minor trimming of the mud flaps, the 295/60 had some minor rubbing at full lock. There is 0 rubbing now with the 305s. Even though the the 305s are 1 inch wider (11.5 vs. 12.5) on a 20x9 they are right about 12 wide. Im guessing that on a 20x10 they would be closer to the 12.5. With this change my speedo is also back to normal (was off by 2-3 mph depending upon speed) and I removed 60 lbs of rotating mass (15 per wheel/tire). This seems to be the sweet spot for my truck now so hopefully others with a Denali who are contemplating doing something like this will benefit from this info.

Just wanted to thank you for all of this  information.  Super helpful.

20” GMC wheels with Toyo Open Country AT3 275-60-20. These tires ride like a dream. Not as aggressive as my KO2 but I really like these toyos.

2020 RST

3.5" Rough Country Lift Kit (lift only - not leveled)

Fuel Vandal Wheels 20 x 9 x +1 offset (I think)

Toyo Open Country A/T  305/55/20

Little trimming on the inner side of the mud flaps

Rubs just a touch when turning in reverse

I basically copied one of the members here.  I like it!

285/65R20 (34.6x11.5) Cooper Discoverer AT3 XLT, 2019 Sierra SLT 6.2, OEM SLT Wheels, 2 inch front level, 1 inch rear block. No rub in drive. Rub at half lock in reverse. (Anyone know why these trucks rub only in reverse?) I'll be removing the mudflap bracket and zip tying the liner back to alleviate that rub.

Just wondering - what do you guys think the best budget off-road wheel and tires are? I will be swapping my wheels out once the tires become worn, but am debating getting a set of nice take offs vs. new off-road wheels.

That looks great.

 

Tires rub in reverse due to the rubber bushings letting the suspension shift forward just enough, and the front end can dip down just a bit as well.

Traded in the stock Bridgestones shoes for the Nitto terra grapplers. 285/45 r22 week ago Friday. Took them for a fresh snow drive today and they worked great.

Used illustrator to mock up some wheels. I like bronze in theory but it's incredibly rare to find a set on a dark blue T1. I just had my tow mirrors installed and shell is due any day. I'll redo this with a new photo soon. I also played around with coloring the Z71 logo to match the bronze.

These are KMC KM722 Technic in bronze and grey for reference.

Is that stock suspension still?  It looks like its been leveled ? 

Its leveled in the front only, it rubbed a little bit so I had to get it done.
