I know this discussion is beaten to death. But I haven’t seen this. Will a 285/60R20 on a stock wheel fit on a stock 2021 trail boss with out spacers or level?
 
What engine? I have a 2022 with the duramax and 285 hit the uca and wouldn't fit. Ever other post said it would fit
 
285/60R20 does fit on a stock 5.3 LT trail boss no spacers no level.

I have a 22 TB and put 35-12.50-20 with no rubbing after trimming the mud flaps.

I’m running a 6 bds lift with 35x12.5 x18 -12 offset fuel wheels… my right front tire has very minor rubbing on the inside of the fender in reverse, all mud flaps are removed from my truck.. No spacers needed to clear calipers with these wheels..

Looks really good! Do you have a level kit or any kind of lift on your truck
Thanks! No leveling kit or lift kit all factory. I have noticed hard left turn backing up I get a very little rub on the passenger side!
 
will a 285 70 R18 fit a 2020 lt trail boss
Sorry answer: Yes.

Long answer: I'm running 285/75r18 on my 2020 Trail Boss LT with no lift or level. I was rubbing on the mud flaps when turning, but later deleted them. Only rubbing that remained was very slight while at full lock in the rear of the front wheel well liners. At 5,000 miles I rotated the tires and the rubbing went away. 285/70/r18 is about a half inch diameter smaller than what I'm running, so I believe you'll be okay. You might have a barely noticeable rub from the mud flaps, but that can be resolved for cheap or eventually go away as the tires are worn.
