Ive got a 2015 GMC sierra All terrain and am running 275/65R20 Nitto Trails with a 2.5"RC level. I rub the fender liner when turning probably 80% of the time. Also rub the sway bar at full lock every time.
I also put 295/60R20 Nitto Trails before this set. The 295 rubs like hell. Rubs on sway bar significantly, rubs on liner, rubs on metal behind liner. For those who say they do not rub, Y'all must be crazy. Truck also looked too small for the tires that big with only a level.
My buddy has a 3.5" RC lift and he is running the 295/60R20 Nitto trails. HE even rubs too, including sway bar and fender liner.
