2023 Stock Z71 with 285/60R20

[IronWill42]

Stock suspension Z71 Suburban with 285/60R20 Cooper Discoverer AT3 XLT.
These are one size wider than the stock tires.

I couldn’t find any information if they would fit without rubbing. I’m here to say they fit great - no rubbing anywhere.

(I also have the 4 take off tires & wheels in the back of this photo - weighing down the rear a little)

Nice rig for sure! Like it better than that little ford over there lol ? Beautiful home as well!!

60 sidewall being a ratio of the tread width means you've got a taller sidewall/tire overall as well, roughly 0.5" taller. I've been eyeballing some 34s so this is encouraging. Just a sneeze away from a 35 but it's close enough.

D-mn that looks good. I am going with these same tires when the stockers are done. Although I am looking at 305/55R20, a little taller but still a 33". There is a thread with a Satin Steel AT4 with 33/12.5R20 Nittos with no rubbing.

@IronWill42 I know this is an old post but wondering what you think of the at3 xlt’s with some miles? I’m most interested in highway feel between 65 mph - 75 mph if you’ve spent time there.

I’ve run a lot different somewhat aggressive AT’s. BFG’s, Nitto’s, Toyo’s, Goodyears, Coopers (Rugged Treks). All have had some degree of vibration on the highway and I’m really wanting a smooth tire. I’m on the highway all the time for my commute these days. Roadforce balanced all of them more times than I can count and just couldn’t quite get the “smooth as glass” I hear about all the time. These Coopers AT3 XLT’s have the most highway looking tread, still with a meaty look, and if they’re no better than the others I’m afraid I’m looking at Michelins and will be sad every time I look at them haha

Actually, the 285/60/20 is taller than the 305/55/20. The 305 is a smidge wider though.

Check out the falken wildpeak at4w! Ive had the at3w on my power wagon and the wifes denali and they are very smooth. The new at4w is basically the same with a more aggressive sidewall (hd 3 ply on some sizes).
