Does a 285/55r20 rub on a 2017/2018 Silverado/Sierra with Bilsteins?

[Ed Peck]

Not to beat a dead horse but I can only seem to find info on 2014-2016....

My Truck:

2017 Sierra CC SLT 5.3 with the stock 20in (20x9) rims & Bilstein 5100s at 1.25"

 

I want to get new tires (nitto ridge grapplers or toyos etc) and I would like to move up to a 285/55r20 if possible. From what I've read I know the UCAs changed for 2017 making guys experience rubbing on the UCAs with 33s on levels.

 

Was wondering if anyone had done a 285/55 on stock rims with stock height or Bilsteins and did they rub, or rub all the time/just full lock? TIA

I have 285/70/17 BFG ko2 32.7” tire on stock wheels. They didn’t rub stock but were close to hitting wheel well liner edge at full lock. My 5100s 1 notch below top or 3 up from bottom gave truck 1.75” lift and now looks like I could fit a 33.5” maybe 34 but a34 would touch full suspension travel

 

I have 2018 max tow with steel upper and lower control arms.
