Just mounted a set of Cooper Discoverer AT3 4S 275/60R20 on my Big Horn Crew Cab 4x4.
Pictures do not do it justice. I was going to go with a 34” tire but I did not want an LT tire and this looks better than I thought it would. IMO you lose nothing compared to the OEM Bridgestones. Better looks, better handling, better performance all around,etc.
Also recalibrated the speedometer with Alfaobd.

Still need to level it. Also installed my Bilstein 5160s in the back, but still waiting for my 6112s to show up.
